Features
The RFX Pro Series HCS 520 sprocket (48 teeth) is designed for motorcyclists and off-road riders seeking a robust and accessible component for their drivetrain. Machined from high-carbon steel, it combines durability against wear with an optimized profile to limit excess weight compared to aluminum solutions — a pragmatic choice for trail, motocross, or roadster machines.
- Material: certified high-carbon steel for better wear resistance.
- Cutting: CNC laser for tight tolerances and a precise fit on the hub.
- Profile: designed using CAD to lighten the part without sacrificing rigidity.
- Protection: mud evacuation grooves to limit accumulation and premature wear.
- Specifications: 48 teeth, pitch 520, silver finish.
Simple installation for a knowledgeable amateur mechanic: clean the hub, position the sprocket, grease/modification of the fasteners according to the manufacturer's recommendations, and respect the torque settings. The use of thread-locking compound and final checking of alignment and chain tension are recommended for optimal longevity.
Common applications: quad, motocross, and roadster. Examples of compatible machines: TRIUMPH TF 450-X (2026), DUCATI DESMO 450 MX (2026), STARK FUTURE VARG EX (2026).
