Product details :

Features

RENTHAL Ultra-Light Mud-Resistant Aluminum Sprocket 441U - 428 (48 Teeth) — Ref. 441U-428-48GPSI

Designed for off-road riders, this Renthal Ultralight™ sprocket combines lightweight construction with durability. Machined from 7075 T6 aluminum, it offers excellent mechanical strength while minimizing unsprung weight. The specific tooth profile facilitates mud evacuation and reduces friction between the chain and sprocket, thereby helping to limit power losses due to friction.

Material: 7075 T6 aluminum, surface anodization to harden and protect the part
Number of Teeth: 48
Chain Pitch: 428 (suitable for 428 transmissions)
Finish: silver
Design: mud-resistant profile + strategic cutouts for weight reduction without compromising strength
Type: standard, designed for Cross / MX / SX / Enduro

Ideal for those looking to reduce rotating mass and improve transmission smoothness on muddy terrains. Check compatibility with your model and front sprocket before installation. Examples of frequently mounted models:

KTM 85 SX STD WHEELS 17/14 (2026 - 85 cc)
GAS GAS MC 85 19/16 (2026 - 85 cc)
HUSQVARNA TC 85 BIG WHEELS 19/16 (2025 - 85 cc)
