CRANKSHAFT BOTTOM KIT KX 80 85 100, WISECO WPC119 KAWASAKI MX
The Wiseco Crankshaft Assembly with Bearings, Seals, and Gaskets offers a complete bottom-end rebuild solution. This assembly is precision-engineered and factory-assembled for superior performance, durability, and reliability. Features include a precision trued assembly to OEM specifications, double-forged connecting rods for consistent dimensions and enhanced grain flow, and a shot-peened surface to reduce residual stresses. It also boasts a corrosion-resistant treatment for protection against wear and environmental damage, case-hardened rod bores for optimized bearing running surfaces, and tuned bearing clearance for maximum performance. Precision honing ensures ultra-round bearing surfaces for consistent reliability, while engineered oiling slots strengthen rods and extend bearing life. Double-drilled small ends improve lubrication and cooling for the piston pin. Silver-coated thrust washers feature a dimpled design to enhance oil retention and reduce friction. Premium caged needle roller bearings are included for high RPM capability. The complete kit contains a top-end bearing (14 x 18 x 17.2 mm), crank pin bearing (22 x 28 x 13.8 mm), main bearings (20 x 52 x 15 mm), thrust washers (2, 22 mm ID x 2 mm), a hollow crank pin (22 mm x 46 mm), and a full bottom-end gasket kit for specific models. Part Number: 56-173.WI.CBK.
