RENTHAL Ultra-Light Mud-Resistant Sprocket 150U - 520 (manufacturer part number: 150U-520-44GBSI)

Designed for motocross, the Renthal Ultra-Light 150U sprocket is machined from 7075 T6 aluminum, an alloy known for its strength-to-weight ratio. Its specific tooth profile facilitates mud evacuation and minimizes chain fouling, making it useful in wet or muddy terrains.

• Material: 7075 T6 aluminum, surface anodization
• Number of teeth: 44 — chain pitch: 520
• Mud-resistant design with strategic cutouts to reduce weight without compromising rigidity
• Precision machining for optimized chain/sprocket contact
• Color: silver — type: standard

The anodized finish hardens the surface while protecting aesthetics. The combination of fine machining and an appropriate tooth profile aims to reduce unnecessary friction between the chain and sprocket, benefiting the responsiveness of the transmission and the longevity of the driven components.

Ideal for MX, SX, and enduro disciplines, this sprocket is aimed at riders looking to reduce weight without sacrificing strength. Compatible with models such as YAMAHA YZ 450 F (2026), FANTIC XX 125 (2022), and YAMAHA WR 450 F (2026) according to the 520 pitch and number of teeth. Always check compatibility with your machine before installation.
