Possible 85 K100 purchase

As I said, I was riding a new R1100RS when I bought my first K, an 85 RS. I found the vibrations of a higher frequency than you get from oilheads, but the twins seem to have a greater amplitude. The vibes didn't seem that bad to me, but then I bought a K1100, which has much more rubber mounting (pegs and grips). A definite improvement. Then I went and bought a K1200 (rubber mounted engine). Smooooooooth!

That's the case with the CB line, also. The 750 is hard-mounted to the frame and uses a chain for the final drive. The 900, 1000, and I believe the 1100F all went to rubber mount points and shaft drive, offering a much less buzzy ride. I toyed with the idea of adapting rubber mounts from a 900 to fit the 750, but it would be much smarter just to get a 900, come to that.

I'm hoping to get to look at the K later this week and see what it's like in person. I watched Chris Harris's video on prebuy inspections for K75s and K100s, and also the video on swapping out the final drive. Good stuff.

Richard,

If you want smooth get a K75. Nothing is rubber mounted. No need to. Smoothest running engine BMW ever built.

Not quite the power (20-25 less) but plenty quick one up. The K75S is a lot of fun.
