Features

RFX Pro Series Elite Aluminum Sprocket - 428 (Manufacturer part number: FXRS 51-50 99OR)

Designed for motocross, this RFX Pro Series Elite sprocket is CNC machined from high-strength 7075 aluminum. Its CAD-optimized profile and orange anodization give it a race-ready look while minimizing unsprung weight. The mud evacuation grooves facilitate cleaning in muddy terrain and contribute to the longevity of the chain and sprocket.

Material: CNC machined 7075 aluminum
Number of teeth: 50 teeth (sprocket)
Chain pitch: 428
Finish: Orange anodized, laser-etched RFX logo
Design: Lightweight CAD profile, anti-mud grooves, and tight tolerances

The rigid design of the sprocket aims to improve torsional resistance while maintaining geometry true to the original drivetrain. Color-coded according to brands, it is also available in silver to fit different models. Ideal for motocross riders and intensive training.

Compatibility (examples): KTM 85 SX STD WHEELS 17/14 (2025), HUSQVARNA TC 85 STD WHEELS 17/14 (2025), GAS GAS MC 85 19/16 (2025).
