Features

RFX Pro Series Elite Aluminum Sprocket - 428 (FXRS 51-48 99RD)

Designed for off-road use, the RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum to combine lightweight and strength. Its red anodized finish and laser-engraved RFX logo give it a racing look, while the mud evacuation grooves facilitate self-cleaning in muddy conditions. CAD-modeled profile and tight tolerances ensure a precise fit with the chain for crisp transmission and controlled wear.

Material: CNC machined 7075 aluminum
Number of teeth: 48 (reference 48 teeth)
Chain pitch: 428
Color: anodized red, color code according to model
Mud evacuation grooves to extend chain/sprocket lifespan
Optimized CAD profile for lightweight and rigid design limiting torsion
Laser-engraved RFX logo

Compatible with several 85cc motocross models and other machines equipped with a 428 setup — including KTM 85 SX, Husqvarna TC 85, and GAS GAS MC 85 (listed models). An ideal part for those seeking a robust, precise, and racing-styled sprocket to enhance the transmission of their off-road motorcycle.
