Hi there it's Tom from Gold Coast, Australia!

I did a trip over to Uluwatu, Bali several months ago and loved the cafe racer/scramblers that they had over there mainly done by DEUS Customs. Once I got back home looked around at different makes/models to do my own project however wanted a bike with enough grunt as had a Honda CBR1000RR 2012 beforehand. While looking around at a heaps of makes/models found a lot of them were either 250cc or 400cc which wasn't what I was after until I randomly l stumbled across a K100 RS 1985. Since then been in love with it especially the whole engine tilted over on the side look. This is my very first custom cafe racer build as also brought stock standard dirt bikes or road bikes and added a couple of extra aftermarket parts. 

I have currently brought a K100 RS 1985 bike about 3 months ago. It was registered and came with a roadworthy certificate. The bike itself ran really well mechanically but cosmetically it was a bit rough so was perfect for a cafe racer project. I completely stripped the bike down, sanded and cleaned everything back, re painted the engine a gloss black and then frame, forks, callipers satin black. Had the wheels powder coated gloss black too by Coastal Powder Coating on the Gold Coast. The tank, seat and mudguard I painted the original navy blue colour (have included picture of what it is currently at in my profile pic). I ran into trouble while painting the bike as working out of a storage shed atm as living in a apartment building. So initially used 2 Pak in a pressured can however was reacting to everything even after was sanded, cleaned down. Ended up getting the compressor out and the spray gun it doing it properly and it came up really well (I would of done this in the first place if I was in my own garage haha).

I brought a couple of aftermarket parts from the cafe4racer.eu site such as the seat/cowl, ace well speedometer, rearrest, headlight and slip on exhaust. I have found the parts all fit quiet well just need a bit of modification and tweaking to make it look perfect. Other parts I have brought mainly from BMW Nerang were just general maintenance to the bike such as replacing spilt/worn rubbers, replace all fluids plus filters, worn brake pads, new tyres (heidenau scout k60), handle bar and grips. I think just getting tyres to fit the rims I had a lot of troubles. I had to research heaps and ask around a couple of tyre places as found a lot of the information on the net was outdated or it was not the look I was after. 

To install the speedometer I made up a bracket that will will hold the speedo, ignition switch, hazard light switch and also the bracket for the head light all in one plus still give it a classic look. I will post pictures in the thread afterwards from beginning to current.

Currently I am at the stage of wiring up all the electrics this afternoon (thanks to Andrew who I brought the bike off has helped out heaps with giving me pointers and diagrams to assist with wiring up the bike), then will put all new fluids into the bike and lastly have the auto trimmer make up a nice seat for the bike then she will be ridable haha. If there is anything more specifically you would like know know about the build shoot us a message. Stay tuned for the for the new pics once its done completely  Very Happy 

Cheers Tom

Good work so far. BTW there are forum members looking for some of the bits you’ve removed, I know specifically mirrors for sure. If you offer up your unneeded parts I expect you’ll get some action.

Hi
I like your choice of handlebars, I think they suit the bike much better than the clip-ons that seem to get fitted all the time. Also, you haven't gone all no-ass with the seat unit -it looks properly proportioned and suits the bike, unlike a lot of the way too small 'fat-guy-in-speedos' units that don't suit the big-chested tank.

And...Raask rearsets, wahay! Can you believe those exact same things were around in 1988!

Nice, why did you choose that look?

Thanks guy really appreciate the feedback! Just did majority of the wiring up on the new speedo and everything in between now its just off getting the seat upholstered atm! Had to do some tinkering around obviously as having LED lights, fixing up the fuel gauge so works properly with the speedo haha. Should be on the road in one week can't wait!

Club_C Sweet thanks I have chucked an ad up on gumtree and on this forum and sold a bit of it so far which works well.

Thanks heaps Chris yeah I ride a lot of dirt bikes and down hill mountain bike riding so prefer those handlebars I find them more comfortable and have better control. Yeah I literally looked through heaps and heaps of pictures of different K100 cafe racer builds and thats what I was finding on a lot of the bikes looked really good however little turn offs for me was the seat either being way too big or way too small so was wanting the bike to still look proportioned and clean (not looking like it was hacked up with a grinder). Hahaha yeah that style rear sets are older than me by a year Shocked. Umm I really don't know why I choose that look I think just after researching different builds and picking what I liked the most from each bike/build and putting together what I preferred really. Everyone has their own taste and I know a lot of people on here don't like seeing a K100 chopped up haha.

Do you have a direct link to the seat?  I am thinking of making my own, but...your seat looks amazing!

Hiya jmccrary

I thin Tom used a seat from cafe4racer - if you google them you'll see one of his pics on their website. 

I've just ordered one myself for the K75k, so I'll post up some pics of it soon enough.

Cheers
chris

Chris,
I found it on the site just after I sent the message.  If you can, will you post pics of the install including any adjustments to the frame that needs to be made?  I am between ordering this type of seat vs making my own using the factory seat pan.  TIA!!

Justin
