RENTHAL Ultra-Light 150U - 520 Sprocket (46 teeth)
Specifically designed for motocross, the Renthal Ultra-Light 150U sprocket combines lightweight construction and durability. Machined from 7075 T6 aluminum, it features a mud-resistant tooth profile that facilitates dirt evacuation and limits accumulation between the chain and sprocket, ensuring a smoother transmission even in muddy conditions.
The hardened anodization enhances surface durability and appearance, while strategic cutouts reduce weight without compromising strength. This optimization lightens the rear of the motorcycle, contributes to better transmission responsiveness, and increases the longevity of the part. Ideal for MX, SX, and enduro, it is compatible with YAMAHA YZ 450 F (2026), FANTIC XX 125 (2022), and YAMAHA WR 450 F (2026) equipped with 520.
