The Renthal Ultralight Rear Sprocket is a high-performance 53-tooth rear sprocket designed for KTM 125-525 EXC, SX, SX-F, XC, XC-W, and XC-F models from 1991 to 2024. It is precision CNC-machined from 7075-T6 aluminum alloy, making it 66% lighter than steel while maintaining exceptional durability. Engineered for motocross, supercross, and enduro racing, this sprocket features an advanced tooth profile for maximum power transfer, improved concentricity, and precise fitment. A combination of a high-strength base material and a specially treated hard-wearing surface significantly extends chainwheel life. Additionally, self-cleaning mud grooves help prevent dirt buildup, ensuring consistent performance in off-road conditions.
