Renthal Twinring™ 49 Tooth Rear Sprocket for Yamaha - Blue - Part 1500-520-49GPBU

The Renthal Twinring™ Rear Sprocket offers a high-performance upgrade for Yamaha motorcycles, combining durability with lightweight design. Crafted with an inner ring made from premium Ultralight™ 7075 T-6 aluminum, this sprocket ensures strength while minimizing weight. The outer ring is constructed 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, creating a permanent bond that withstands rigorous riding conditions. The wave pattern design further enhances longevity by distributing stress evenly across the sprocket.
Self-cleaning mud grooves between each tooth prevent dirt accumulation, reducing chainwheel wear and maintaining optimal performance during muddy or dusty rides. The flat socket head screws reinforce the sprocket's integrity during side impacts and prevent contact with chain guides, ensuring reliable operation. This design results in a sprocket that lasts up to three times longer than standard all-aluminum counterparts, yet remains significantly lighter than traditional steel sprockets.
Whether you're racing or trail riding, the Renthal Twinring™ 49 Tooth Rear Sprocket delivers exceptional strength, durability, and weight savings, making it an ideal choice for demanding riders seeking longevity and performance in a sleek, blue finish.
