I have had my ohlins on my XTR for 16,000km now and it has handled everything great and is very comfy.
It has done dirt and our very crappy roads here in Aus with ease.
It is without doubt one of the best improvements to the bike.
By the way rear shocks for the X/R are different to ones that can be fitted to the Z.

i made a mistake. i want to write damping not preload.

finally i bought wilbers

Would shock off a R1 fit.?:064:

Search on google and you will see that bottom of the shock in not the same so that,s first problem, the other it,s to short travel.
