Description

The Wiseco WPC101 crankshaft kit is engineered for CR250R racers who demand reliability under extreme combustion loads and sustained high RPM operation. This factory-assembled unit arrives precision-trued to OEM specifications, eliminating the guesswork of bottom-end rebuilds and getting you back to racing faster. When you’re pushing 12,000+ RPM on the track, a properly spec’d crankshaft isn’t a luxury—it’s essential insurance against catastrophic engine failure.

This complete kit removes the hassle of sourcing individual components by bundling everything you need: the crankshaft assembly, top-end bearing, main bearings, and gasket set. Double-forged connecting rods, shot-peening, and case-hardened rod bores work together to maximize fatigue resistance and dimensional stability across hundreds of race hours.
