Renthal Twinring™ Rear Sprocket - 49 Tooth - Black for Yamaha 1500-520-49GPBK

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 premium Ultralight™ 7075 T-6 aluminum, the same material used in standard Renthal sprockets, it provides exceptional strength while maintaining a lightweight profile. The outer ring is constructed from electro-less nickel-coated steel, ensuring maximum durability and resistance to wear. Designed with minimal material, the outer ring is expanded at 200°C and fitted over the inner ring through an interference fit, which, combined with a wave pattern, creates a permanent bond that lasts for the life of the chainwheel. This innovative manufacturing process enhances longevity and reliability, even under demanding riding conditions. Flat socket head screws reinforce the sprocket during side impacts and prevent contact with the chain guide, further improving its robustness. The inclusion of self-cleaning mud grooves between each tooth helps prevent dirt accumulation, reducing wear and weight while ensuring smooth operation. This sprocket is engineered to last up to three times longer than standard all-aluminum sprockets, providing a significant upgrade for riders who demand durability without sacrificing weight savings. Its design balances strength, weight, and longevity, making it an excellent choice for off-road and motocross applications where performance matters. The black finish adds a sleek aesthetic that complements a variety of motorcycle styles while providing additional corrosion resistance. Whether replacing a worn sprocket or upgrading for improved performance, the Renthal Twinring™ Rear Sprocket is engineered to meet the rigorous demands of motorcycle racing and trail riding alike.
