Hi Everyone! I'm in the market to pick up a nice K bike and there are currently a couple examples in my area that look interesting. One is a 1988 K100RS White/Blue which has 42,000 miles on the clock and is selling for $2,500 USD. The bike appears to have been serviced and maintained and when standing from about 15 feet away, the bike looks flawless. Upon closer inspection it becomes clear that the bike has been dropped at least once and has some touched up battle scars. Sun damage on the controls is evident also, but everything seems to function. It is not a garage queen but it does appear to be a reliable and solid platform. ABS works good. Splines are lubed and appear to have been routinely serviced. Compared to most bikes that are nearing 30 years of age, this bike stands out as a survivor. Replacing a few bits and pieces (which are becoming harder to find) and a new paint job would really bring this bike back to its glory. However, relative to the amount of time and money invested, it would still be a 30 year old bike and I'd never get my money out of it. So my plan would be to just ride the bike as is and not worry about the cosmetics too much, since the bike looks good overall.

This is the bike I had been giving serious thought to purchasing, that is until I found a 1996 K1000RS for sale with 70,000 miles on it which is selling for $2,900 USD. This bike appears to be in very good condition and doesn't appear to have ever been in an accident or dropped. At this point the '96 K1000RS looks like it might be a better bike for the money, but I'm not sure. Comparing the price of the two bikes, it does seem that the 1988 K100RS is a bit overpriced at $2,500 USD.

Any thoughts on this or opinion on what the 1988 K100RS might be worth?

Take the K1100RS They re a big improvment on a K100RS. The K100 is a Special Edition of the last of the 8v RS and will become more valuable over time but the K1100 will have the better brakes and the second generation ABS which along with more power makes it a far better bike to ride.

Thanks for the feedback. I surmised that might be the case. I looked up the paint color schemes and I recognized that the white/blue was a special edition, but according to the web search I found, that color combo was for the model year 1989. This bike is a 1988 model. Perhaps it was offered both years? To be honest, I really do like the K100, I just wish it were in better cosmetic condition. I've been online researching and doing searches for parts and it appears there's a limited amount of parts still available for this bike. So I'm somewhat hesitant. The $2,500 price seemed like a very reasonable deal, until I saw the 1996 K1000RS for only $400 more. For the difference in price, the K1000RS seems to make more sense. As you pointed out I would enjoy the upgrades and get a bike that is almost 10 years newer.

That blue and white K100RS sounds not bad, they are nice model. The 1996 bike will surely be a K1100RS and not a K1000RS, they are a very nice K!!!

Do bear in mind that a lot of Ks are let fall over as opposed to being dropped, especially to the right hand side. It can be hard on the fairing and mirror but doesn't reflect a bike actually being dropped.

What you really need to do is buy both. Sooner or later you will have a second K anyway.

Olaf is right. With a bit of help from Tom G, I've gone from 4.75 to 5 K bikes!

One is never enough.

Though the difference isn't that great in reality, the K1100RS will feel much heavier when you ride it, probably due to some additional weight but also the fatter radial tires.

This is not to knock the K1100RS. The front brakes are massively better and the forks are better too. The body work is better looking too.

(Get a Mystic Red one. They're the fastest.)

I agree with all of the above. While you will enjoy riding the 88 K100RS, the K1100RS with better brakes, wider tyres with radials (no radials for the 88 K100), better forks and paralever drive, is a much nicer machine to ride... but what sold me was slightly more horse power and much more low-down torque.
If the 1100 checks out mechanically I'd go for that.
There's info here on the forum about what to look for when checking out a new bike.
cheers

You can put radials on a K100. I have them on mine. (But you do need a 3-spoke 3" rear wheel in order to mount a radial.)

Welcome TAK100

As the proud owner of a Special Edition, I've done a bit of research into the production year issue and have concluded: it's a mystery.

I've spoken to people and have seen documents that strongly support a two year run and a one year run. I personally think they all came out as 89's as it was for the last year of the 2 valve engine and they wanted to do something "special" for the last year. According to my serial number, my bike was built late in 88 but that makes sense to be sold as an 89. I haven't seen anything definitive concluding a one or a two year run or the exact number of SE's made.

I've seen a couple of K100RS' painted up to look like specials BUT you stated that the one you were looking at has ABS making it a real SE, the first bike with it. I know there is a BMW sales document out there somewhere saying that ABS was available for all 89 BMWs but I haven't seen any other information showing this.

As most have said here, get both bikes! If not, get the one you will be most happy riding.

You haven't mentioned much about you and your personal riding experience. I'd offer this observation. If you have not had any (or much) experience riding heavy bikes, do keep in mind the later models grew ever more porky. There's a reason many show signs of being dropped (as opposed to being thrown down the road). They can be a hand full at low speeds and on surfaces that are not perfect (as in the case of gravel). Once a K-bike gets tipped beyond a certain point there's no stopping it. It's going to fall. The saving grace in such instances is they are pretty tough. Just be sure you don't have a leg or arm in harm's way. Shocked
That said, I would add the K-bikes are pure joy out on the open roads and through big sweepers!

When talking about model year just remember that the US market seems to be different in defining model years to the European market. Don't ask me why. What a Face

I have used both the K100LT and the K100RT. When I went from the 92 LT to the 84 RT I was amazed at the difference. The 84 RT feels much lighter and much more nimble despite being essentially the same bike and fairing but less gadgets and no ABS. It also felt much lower, attributed to the fact that the LT has a Comfort seat on it. Since I got the RT I have lowered it a little to the point where I can get both feet flat on the ground and it feels less like being on a bike and more like in it. The RT I can now throw around roundabouts and curves and quite enjoy it.

I tried a K1100RS for 88 last Christmas and while it was amazing in terms of everything it felt so much more heavy and higher centre of gravity that I personally could not go for one. If I were 2 inches taller I would definitely go for it. A little investigation revealed it is about 40 kilos heavier than my 84RT.

I know a guy who says his US SE with ABS is titled as an 88. I'm going to help him with some stuff in the near future so I'll try to remember to check out his VIN to see what the build date is.

Hi TAK100

Like nvboy my RS SE was built in October 1988 although it was not registered until late in 1989.

It is great to have a choice. For me the performance of the K100 is more than sufficient. I really do not want any more weight on a bike than is absolutely necessary. Filtering through London traffic this morning proved that point. So for what my opinion is worth go for the K100RS SE, have the satisfaction of riding a true eye catching classic with a bit of patina to prove it has been places. And spend the saving on a set of progressive fork springs, new tyres or a new rear shock if you think you need better handling.

Regards
Nigel

Spot on Bob, it is a K4 model with horizontal rather than upswept pipes,it is also one in mint condition.OurG models came in a blue or green on days when my memory works. I did fancy that 250 but went straight for the 500-4 instead.

Out of camera that day was one to lust after......a very early CB750-4.

The model year starts in September of the previous year for all BMWs back at least to the beginning of the /7s.
That makes any K produced after 1st September of 1987 a 1988 model but the compliance plates in many countries will call it a 1987 bike because that is when it was produced. Australia however puts them down as when they came into the country so a very late production 1988 model which may have been August 1988 is often classified as a 1989 bike.
I once owned a 1992 Toyota Surf wagon which was originally built for the home market and imported into Australia in 2002 and was classified as a 2002 model by our really smart gubbermint. After much lobbying by the car industry it would now be classified correctly to reflect its real age.

If you register a bike or any vehicle on 2nd January its recorded as being that year, quite clearly it was made the previous year but that system works fine. Most countries work that way so you have to be careful not to mix up model year and year of registration as they can differ. My LT is a production date in late 1991 but its recorded as a 1992 bike on the basis of being the date it came into service. If you buy an unused unregistered K like the one in James Sherlock and register it theregistration will be a current year plate.

It was the first year for K100s in the US so things might have been different for the early litters but I just took apart a bike that was produced in July 84 but titled as 1985.

More accurately, it was when the vehicle was complied, not when it came in.

I know that there were many Triumph Dolomite Sprints that were fitted with a compliance plate in 7/76 because they wouldn't comply with the new emission standards being introduced. Many of those cars had already sat in the storage yard for a year or more. Compliance plates (and some local compliance items, eg seat belts or sun visors)weren't fitted till the vehicle was being readied for delivery to the dealer, it applied to all the imported products.

Thanks everyone for your input, I appreciate it very much. As someone pointed out, the 1996 bike is in actuality is a K1100RS, not a K1000RS. I guess that goes to show how little I know about these bikes. You'll have to forgive my ignorance, it's been a long time since I rode a K bike and that was a K75s. In fact, it's been many years since I've even been around these bikes. For the past 15 years or so my primary ride has been a Harley-Davidson Ultra Classic. For those unfamiliar, the Ultra Classic is Harley's flagship full dresser touring bike. That bike weighs in at 900 pounds. By the time you add fuel and gear the bike tips the scales at around 1,000 lbs. Comparatively speaking, the K100RS which weighs 573 lbs and the K1100RS weighing 590 lbs, are about half the weight of my Ultra Classic. I've been riding 30+ years and at this stage of my life (age 47), the type of riding I enjoy most is touring. I enjoy long distance riding. It's not unusual for me to put 500+ miles a day on my bike when I go on my rides. I'm not an Iron Butt rider mind you, but I've ridden as much as 720 miles in a stretch before, stopping only for gas and a bite to eat. So needless to say, comfort has been an important factor to me, that along with the hard lockable saddlebags, etc. Out on the open road in all kinds of weather, I've found the added weight to be an advantage.

So it's all worked out pretty well for me. Besides the Harley, I've owned a few other bikes besides, so it gave me a nice variety to choose from if I decided I just wanted to go for a short ride. However the reason I'm considering buying a K bike is because my stable is totally empty. I sold all my toys. I've since relocated from Orange County, CA to the Central Coast, near Pismo Beach. I've always wanted a K100RS, ever since I was in High School. As an avid rider, it was the bike I lusted for the most, but that dream was never fulfilled. Over the decades of riding, I had a lot of bikes in my stable at different times and as my focus turned towards other bikes, the K100RS just got further out of sight.As they old adage goes, "Out of sight, out of mind."

Now, having sold our home and relocated to our new place here on the Central Coast, I find myself going crazy not having something to ride. So for that reason, my thoughts have turned to buying the bike of my youthful fantasies, a K100RS or K1100RS. The age of either bike doesn't scare me and as noted earlier I'm not expecting perfection. Whichever I choose, I would address cosmetic issues gradually and focus on just the mechanics for now. What I need is a good solid, well maintained machine. As far as preference goes, I must admit I prefer the color scheme of the K100RS (blue/white) over the black K1100RS. Also, as somebody noted that particular bike may become more desirable in time as it was a special edition and the last of the K100RS model.

So with all of that said, what do you folks think of the price? Is $2500 USD a fair price for the '88 K100RS?

$2500 USD is exactly what I paid for my SE four years ago in Dallas. Cosmetically it was pretty good and I put about $1000 of parts and labour to get it running smoothly and to replace a few parts that were missing. It's my main (and now only) ride and it purrs like a kitten every time. Cosmetics can be taken at a more leisurely pace to get it gleaming again. Depending on how bad the paint is, I would suggest to you that it's only original once and if you paint it you've popped that cherry.

This evening I'm heading out on a three day ride to include Winthrop WA, Grand Coulee Dam, Kootenay Lake in BC then back to Vancouver Island. I don't anticipate any problems either mechanically of with comfort. It's going to rain. Might snow. santa

Having put a few miles on a Harley Road King I can say that it's an apples and oranges comparison. The Harley is more of a plodding, relaxed, comfortable motorhome kind of ride where as the K will be more..... spirited.

There are three models of bike all similar, the K100RS (to about 1988/89) K100RS RS1 which was a 16 valve engine with many other improvements (1989 to 91) and then the K1100RS. The 1100 and the RS1 both had 100 bhp and the earlier 8 valve had 90.
I am very surprised about you honesty in admitting you owned a Hardly, we only use them as farm vehicles here.

Welcome! I'd like to chime in with my opinon as I have owned a 92 k100 rs as well as my current 89 k100 rs. The 92 was faster, handled better and seemed to do everything a little better. The se looks better,lighter,doesnt seem as top hravy. I like the narrower handle bars, more room under the seat and shorter wheel base. Its got Ohlin suspension, oh and did I mention looks better. Got that eye candy appeal. My opinion the se edges out the 92.

An '89 and a '92 K100RS should both be 16 valve machines so should be exactly the same bike. I believe that the '92 should really be a K1100RS as that is when they started. Having said that the US seem to use different model years to the factory in Europe.

It may come down to whether you're talking production or release date. My late '88 production/'89 model K100RT (police) is an 8V. I believe 8V K100 production finished in July '89.
16V production went from March '89 to June '92.
K1100 production was April '92 to Dec '96.
Model release date is usually 6 to 12 month later.

Manufacturers have model years which are independent of exactly when they were actually made or sold or registered. The first production Mustang came out in April of 1964 but was called a 1965.

Guys,

Today after work I stopped by the dealer that has the '88 K100RS for sale and they had just taken in a 2002 R1150RT with only 20,000 miles on it. The selling price is $5100 USD. I realize the Boxer motor is a totally different animal than the inline 4 "K" bike, but what are your thoughts and opinions? I'd like to hear your thoughts about the R1150RT....good and bad.

16V production went from March '89 to June '92.
K1100 production was April '92 to Dec '96.
Model release date is usually 6 to 12 month later.
You mention your '89 police rt being an 8 valve, well it would be as the conversation so far has been about the K100RS which went to 16 valve when the RT didn't. If we are talking about bikes and years then it is only worth talking about manufacturer model years as registration years around the world mean nothing to others.

I have both a K1100LT and an R1150RT (2001 single spark).

The K engine/gearbox is fantastic (I came from a 1978 R100RS). The R1150Rt takes some getting used to after the K. In it's own way though, a fine bike.

If you have the servo ABS linked brakes:

1.Slow speed tight U turnsneed care, because when you drag the rear brake for stability, it also applies the front brake. Easy to get caught out!

2. Check the history of thebrake fluid change regime. The control and wheel circuits are totally separate, plenty of information out there to show how it's done. Numerous reports of servo failure, which is exceedingly expensive. I have just removed my servo and reverted to standard hydraulic brakes, as it started to fail due to high pressure in the rear circuit, followed byno ABS function. This is the second module I have had fail, even given the fluid changes!

3. Some haveproblems with stripping of the gearbox input shaft splines along with t he clutch centre splines. Again bitter experience, as mine has just gone again (second time).

Other Views:

1. Headlight is not as good as it could be, needs upgrading.
2. Handling of the R is better than the K1100.
3. A lot lighter than the K.
4. Hydraulic clutch.Slave cylinder can leak, and is a swinging arm removalto get to replace it.
5. My wife prefers the pillion seat on the K1100, even when I put a Corbin on the R1150.
6. The R1150 can suffer from surging at slow speeds. This can be alleviated with careful setting of the rocker end float and valve clearances.

Just a few quick observations to get the ball rolling.

The 92 was faster, handled better and seemed to do everything a little better. The se looks better,lighter,doesnt seem as top hravy. I like the narrower handle bars, more room under the seat and shorter wheel base. Its got Ohlin suspension, oh and did I mention looks better. Got that eye candy appeal. My opinion the se edges out the 92.
BobT wrote:An '89 and a '92 K100RS should both be 16 valve machines so should be exactly the same bike. I believe that the '92 should really be a K1100RS as that is when they started. Having said that the US seem to use different model years to the factory in Europe.

With respect Bob, your point that Mikes '89 RS should be a 16V is not necessarily correct.
The 8V RS and RT both finished production in the later part of '89.
There was some small overlap in production between the 8V ending and the 16V introduction, and also later between the K100 and K1100 models. Both 8V and 16V RS were in production in '89 and Mike's '89 model RS would most probably have been produced in '88.

Well...I went ahead and did it. After many years of riding other brands, I pulled the trigger and bought another Bimmer. The exact bike I chose however will probably likely have me banned from this forum. After much agonizing debate, I decided to purchase the '02 R1150RT. This bike is in such excellent condition and with only 21,000 miles on the odometer, I just couldn't pass it up. While the '88 K100RS was also in good shape for its age, by probably most people's standards, I just felt that the RT was more suited to the type of riding that I prefer. Also, while the year didn't deter me from considering the '88 K100RS, the overall condition would likely cause my compulsive, perfectionist nature to come out and compel me to spending money on restoring the bike to as near new condition as possible, rather than just ride it and enjoy it as is. 90% of BMW riders would probably find the bike to be perfectly acceptable as-is. It really looks great from 15 feet away. It's just upon closer inspection that you begin to see the faults, broken pieces and those are the things that would drive me crazy trying to repair or replace with parts becoming harder to find. Given that I sold my other bikes and my stable is now empty, I really wasn't looking for a project bike, so much as I was a reliable, daily rider. Perhaps now that I have two wheels under me again, I can consider a project bike down the road. We will see what happens. I still have a soft spot in my hear for the K100RS.

Because I ride an RT, does this mean I'm a trader to the K-bike and must be banned? lol!

Over here we have a very nice man called Bjorn whowe enjoy camping with and we meet for the occasional coffee and chat. Bjorn lusted after a K and ran into the same problem as you and ended up buying........a R1150RT. He comes out with us regularly and we enjoy his company.

Comberjohn is also another well known forum member who has been through a few Ks. He was last seen somewhere around the Pyrenees on an R. Again we all enjoy his company on the forum and on whatever trips we make.

When we meet up we are like minded even though not everyone is on a K.

K pox is sort of infectious and just because you didn't buy that RS which incidentally the riding position would not have suited you does not mean you wont buy one at some point if you do find one in the condition you seek. They are out there and your stable is empty without a K in it. Time will take care of it. anyway lots of the guys here have more than one bike and different ones.

In other words stay with us.

firstly dont call beemers bimmers as previously explained bimmers are yuppie tin tops with 4 wheels, and yes you are a traitor not a trader ??!! but at least its a BMW so i guess its acceptable, and having an obsessive / compulsive disorder is something you should talk over with your doctor , and the same goes for the soft spot in your hear / head maybe you should of bought another HD road king or similar ,heres an example of a well ridden K complete with sidecar and engel to keep the tinnies cool ,20 litre long-range fuel tank , and a bunch of aussie admirers to me this has more "street cred" than some spit polished, pampered " has to look immaculate "all the time i bet your the type that carries an aerosol tin of mr sheen or similar and a piece of cheese cloth as a polishing rag and give it a polish up everytime you stop

I am very surprised about you honesty in admitting you owned a Hardly, we only use them as farm vehicles here.
hey bob some people here in ozland tried to use them for a boat anchor / mooring block but gave themselves a hernia trying to flip em out of a boat HD - hardly drivable , highly dangerous cheers mate

Nah....no cheesecloth or Mr. Sheen necessary in between every stop. I'm not that extreme, thank God. That said, l do like my bikes, like my cars to be in order. Meaning if something breaks, it gets replaced. If it gets dirty, it gets washed. I'm not opposed to owning an old bike, but just not an old, dirty worn out looking bike. On this side of the pond we call those rat bikes. Some people like them and they invariably show up at every motorcycle gathering, like it's some kind of new fashion trend and they wear it like it's a badge of honor. Hey look at me....I've never washed or maintained my bike...EVER! I've never much understood that mentality, but that's definitely not my style. "There's a butt for every seat", as the saying goes.

I'm sure you're right. I probably will end up buying a K100RS, eventually. I'm used to having 2-3 bikes in my garage at any given time. As it happens, I sold all my bikes and other toys so we could move to our new home. We sold our old house and moved in to a newer 5 bedroom home in a very desirable neighborhood where the house sits on 2 acres of wooded land overlooking the Pacific Ocean. It's a little slice of heaven. The tradeoff made it all worthwhile, but now that we're settled in, I needed to have something to ride. The nice thing about my RT is that it needs nothing and the previous owner kept it looking immaculate. Now that I have a nice well maintained/cared for bike, I could consider something else, like that RS I was considering. That would be fine as a second (project bike). At least I'd still have something to ride when the RS is down for repair/maintenance.

The RS is still one of the sexiest bikes ever made, in my opinion.

Hey!
Hey? What do do you mean "hey!" Rick? I would have thought that the likes of you and me were stereotypical yuppies with our assortment of BMWs - with and without roofs & doors, 2 or 4 wheels.


Collectively my K's have the same number of wheels and the same size engine (twice as many cylinders though!)as the tintop - they are just able to operate independently from each other!

As far as my limited education goes, coming from the deep south of the UK, - I've always known all BMWs as Beemers regardless of the number of wheels they have. I had never heard the "bimmer" term before joining this 'ere forum. Is it from that strange language that they call American-English?

Anyway TAK100 - I wholeheartedly agree with Olaf and don't really care what someone rides as long as they enjoy to ride and enjoy their bike - even Hardly riders!!! Shocked There I said it and that will me being banned / damned too!

There is a difference between dirty unmaintained bikes (rat bikes, commuter hacks), dirty maintained bikes, clean maintained bikes and clean hardly ridden bikes. Mine fall somewhere between dirty & clean maintained depending on how much mud the local farmers add to the road and, personally, I wouldn't have it any other way. The key bits are that they are maintained, ridden and enjoyed.

My car bikes and house only get washed when it rains and the tanks overflow, the rest of the water is for keeping me and SWMBO clean. So if the bike looks like a mobile pig pen then you know it hasn't rained for fnages

TAK100 wrote:Hi Everyone! I'm in the market to pick up a nice K bike and there are currently a couple examples in my area that look interesting. One is a 1988 K100RS White/Blue which has 42,000 miles on the clock and is selling for $2,500 USD. The bike appears to have been serviced and maintained and when standing from about 15 feet away, the bike looks flawless. Upon closer inspection it becomes clear that the bike has been dropped at least once and has some touched up battle scars. Sun damage on the controls is evident also, but everything seems to function. It is not a garage queen but it does appear to be a reliable and solid platform. ABS works good. Splines are lubed and appear to have been routinely serviced. Compared to most bikes that are nearing 30 years of age, this bike stands out as a survivor. Replacing a few bits and pieces (which are becoming harder to find) and a new paint job would really bring this bike back to its glory. However, relative to the amount of time and money invested, it would still be a 30 year old bike and I'd never get my money out of it. So my plan would be to just ride the bike as is and not worry about the cosmetics too much, since the bike looks good overall.

This is the bike I had been giving serious thought to purchasing, that is until I found a 1996 K1000RS for sale with 70,000 miles on it which is selling for $2,900 USD. This bike appears to be in very good condition and doesn't appear to have ever been in an accident or dropped. At this point the '96 K1000RS looks like it might be a better bike for the money, but I'm not sure. Comparing the price of the two bikes, it does seem that the 1988 K100RS is a bit overpriced at $2,500 USD.

Any thoughts on this or opinion on what the 1988 K100RS might be worth?

Face it, the first K-bikes, the 8 valve ones, were not accepted well by the press. Not as much power and a less than stellar riding experience is what you got so sayeth the press at the time. What you did get get was a motorcycle that would run forever, usually. In the USA the value seems to be in the $2500 ~ 4000 region depending on condition and model. The RS seems to be the most valuable, the RT/LT not so much. BMW improved them continuously over the years, my limited research seems to indicate that the 4 valve K-100 bikes are worth about $500 more all things being equal. The 1100 models are worth about $1000 more, all things being equal. When the K-1200 rolled around a great deal had changed, and since the production run was long the first of them seem to sell in the $3500 to $5000 range - towards the end the bikes are worth today in the $5~7000 range sold private party.

That's what I know about this...A great value in used motorcycles.

I recon that G5 is a K4 as the K4 had the drum brake, well mine did.

Spot on Bob, it is a K4 model with horizontal rather than upswept pipes,it is also one in mint condition.OurG models came in a blue or green on days when my memory works. I did fancy that 250 but went straight for the 500-4 instead.

Out of camera that day was one to lust after......a very early CB750-4.
Good spot on the 250/350, that is indeed a K-4. G was the last year before the 360, it got a new disc brake, a separate indicator pod, a white stripe next to the black stripe and a couple of little tweaks.

Early CB-750, like this one?



This one lives right next to my K-100 in the garage. When you ride it though it feel really archaic. Not to say it doesn't ride well, just not as much refinement as a later bike, like my CB-700SC. A lot improved in those 12 years.



Wait, this has nothing to do with K Bikes. Quick!



Seems odd you could get all this for $2500. Seems like it would be worth more. I've has this for 28 years now.

Here's a quick pic of yours truly with the RT I purchased recently. I'm enjoying the bike very much and I'm glad that I bought it when I did. The bikes was just to nice to pass up for the condition, mileage and price. Although, it is feeling a bit lonely in that big old garage all by itself. A stablemate may be in it's near future. We'll just have to see what Santa brings for Christmas!
