Can anybody help me out with the length of the 35mm forks fitted to later models? From centre of axle to top of stanchion?
Many thanks.
Daniel.

Raymond, was that with the fork fully extended (i.e. front wheel off the floor)Just popped out to the garage and I find 30" or 762mm from centre of axle to top of stanchion.
Frame is 1978 and I'm assuming the forks are too.
Ah, No, not fully extended - bike on centre stand so some weight on the front wheel. Very good point, @arcticXS.Raymond, was that with the fork fully extended (i.e. front wheel off the floor)
Somehow, I think 762 mm sounds a bit short. But I have been wrong before ;-)
When I lifted the wheel off the floor, I made sure to push down on the fender to extend the forks - I don't know why there is a discrepancy. What are top out springs?I just had to measure the fork on my 77 standard (to satisfy my own curiosity, mainly) And I found it to be 775 mm from axle center to top of stanchion tube (excluding the cap/plug).
Maybe the 7 mm discrepancy is due to damper rod design changes between 77 and 78? Or maybe Raymond's 78 has top out springs installed?
Top out springs most often are short (20-40mm) springs that sit outside the damper rod. The purpose is to be a soft stop when the fork is fully extended, like when accelerating hard enough to unload the front suspension fully. Without these springs you sometimes feel a knock or thud when giving it the beans from a standstill. AFAIK, later XS models have these installed .When I lifted the wheel off the floor, I made sure to push down on the fender to extend the forks - I don't know why there is a discrepancy.
