RENTHAL Ultra-Light Mud-Resistant Sprocket 224U - 520 (53 Teeth)
Designed for demanding riders, the RENTHAL Ultralight 224U combines lightweight construction with durability. Precisely machined from 7075 T6 aluminum, it offers excellent resistance to stress while minimizing the unsprung mass of the rear end — beneficial during traction changes and acceleration.
Whether on a motocross track or an engaged roadster, this sprocket is aimed at riders who want to reduce rotational inertia and limit losses associated with chain/sprocket friction. Compatible with 520 setups, it easily integrates into many machines (e.g., GAS GAS SM 700, KTM 690 SMC R, DUCATI DESMO 450 MX depending on setup). Manufacturer reference: 224U-520-53GPSI.
