RFX Pro Series Elite - Aluminum Sprocket 520 (Manufacturer Part No: FXRS 10-50 99BK)
Designed for off-road use, this RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum for an excellent balance of lightness and strength. Its CAD-optimized design and increased rigidity limit deformation during intense use, while the mud evacuation grooves facilitate maintenance and help preserve the chain and sprocket on the trail.
The sprocket is color-coded according to the brand but is also available in standard silver; this black model is suitable for riders looking for a sleek appearance and a lightweight part. Notable compatibility: Honda CRF 450 R / RWE / RX (2026 - 450 cc). Check the 520 pitch and the number of teeth to ensure compatibility with your drivetrain before installation.
