CG125 motorcycle override clutch single plate starter plate body one-way transmission plate

The CG125 clutch disc exceeds the original specifications, strictly replicating the CG125 factory standards. The internal teeth, positioning holes, and crank/starting gear match 100%, allowing direct replacement of old parts without modification. Made from 45# carbon steel with precision machining, its surface is quenched and blackened for rust prevention, reaching a hardness of HRC40-45, making it wear-resistant and impact-resistant with a lifespan twice that of ordinary materials. It features a built-in 3-ball pawl structure, ensuring precise engagement depth (tooth gap ≤0.1mm), delivering seamless power transfer during starting, and automatically disengaging after engine operation to prevent damage to the starting mechanism. CNC machining guarantees internal bore and tooth profile tolerances ≤0.02mm, with a smooth, burr-free surface, allowing smooth rotation without stiffness after installation, and noise ≤45dB. Dual protection with black coating and rust-prevention oil, salt spray test ≥48 hours, resisting rust and corrosion even when exposed to humid or oily environments for extended periods.
