Description
The Renthal Twinring Rear Sprocket is designed for 1999-2024 Yamaha YZ125, YZ250, YZ450F, WR250F, and WR450F models. This 50-tooth, 520-pitch sprocket features a dual-material construction, combining a hardened steel outer ring with an ultralight aluminum inner ring. The steel outer is heated to 200°C before being permanently bonded to the aluminum core, ensuring durability while maintaining a lightweight design. Engineered for maximum longevity and performance, the Twinring sprocket reduces unsprung weight without compromising power delivery, making it ideal for motocross and enduro riders who want to spend more time riding and less time on maintenance.
