Renthal Aluminium Ultra - Light Self - Cleaning Rear 154U - 520 SprocketRef : RT00441A / 1075621024

RENTHAL Ultra-Light Mud-Resistant Sprocket 154U - 520 — designed for demanding motocross, enduro, and roadster riders, this sprocket combines lightness and robustness to refine your machine's transmission.

• Material: precision-machined 7075 T6 aluminum for an excellent weight/strength compromise.
• Mud-resistant tooth profile designed to facilitate dirt evacuation and limit chain fouling.
• Surface anodization to increase surface hardness and enhance appearance (color: purple).
• Strategic cutouts to lighten the part without compromising its strength.
• Technical specifications: 49 teeth, chain pitch 520, standard type.

By replacing an original sprocket with this RENTHAL Ultralight, you reduce the rotational mass at the rear, contributing to better transmission responsiveness and a lively feel during acceleration. The tooth design minimizes unnecessary contact with mud to maintain chain efficiency during muddy outings or in soft terrain.

Suitable for off-road practices (MX, SX, enduro) and favored by riders seeking performance and reliability, this sprocket stands out for its finish and manufacturing technology. Manufacturer reference: 154U-520-49GRPE.
