Features

RENTHAL Ultra-Light Mud-Resistant Sprocket 441U - 428 (50 Teeth)

Designed for motocross and enduro riders seeking lightweight and reliability, the Renthal Ultra-Light 441U sprocket combines highly durable 7075 T6 aluminum with a tooth profile engineered to shed mud. Its precision-machined construction and strategic cutouts reduce weight without compromising mechanical strength, resulting in sharper power delivery and a more responsive bike handling.

Material: 7075 T6 Aluminum, anodized finish for improved surface durability.
Number of Teeth: 50 (pitch 428).
Mud-Resistant Profile: Tooth shape optimized to limit accumulation and reduce chain/sprocket friction.
Weight Reduction: Cutouts made on the sprocket to decrease weight without sacrificing strength.
Type: Standard, suitable for motocross and enduro bikes.

Ideal for muddy terrains and demanding rides, it easily fits 428 setups and is particularly suitable for the small displacement motocross bikes listed below. Manufacturer reference: 441U-428-50GPSI.
