Renthal Twinring™ 50-Tooth Rear Sprocket for Honda – Durable Ultralight Aluminum and Steel Construction

The Renthal Twinring™ Rear Sprocket, part number 1540-520-50GPRD, is engineered for high-performance motorcycles requiring a combination of strength and lightweight design. Crafted with an inner ring made from high-strength Ultralight™ 7075 T-6 aluminum, this sprocket offers exceptional durability while maintaining a significantly reduced weight for optimal acceleration and handling. The outer ring, constructed from electro-less nickel coated steel, provides maximum wear resistance and longevity, ensuring reliable operation over extensive riding miles. The manufacturing process involves expanding the steel outer ring at 200°C and fitting it over the aluminum inner ring with an interference fit, complemented by a wave pattern that guarantees a permanent bond for the lifespan of the chainwheel. This innovative bonding technique ensures the sprocket withstands impacts and heavy loads without compromise. The flat socket head screws enhance the sprocket’s structural integrity during side impacts and prevent contact with the chain guide, contributing to overall durability. Features such as self-cleaning mud grooves between each tooth help prevent dirt accumulation, reducing wear and weight while maintaining smooth chain operation. This sprocket is designed to last three times longer than standard all-aluminum options, yet it remains much lighter than traditional steel sprockets, providing an ideal balance of strength and weight savings for competitive and recreational riding. The distinctive red finish adds a stylish touch, complementing various motorcycle aesthetics while offering reliable performance for demanding riding conditions.
