EBC Clutch Kit
mark in NY
Nice kit for the money
So far so good. nice complete kit. Positive engagement of the clutch every time. So far i have over 100 miles on it mostly dirt. It was for a klx 300r and i installed it in my Kawasaki super sherpa kl250g with a 300 kit in it because the original clutch started slipping with more power and being 20 years old.
