crankshaft -NARAKU- racing full circle for Piaggio 50cc

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

The Naraku full cheek racing crankshaft increases the pre-compression in the crankcase, which leads to a much better filling ratio. Power RPM shifts to the upper range. The larger flywheel mass of the all-metal design not only increases power, but also torque. In contrast to the Naraku HPC shaft with plastic inserts, however, the full metal version should only be used from 70cc displacement.

The crankshaft is supplied including piston pin bearings._{AI-translation}
