Hi, I have a opportunity to buy k 1200 rs/1999. 99000 km. Not expensive, looks nice, with paniers? Anybody experienced with that bike for advice? What to look?

Thanks in advance

a) Look for ABS pump failure due to lack of required brake fluid flush. The pump is very expensive, though there are companies rebuilding them.  b) Loose final drive to swingarm bearings. c) Sloppy timing chain, worn guides. BMW has a 60K timing chain 'tune up kit' for the K12 motors which consists of new plastic guides. Caution, the oil/spring tensioner falls out of the motor when you remove the front engine cover, unlike the K75, K100 & K1100. d) Output shaft/bearings making a howl when you decelerate. 130bhp is asking a lot of that component, as well as the alternator/starter drive clutch. The inner cage can 'frag' causing small bits to circulate in the engine oil. e) Cracked exhaust headers. f) Failing main bearing in the final drive....

...and the general thorough going-over of any mechanical thing before purchase.

Otherwise, though heavy, complex in suspension and wiring, compared to earlier Bricks, and a bit long in wheelbase, they are the bomb!

Would like add some more info....as with other paralever bricks, check the
paralever bearings in front of the FD.

And early models have a history of a leaking clutch slave cylinder, forcing brake
fluid into places it's not supposed to be.

Inge, it's in the details. Wink  Good pojnt on the clutch hydraulics. The early versions' clutch slave cylinder did have a leaking issue.

Nino, no, 100K is not too much with any K as long as the maintenance has been done. These engines and their chassis are tough and known to go several thousand with proper care. But of course there is much more that could go wrong (see the list) on a higher mileage bike if it was not loved and cared for. Best to either have an impartial scrutineer go over it or have a good squiz at is yourself, confidence in your abilities and an eye for detail being the keys.

That seems a fair analysis, though you make it sound (ABS pump failure, swingarm bearings, timing chain, worn guides, oil/spring tensioner, etc.) as if reliability is in question.

That's a lot to consider! And, how does one check all of that before buying? I think we need a buyer's guide like the one we have for the K100 (anyone?). ❤

I plan to go over my '98 1200RS with 34K miles quite thoroughly over the winter. Hopefully, the mileage is accurate and I can get it back on the proper maintenance schedule to prevent such failures.

TWB, also while we're on the subject.

Last year sometime I remember you posting you had purchased a 1200RS and just put  LEDs in the instruments when you returned it for some unknown reason. Could you tell us why you returned that bike?

That musta been someone else. I have a GT version but never considered an RS and the last LEDs I've touched are in my K100RS back in OZ.

Pardon if I 'make it sound like' but if you look to buy anything and you've seen something that you know is expensive and/or has a failure rate, due to (quite often) simple neglect by the owner, more than once in a particular brand/model you'd be wise to proceed with caution and to pass the knowledge to those who ask...

This is not a case of avoiding the K1200 at all. Its a quick assessment of the things that go in time and believe me its a short enough list because if you do those then you have a great bike and a very saleable one. Or if they are done you have a great buy.

When I bought the LT I looked at the Pan European. Then found they have issues with exhaust corrosion and significant swing arm corrosion as well as a potential final drive issue. The first two are very expensive on them, the exhaust is mild steel so they rot. Thing was the Pan was €3,000 upwards, the K came for €1,000 and despite the list of things I didn't even spend €500 on it and that included fixing defects declared to me by the vendor. I reckon I came out of it well.

Most who buy the K love them and I meet very few unhappy owners or former owners.
