This is the one to get when you blow your crank wristpin by varnishing your crankcase using chainsaw oil. The circlip retaining ring seems a hair lower than on the stock crank, meaning you are going to have to push that spring-loaded disc down HARD to get it in. No big deal in the end. It fit really snug and needed only the tiniest magneto-side shim to perfect the fit in my ZA50.
Looking forward to many miles of happy ripping.

Finally an aftermarket ZA50 crank!

ZA50 cranks are one of the weak links to your upgraded 2 speed build. You know you need to change out those seals anyway too. But now there's an aftermarket crank with needle bearings machined to exact specifications! And it costs less than buying a new conrod and sending your old crank to get rebuilt! What are you waiting for?
