Renthal Twinring™ 48 Tooth Rear Sprocket for Yamaha - Black - Part 1500-520-48GPBK

The Renthal Twinring™ Rear Sprocket, part number 1500-520-48GPBK, offers a high-performance upgrade for Yamaha motorcycles. Crafted with a high strength Ultralight™ 7075 T-6 aluminum inner ring, this sprocket provides exceptional durability while maintaining a lightweight profile. The outer ring is made of electro-less nickel-coated steel, ensuring maximum resistance to wear and corrosion. Designed with minimal material, the outer ring is expanded at 200°C and precisely fitted over the inner ring, creating a permanent and reliable bond through an interference fit and wave pattern. This construction guarantees long-lasting performance even under demanding riding conditions. The flat socket head screws add extra strength, protecting the sprocket during side impacts and preventing contact with the chain guide. Self-cleaning mud grooves between each tooth help reduce dirt accumulation, minimize wear, and keep weight down. This sprocket is engineered to last up to three times longer than standard all-aluminum sprockets, offering a durable yet lightweight solution that is significantly lighter than all-steel alternatives, making it ideal for performance-oriented riders seeking longevity and efficiency.
