Product details :

Features

RENTHAL Ultra-Light Mud-Resistant Sprocket 441U - 428 (47 Teeth)

Designed for off-road competition, this Renthal Ultra-Light sprocket combines lightweight construction with durability for heavy terrain. Precisely machined from 7075 T6 aluminum, it features a specific mud-resistant profile and strategic cutouts that limit mud accumulation without sacrificing structural strength.

Material: Anodized 7075 T6 aluminum (silver finish).
Teeth: 47 teeth, 428 chain pitch (manufacturer reference 441U-428-47GPSI).
Design: Optimized tooth profile to facilitate mud evacuation and reduce friction between chain and sprocket.
Weight Reduction: Machined cutouts at key points to decrease mass while maintaining the rigidity needed for jumps and accelerations.
Finish: Surface anodization for improved abrasion resistance and lasting aesthetics.

Ideal for motocross, supercross, and enduro, this sprocket is aimed at riders seeking responsive transmission and better mud evacuation on special stages. Common compatibilities: KTM 85 SX (17/14), GAS GAS MC 85 (19/16), Husqvarna TC 85 Big Wheels (19/16) — check fitment before installation.
