Product Specification
motorcycle crankshaft is a precision-engineered rotating component that serves as the mechanical backbone of the internal combustion engine, converting the reciprocating linear motion of the piston into rotational torque to drive the transmission and rear wheel. Manufactured from high-strength forged alloy steel—typically 40Cr or 42CrMo grades—with hardness ratings of 48–58 HRC and tensile strengths reaching up to 1080 MPa, this critical component delivers exceptional fatigue resistance, wear resistance, and dimensional stability under extreme rotational speeds and mechanical stress. Designed for commuter motorcycles, leisure bikes, racing machines, and custom-built applications, the crankshaft ensures smooth acceleration, efficient power transmission, and long-term reliability across diverse riding conditions.
