Title: Bmw K75s 1987 shock height
Post by: Jbuffalo on March 27, 2014, 08:21:43 PM

I am looking at the shock length on this bike it is 13.5 inches eyelet to eyelet shock adjusted to lowest point<  Is this a low shock? thanks Jim

I have a progressive 416 that measures 13.5" eyelet to eyelet on center. It came with a K75 low seat that seems to ride lower than my other K75 low seat. But there are other variables there, I.e. stock vs custom seat. I seem to remember my last Progressive 420 at 13.75 and the new YSS I just got also at 13.75. Not an expert but wouldn't whether its a low shock depend more on the measurement at the center of the adjustment range, not the lowest setting?

Also, what kind of shock is it? Are you measuring the eyelets on center? Finding the model # might help determine what the specs are.

For what it's worth...

Van:  I will look on the shock to see what it is.  I measured it again off the center stand and it is 13.25 thanks Jim

I have a Progressive 412 short that measures 13 1/4 with bike on the centerstand.  I think the standard length is 14"

I could not find any marking on the shock.  It looks like a stock Bmw K  shock.

A OEM shock to a K100RS measures 348mm c/c unloaded. The spring and the internals is a bit different, but
I'll Guess the unloaded length is the same.
