RFX Pro Series Elite Aluminum Sprocket - 520 (manufacturer's reference: FXRS 60-48 99BU): a sprocket designed for both the track and casual rides. CNC machined from 7075 aluminum and anodized blue, it features a CAD-optimized profile to reduce weight without sacrificing rigidity. The mud evacuation grooves are designed to clear dirt and limit accumulation between the teeth and chain, making maintenance easier in muddy or dusty conditions.
Designed for 520 pitch transmissions, this 48-tooth sprocket combines tight tolerances and a reinforced structure for better torque transmission and increased resistance to twisting. The RFX logo is laser-etched for a clean and durable finish. Available in brand-specific color codes, it easily integrates onto both motocross and roadster machines.
Exemplary compatibility: Sherco 300 SEF‑R Factory, Beta RR 480 4T, Gas Gas EC 250 Racing Six Days — ideal for those seeking reliability and a technical look for their transmission.
