Crankshaft NARAKU Racing Full Circle 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 crankshaft increases pre-compression in the crankcases for improved filling. The extra inertia improves performance and shifts power into the upper rev range. Unlike the HPC crankshaft with plastic inserts, this full-metal version should only be used above 70cc.
Small-end bearing included.
