CRANKSHAFT BOTTOM KIT 06-09 YZF450, WISECO WPC151 YAMAHA KIT
Wiseco Crankshaft Bottom Kit with Bearings and Gaskets. Part number WPC151. Precision-trued to OEM specifications. Connecting rods are double-forged for superior dimensional consistency and grain flow. Shot-peening eliminates residual stresses and smooths 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. Precision-engineered oiling slots maximize rod strength and bearing life. Double-drilled small ends provide extra lubrication and cooling for the piston pin, 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 the rod and washer interface. Crank pin bearings manufactured with high-quality hot-rolled steel, case hardened to 58-62 RC.
