Renthal Aluminium Ultra-Light Self-Cleaning 141U - 520 SprocketRef : RT00079A / 1075616002

Renthal Ultra-Light 141U-520-41GPSI — mud-resistant aluminum sprocket designed for competition. Precisely machined from 7075 T6 aluminum, this sprocket combines lightweight and durability for muddy motocross, SX, and enduro sessions.

• Optimized mud-resistant profile: tooth design engineered to facilitate mud evacuation and minimize chain snagging.
• Construction: 7075 T6 aluminum, surface anodization for improved abrasion resistance and a polished silver finish.
• Targeted weight reduction: strategic cutouts to reduce mass without compromising strength.

With its 41 teeth and 520 pitch, this standard sprocket fits on compatible 520 transmissions and provides a more responsive feel to the rear end without compromising durability. Its profile minimizes power loss due to chain/sprocket friction in dirty conditions.

Ideal for riders looking to gain responsiveness and reliability on muddy terrains. Manufacturer reference: 141U-520-41GPSI. Examples of frequently equipped machines: VERTIGO NITRO WORKS 300, GAS GAS TXT 300 RACING, BETA EVO 300 2T SS (check compatibility based on installation and year).
