crankshaft Naraku racing full circle for Piaggio / Derbi D50B0

High quality crankshaft from Naraku. Produced according to the OEM guidelines of Japanese vehicle manufacturers. Made in Taiwan!

This heavy-cheeked racing crank increases the pre-compression in the cases for improved filling. The extra inertia improves performance and the performance moves to the upper rev range. As opposed to the HPC crank with plastic inserts, this full metal version should only be used above 70cc.

Delivery includes small end bearing.
