Renthal Front Sprocket - Grooved, 13-Tooth for Honda CRF250R/RX (501U-520-13GP)

The Renthal 501U-520-13GP front sprocket is designed for Honda CRF250R and CRF250RX motorcycles requiring dependable drivetrain performance. This grooved, 13-tooth sprocket is CNC-machined from case-hardened and core-refined 655M13 nickel chromium steel, providing a strong foundation for demanding motocross, off-road, and racing applications.
Self-cleaning mud grooves are machined at each tooth to help prevent mud and debris buildup during challenging riding conditions. By reducing material accumulation around the teeth, the sprocket helps maintain consistent chain engagement and supports improved wear resistance. The tooth profile is engineered for reliable power transfer and long-lasting performance when paired with a compatible chain and rear sprocket.
The ultralight design provides a 10–15% weight savings compared with conventional sprockets, helping reduce rotating mass without sacrificing the durability expected from Renthal components. The Renthal 501U-520-13GP offers a practical combination of low weight, high-strength construction, and mud-shedding performance for riders seeking a purpose-built replacement or race-ready upgrade for their Honda CRF250R/RX.
