CRANKSHAFT BOTTOM KIT 05-07 CR125, WISECO WPC177 HONDA MX
Wiseco Crankshaft assembly with Main Bearings and Gasket set WPC177. Precision-trued to OEM specifications. Factory-assembled connecting rods are double-forged for superior dimensional consistency. Shot-peening eliminates residual stresses and blends rod forging surfaces. Corrosion-resistant surface treatment. Top and bottom end rod bores are case hardened to 58-62 RC for optimal bearing running surface. Crank pin bearing radial running clearance is optimized for maximum performance. Precision honing ensures an ultra-round bearing surface. Engineered oiling slots maximize rod strength and bearing life. Double-drilled small ends provide piston pin with extra lubrication and cooling, reducing top end distortion due to thermal transfer from the piston. Silver-coated bronze phosphor thrust washers with dimpled design increase oil retention and reduce friction between rod and washer interface. Crank pin bearings are manufactured with the highest quality. Part No. 56-233.WI.C.

FULL DESCRIPTION
Wiseco Crankshaft Bottom Kit
This Wiseco Crankshaft assembly includes Main Bearings and a Gasket set, designed for enhanced performance and durability. The connecting rods are double-forged for superior dimensional consistency and improved grain flow. A shot-peening process eliminates residual stresses and smooths the rod forging surfaces. For corrosion resistance, a special surface treatment is applied.
The top and bottom end rod bores are case hardened to 58-62 RC to optimize the bearing running surface. Crank pin bearing radial running clearance is precisely calibrated to ensure maximum performance. Precision honing guarantees an ultra-round bearing surface. Engineered oiling slots maximize rod strength and extend bearing life. Double-drilled small ends provide the piston pin with extra lubrication and cooling, reducing distortion of the top end due to thermal transfer from the piston.
