Manufacturer Reference: FXRS 10-49 99ST

The RFX Pro Series HCS 49-tooth sprocket is designed for demanding motocross and enduro riders who want reliability and longevity without breaking the bank. Made from certified high-carbon steel, it offers excellent wear resistance while maintaining an optimized profile to limit mass compared to standard sprockets. Its silver finish and CNC laser cutting ensure a precise fit and tight tolerances for consistent transmission performance.

Engineered using CAD, the sprocket features mud evacuation grooves to reduce abrasion in muddy terrains. The rigidity of its design enhances torsional stability, which is beneficial during aggressive rides or sudden cornering. Compatible with 520 chains, it follows a standard pitch and has appropriate drilling for common mounts.
