The Renthal Twinring™ Rear Sprocket, part number 1500-520-48GPBK, is engineered for durability and performance with a focus on lightweight design. Crafted from high-strength Ultralight™ 7075 T-6 aluminum for the inner ring, this sprocket offers exceptional strength while maintaining a reduced weight profile. The outer ring is made from electro-less nickel coated steel, providing superior durability and resistance to wear. The manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner ring with an interference fit, combined with a wave pattern that ensures a permanent bond for the life of the chainwheel. The flat socket head screws enhance strength during side impacts and prevent contact with the chain guide, ensuring reliability under demanding conditions. Self-cleaning mud grooves between each tooth facilitate dirt removal, reducing chain and sprocket wear while decreasing overall weight. This sprocket is designed to outlast standard all-aluminum sprockets by a factor of three, offering a longer service life. Despite its robust construction, it remains significantly lighter than traditional all-steel rear sprockets, making it an excellent choice for riders seeking a balance of strength, durability, and weight savings. The black finish adds a sleek aesthetic that complements the Yamaha motorcycle's performance-oriented design. Overall, the Renthal Twinring™ Rear Sprocket provides a high-performance upgrade for riders demanding durability and longevity without compromising weight or functionality.
