Product Description
The Genuine Royal Enfield Rear Sprocket Adaptor (Part No. 891062) is a vital drivetrain component engineered specifically for the rear wheel assembly of dual-disc Royal Enfield motorcycles. This “Rear Sprocket Drum” acts as the high-precision interface between your rear sprocket and the wheel hub, facilitating the transfer of engine power to the road while maintaining perfect chain alignment.
Manufactured from premium-grade cast aluminum, this adaptor is designed to house the rear sprocket and integrate with the cush drive system. This helps absorb driveline shocks and mechanical harmonics, significantly reducing vibrations and protecting your gearbox from stress during gear shifts. Whether you’re repairing a worn-out hub or upgrading your drivetrain, this authentic factory-original part ensures the durability and fitment quality required for high-torque 350cc and 500cc engines.
