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

Upgrade your Honda CRF250R or CRF250RX with the Renthal 501-520-13GP Grooved Front Sprocket. Designed for demanding motocross and off-road riding, this 13-tooth sprocket combines precision CNC machining with durable nickel chromium steel construction to provide dependable drivetrain performance and long-lasting wear resistance.
The sprocket is CNC-machined from case-hardened and core-refined 655M13 nickel chromium steel. This specialized material and manufacturing process create a strong, durable component engineered to withstand the loads and conditions associated with high-performance motorcycle use. The precisely formed tooth profile supports smooth chain engagement and consistent power transfer.
Self-cleaning mud grooves are machined into each tooth to help prevent mud and debris from building up between the sprocket and chain. By reducing contamination in the contact area, the grooves help maintain reliable operation and increase resistance to premature wear during muddy or off-road conditions. Renthal’s ultralight design also reduces weight by approximately 10–15 percent compared with conventional sprocket designs, helping minimize rotating mass without sacrificing durability.
The Renthal 501-520-13GP is a practical replacement or performance-focused upgrade for riders seeking a lightweight, durable front sprocket for compatible Honda CRF250R and CRF250RX applications. Verify motorcycle model year and fitment before installation, and replace the chain and rear sprocket when necessary to promote even drivetrain wear.
