Aluminium Mud-Resistant Sprocket 520 53 Teeth by Renthal
UltraLight sprocket made from CNC machined 7075 T6 aluminium, designed for motocross use and precise fitting on the 520 transmission. Its tight tolerance manufacturing ensures concentricity and optimised tooth profiling for effective power transfer. The surface treatment enhances wear resistance during intensive use.
Design and Materials
- CNC machined 7075 T6 aluminium from Manchester for dimensional precision and reliable fitting on the sprocket carrier
- 66% lighter than steel, significantly reducing the mass of the part compared to a steel sprocket
- Tooth profiling and load distribution designed for effective power transfer between engine and chain
Practicality and Features
- Wear-resistant surface treatment to maintain tooth geometry during intensive use
- Extremely tight tolerances ensuring concentricity and minimising play for consistent transmission behaviour
Advantages
- Designed for motocross, suitable for off-road conditions
- OEM Reference 522U-520-53GPBK
