Description
The Renthal Ultralight Rear Sprocket is designed for high-performance motocross, supercross, and enduro riding. Precision CNC-machined from 7075-T6 aluminum, this sprocket is 66% lighter than steel while maintaining exceptional durability. Its advanced tooth profile enhances power transfer and extends chain life. Engineered for a precise fit, it ensures optimal load distribution and concentricity. The hard-anodized surface increases wear resistance, while self-cleaning mud grooves help prevent dirt buildup for consistent performance. This 520-pitch, 50-tooth sprocket is compatible with KTM 125-525 EXC, SX, SX-F, XC, XC-W, and XC-F models from 1991 to 2024.
