Currently looking for a new crank (has to be a 60/110).

Has anyone ever used the JB Super Corsa in a TS1?

Is the big end bearing high quality?

The MB ones are too pricey, BGM / ScooterCenter arent available at this time and i don't trust the MecEur / Mazzu ones.

Thoughts welcome! :-D

JB puts these cranks into engines that he builds for his customers and he doesn't want any come-backs, so he must trust them.

When you see JB fitting someone else's cranks into the engines he builds, then it is time to think again. The fact is, he started building his own cranks because he kept being let down by cranks manufactured by others (twisting, weights falling out etc etc).

The quality of the webs seems very high. They are full circle.
