The Royal Enfield Genuine Stopper Assy Shift (Part No. 570658/D) is a precision-engineered internal gearbox component designed for the Unit Construction Engine (UCE) platform. This assembly is a critical part of the gear shifting mechanism, responsible for indexing and “stopping” the gear drum at the correct position for each gear change.
the assembly features a spring-loaded arm with a roller or specialized tip that engages with the gear shift drum. This ensures that every gear shift is crisp, positive, and stays securely in place without “jumping” out of gear or falling into a false neutral. Using the genuine 570658/D stopper is vital for maintaining smooth transmission performance and preventing long-term damage to the gear teeth.
