WWPC153 Crankshaft Kit KTM EXC125 2009 2014

Features: Crankshafts are factory assembled and precision trued to OEM specifications. Double-forged Wiseco connecting rods maintain superior dimensional consistency through improved grain flow. 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. Kit includes crankshaft assembly, main bearings, and bottom-end gasket kit. Kit Includes: • Crankshaft Assembly • Bottom End Gasket #WB1170 • Main Bearing #B5039/B5046.
