basic specification see folder specs 

you need to have a spacer to clamp the fork!
Otherwise you risk to break the clamp!

if you have leaking issues with your master break cylinder for the front brakes, check first if you still have silver looking housing, the brighter one in the picture.
If so, throw the silver one away and buy a "grey" one. The silver one is the first series, replaced by the end of 1993 by the grey version.

The grey one is worth to invest a repair kit.
