TOPIC:

I have a pair of random spare Z1B right side fork legs with nice clean bores. These were completely dismantled and then steam for inspection. The seal recesses are nice as are all of the threads with the exception of the one fender boss eyelet that you can see has been repaired - but still holds a bolt no problem. 
While these are Z1B specific body style with the #2 in the backside of casting - they will work on any Z1.

Two R hand lowers won't do anyone any good. They'll need a L and R side for them to work.

I’m interested. I have a RH with a broken boss for the caliper bracket.
