Wiseco Honda CRF150R 2007-2024 Crankshaft Assembly WPC149

A worn or damaged crankshaft compromises engine reliability and performance—especially in a high-revving four-stroke like the CRF150R. The Wiseco WPC149 assembly gives you a complete, factory-assembled solution that restores your bike to OEM specifications or better, with components engineered to handle sustained high-RPM operation. Whether you're rebuilding after wear or upgrading for durability, this kit eliminates guesswork and ensures your bottom end can handle whatever you demand from it.

The WPC149 includes everything needed for a complete bottom-end refresh: a precision-trued crankshaft, top-end bearing, premium main bearings, and a full gasket set. Each component is manufactured to tight tolerances and assembled by Wiseco, saving you hours of labor and the risk of assembly errors. The double-forged connecting rods deliver exceptional dimensional consistency, while shot-peened surfaces reduce internal stress concentrations that lead to premature failure. Caged needle roller bearings are optimized for high-RPM applications, and precision honing of bearing surfaces maximizes oil film strength—critical for longevity in demanding conditions.
