Description

The Athena Racing Crankshaft is a high-performance 10mm wrist pin crankshaft designed for the Zuma 1 vertical engine. It features a lighter crankshaft and special bearing cages, differing from the original kit with its solid crank shaft handles. These handles are entirely milled to reduce the volume of the crank handle case, optimizing performance for racing applications.
