MZ/MuZ Riders

Hi all,

Some oil on rear wp shock reservoir, leaking or it may came from chain, What do you think? And rear wp shocks are fully re-buildable?

Thanks.

clean it off first..then see if you can see any leaks after riding....
I think they are rebuildable..

The bike is in a distant place and i may buy, not owner at the moment.

Thanks.
