Renthal Ultra-Light Mud-Resistant 441U - 428 (47 Teeth) - Blue

Designed for motocross and enduro competition, the Renthal Ultralight 441U sprocket combines lightweight construction with durability. Machined from 7075 T6 aluminum, it features a surface anodization to harden the material and protect its aesthetics. Its specific tooth profile facilitates mud evacuation and limits dirt retention between the chain and the sprocket.

The machined cutouts and Ultralight design help to decrease transmission inertia, promoting better acceleration responsiveness.
