Renthal Twinring™ Rear Sprocket 51 Tooth for Yamaha 1500-520-51GPSI

The Renthal Twinring™ Rear Sprocket, model 1500-520-51GPSI, offers a high-performance upgrade for Yamaha motorcycles. Crafted with a high-strength Ultralight™ 7075 T-6 aluminum inner ring, it provides exceptional durability while maintaining a lightweight profile. The outer ring is made from electro-less nickel coated steel, ensuring maximum resistance to wear and environmental elements. Designed with minimal material, the outer ring is expanded at 200°C and securely fitted over the inner ring using an interference fit, coupled with a wave pattern for a permanent bond that lasts the life of the chainwheel.
Flat socket head screws reinforce the sprocket's structural integrity during side impacts and prevent contact with the chain guide, enhancing durability. The sprocket features self-cleaning mud grooves between each tooth, which help prevent dirt buildup, reduce wear, and maintain optimal performance. This design not only extends the sprocket’s lifespan—outlasting standard all-aluminum sprockets by three times—but also keeps weight to a minimum, significantly improving acceleration and handling.
Ideal for riders seeking a combination of strength, durability, and lightweight efficiency, the Renthal Twinring™ Rear Sprocket is engineered to withstand demanding riding conditions while providing reliable performance over time. Its advanced construction and materials make it a superior choice for motocross, off-road, and performance-oriented riding applications.
