High-quality crankshaft from Naraku. Produced according to OEM guidelines of Japanese vehicle manufacturers. Made in Taiwan!
This HPC Racing full cheek crankshaft increases the pre-compression in the crankcase, which leads to a significantly better filling ratio. The power speed is shifted to the upper range. The plastic inserts used due to the full cheek design increase the overall weight only slightly compared to standard shafts. As a result, this crankshaft can also be used on 50cc cylinders without any problems.
The NARAKU Racing crankshaft is supplied including piston pin bearings.
