RENTHAL Ultra-Light Mud-Resistant Sprocket 154U - 520 — designed for demanding motocross, enduro, and roadster riders, this sprocket combines lightness and robustness to refine your machine's transmission.
By replacing an original sprocket with this RENTHAL Ultralight, you reduce the rotational mass at the rear, contributing to better transmission responsiveness and a lively feel during acceleration. The tooth design minimizes unnecessary contact with mud to maintain chain efficiency during muddy outings or in soft terrain.
Suitable for off-road practices (MX, SX, enduro) and favored by riders seeking performance and reliability, this sprocket stands out for its finish and manufacturing technology. Manufacturer reference: 154U-520-49GRPE.
