I was reading back through fuel injection synchronization, and vibration, and knew this would be a good place to ask:

Did any of the K-bikes (K100, K1100, K1200, K75) have rubber mounts on the engine?  Or was it always on the handlebars/footpegs?

I know early K100 had rubber footpeg mounts, and later models did not.

The RS, RT & LT models have a rubber bush in the forward engine mounts. 

The naked versions have solid mounts as does the K75S.

The K1100 has rubber mounted footpegs but a completely different system to that fitted to the early K100s.

I love to know just how different a k100 rs,rt,lt would be if all 5 mounts were rubber like the front 2 on the rs rt lt's, I know they design frames to manage vibration but ya just have ta wonder.

That would mean the rear and front wheels would have a rubber mount between then.  Reminicent of the Norton Comandos with the Iso-elastic mounts on the engine and rear wheel.

yes it would, you then are at the mercy of the vulcanising merits of the rubber mounts, but would it detract from the ride experienced by all at present or would it improve the experience by lessening the vibes? or just shift them to another entry point. kawasaki had rubber mounts on the GT550 and gt750 from mid 80'sish from what I remember of looking at them at the time, I remember what a badly set up commando was like so wouldnt want that for any of us

There's nothing like riding a bike that's hinged in the middle to test the control of the old sphincter muscles!!!!!

A mates Kawasaki 350 triple comes to mind...

And my old ram air gt550 also gets the nod

Yep. The old kwak 750 H2 "widow makers". The bikes I cut my motorcycling teeth on. Ahh joyous memories.

and for post number 800, we can say i've never ridden one of those quackas, my mate wombat has a kawasaki 250 triple twostroke that was fun, i must say the triple twostrokes were or had one hell of a note on the throttle, loved to get the suzuki gt550 screaming, that is also how i found out about the frames wonderful handling failures.

Looking at the models with the bushed forward frame mounts, it suggests to me that they are there to deal with vibrations transmitted to the fairing rather than the rider.

The K75S doesn't need them as the fairing is mainly mounted on the headstock in a very different fashion and the two, rear lower mounts (to the frame) have their own rubber bushes.

Good point mikep, the naked K's have solid mounts, wonder if any of the boys who removed their fairing had ever ridden a naked K to notice any difference with the rubber mounts new nakeds they greated, maybe too insignificant to notice without the fairing to amplify things
