- Specially designed side scalloping vent slots on large end to maximize rod bearing lubrication
- Includes connecting rod, crank pin, crank pin bearing, thrust washers, and wrist pin bearing for two strokes
Hot Rods are double forged to improve grain flow and maintain dimensional consistency. They're shot peened to eliminate surface stress risers and to smoothly blend the rod forging's radiuses together, which produces more consistent dimensioning and surface finish for superior strength under heavy loads, unlike hand ground and polished rods. By shot peening the connecting rod's surface, fatigue durability is improved two times over a un-peened forged rod, and over eight times, compared to a polished rod. Double honing produces an ultra round bearing surface (50 millionths tolerance), producing a reliable high RPM connecting rod. Small ends are double drilled to supply extra lubrication and cooling to the wrist pin and bearing. Uniquely big end design uses strategically located side scalloping and vent slots to minimize high RPM bearing race distortion. Fits Yamaha 2006-2012 YFZ450.
