YZ125 2005 - 2020,

Wiseco Crankshaft w/Bearings and Gaskets - WPC163,

��Precision-trued to OEM specifications and factory assembled
��Shot-peening eliminates residual stresses and smoothly blends the rod forging surfaces
��Corrosion-resistant surface treatment
��Crank pin bearing radial running clearance is optimized to ensure maximum performance
��Precision honing ensures ultra-round bearing surface
��Precision-engineered oiling slots maximize rod strength and bearing life
��Double-drilled small ends provide the piston pin with extra lubrication and cooling, reducing distortion of top end 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 hot-rolled steel -- case hardened to 58-62 RC
��Caged needle roller bearings provide the highest possible RPM
��Precision-machined crank webs
��Crankshaft comes with top-end bearing and gasket
