crankshaft Naraku racing HPC for Minarelli AM, Generic, KSR-Moto, Keeway, Motobi, Ride, CPI, 1E40MA, 1E40MB

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

This heavy-cheeked HPC 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. The crank design, with plastic inserts, only slightly increases the mass over the original making it ideal for 50cc.

Delivery includes small end bearing.
