Steel Mud-Resistant Output Sprocket 520 13 Teeth by Renthal
This output sprocket is designed for motocross use, made from cemented nickel-chrome-molybdenum steel with a refined core for an excellent balance of strength and hardness. The ULTRALIGHT machining reduces rotational mass for a more responsive engine, while the GROOVED cutouts facilitate mud evacuation to maintain chain engagement.
Design and Materials
- Cemented nickel-chrome-molybdenum steel with a refined core providing strength and hardness for enhanced durability.
- ULTRALIGHT machining eliminates excess material to reduce rotational mass and improve acceleration responsiveness.
Practicality and Features
- GROOVED: cutouts under the tooth allowing mud evacuation to maintain consistent contact between the chain and the sprocket.
- Drainage cutouts preventing mud from exerting additional tension on the chain, thus limiting premature wear.
Benefits
- Designed for motocross, suitable for muddy conditions and off-road demands.
- OEM Reference 523U-520-13GP
- Designed for 520 chain, compatible with transmissions using this chain pitch.
