The WISECO Crankshaft Kit for Honda CR250R models is a factory-assembled crankshaft assembly precision trued to OEM specifications. It features a double-forged Wiseco connecting rod designed for dimensional consistency through improved grain flow, along with shot-peening that helps eliminate residual stresses and smoothly blend the rod forging surfaces.
The crankshaft kit includes a corrosion-resistant surface treatment, optimized crank pin bearing radial running clearance, and a precision-honed, ultra-round bearing surface. Precision-engineered oiling slots are designed to maximize rod strength and bearing life, while double-drilled small ends provide the piston pin with additional lubrication and cooling to help reduce top-end distortion caused by thermal transfer from the piston.
This kit includes the crankshaft assembly, main bearings, and bottom-end gasket kit. It fits 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, and 2001 Honda CR250R models. Distributor part number: 09210090. Manufacturer part number: WPC101.
