Seen a 2000 k1100RS exhaust, can this be made to fit an 85/6 K100?? Thought someone on here had tried but I can't find the post.

A K1100RS exhaust will definitely fit the K100, you will however not be able to use the auto retracting feature of the sidestand.  Also if you do make sure you use the following bracket and absorber to help prevent the possibility of the exhaust cracking.

13	18 21 1 464 437	SUPPORT	0.14	1	$16.67
14	18 12 1 464 754	ABSORBER	0.10	1	$22.68

One word of caution however is the K1200RS exhaust will NOT fit.  As I had trial fitted one and the protrusion that goes under the transmission ran into the front of the rear tire.  And my 1985 K100 has a paralever rear end so it even has a longer wheelbase then standard 1985 K100.

The reason I mention K1200 exhaust is your post mentioned 2000 K1100 which does not exist.  So it may be a 2000 K1200RS exhaust, or the person got the year wrong.

Cheers.  Dave.

Note that all pre '86 K100 models have a different mounting point (round) for the exhaust from later models which would have to be modified. The difference is in whether the bike has rubber mounted footpeg plates or the later straight bolt-on type. Also, if the exhaust is from a 16V model then there are potential centre stand clearance issues but which are not insurmountable. If it's from a 2000 K1200RS (not K1100RS) then the upswept angle is all wrong for earlier bikes if original pannier use is desired.

Very true on the mounting point difference, The K1100rs exhaust I have came with the plate (#20 in the exploded diagram) and the other mounting hardware which bolted up to the transmission.

Thanks for the info fella's.

Seller states it's from a 2000 K1100RS and the silencer is upswept although I'm unlikely to use this bike with panniers and I won't have the side stand retractor fitted as its potentially for a café racer project.

What drew me to the system was the  kinked pipe No 4 pipe. I've seen that design on aftermarket performance exhausts to maintain equal primary lengths.

What concerned me was whether or not the protuberance would clear the rear wheel and centre stand.

That is definitely a K1200rs exhaust and will not fit a K100 due to the rear wheel clearance issue.

Thanks Dave, that's saved me a trip out to view.

No problem,  I loaded my bike on the trailer when I went to check out the same K1200rs exhaust for my project.  I am just glad I did or I would have spent $200 and not been able to use it.

Cheers.

Dave.
