RFX Pro Series Elite Aluminum Sprocket - 420: designed for off-road and motocross competition, this RFX sprocket combines lightness and strength for reliable transmission on muddy terrains. CNC machined from 7075 aluminum, it features an optimized CAD profile to reduce weight while maintaining rigidity suited to chain stresses.
- Material: CNC machined 7075 aluminum
- Number of teeth: 54 teeth (54)
- Chain pitch: 420
- Color: Anodized red (manufacturer code)
- Technical features: mud evacuation grooves, laser-etched RFX logo, tight tolerances

The evacuation grooves limit mud accumulation between the teeth and the chain, thus extending the useful life. The rigid design and reduced tolerances contribute to better torque handling and more precise interaction with the sprocket. Color-coded according to motorcycle models, this sprocket is also available in standard silver finish.
