The Renthal Twinring™ Rear Sprocket offers a high-performance solution for motorcycle enthusiasts seeking durability and lightweight design. Crafted with an inner ring made from ultralight 7075 T-6 aluminum, the same high-strength material used in Renthal's standard sprockets, this sprocket provides exceptional strength without adding unnecessary weight. The outer ring is constructed from electro-less nickel coated steel, ensuring maximum durability and resistance to wear in demanding riding conditions. The outer steel ring is expanded at 200°C and fitted over the inner ring using an interference fit, combined with a wave pattern that guarantees a permanent bond for the lifespan of the chainwheel. This innovative manufacturing process enhances the sprocket's structural integrity and longevity.
Flat socket head screws are included to add extra strength during side impacts and prevent contact with the chain guide, improving overall reliability. The sprocket features self-cleaning mud grooves between each tooth, designed to prevent dirt buildup, reduce wear, and keep weight to a minimum. Built to outperform standard all-aluminum sprockets by a factor of three, this design also remains significantly lighter than traditional all-steel sprockets, delivering a balanced mix of durability and agility. Ideal for riders who demand long-lasting performance and reduced weight, the Renthal Twinring™ Rear Sprocket is a trusted choice for Yamaha models and other compatible motorcycles. Its robust construction and thoughtful design make it a valuable upgrade that enhances drivetrain efficiency and longevity in various riding conditions.
