Crankshaft Naraku racing HPC for Derbi Senda GPR , Aprilia RS RX SX , Gilera RCR , SMT (D50B0)

Description

Naraku 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.
