Renthal Ultra-Light Mud-Free Sprocket 441U - 428 (manufacturer part number: 441U-428-49GPPE). Designed for motocross/MX/SX and enduro riding, this sprocket stands out due to its precision-machined 7075 T6 aluminum construction, offering a lightweight and durable component.

• Material: 7075 T6 aluminum, anodized for better surface retention and a durable finish.
• Number of teeth: 49 teeth — 428 chain pitch.
• Mud-Free Profile: Teeth designed to facilitate mud evacuation and reduce friction between the chain and sprocket.
• Weight Reduction: Strategic cutouts to reduce mass without compromising strength.
• Color: Purple — anodized finish.

The geometry and machining of this sprocket help minimize mud accumulation and contribute to smoother transmission on dirty terrains. Its reduced weight aids in lightening the rear of the machine, an appreciated advantage during jumps and directional changes. Compatible with 428 transmissions, it is particularly suitable for small displacement motocross bikes (e.g., KTM 85 SX, GASGAS MC 85, HUSQVARNA TC 85) equipped with the correct gear ratio.

RENTHAL product, a reliable reference for demanding riders looking for a high-performance, lightweight sprocket that is distinctly off-road oriented.
