Product details :

Features

Manufacturer Ref: FXRS 35-52 99BK — RFX Pro Series Elite Aluminum Sprocket (428)

Designed for motocross, this RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum for an optimized weight/stiffness compromise. Its anodized black finish ensures durability and a racing look, while the laser-etched RFX logo marks the piece. Suitable for 428 pitch chains, it features 52 teeth for precise power transmission on demanding terrains.

Material: CNC machined 7075 aluminum
Number of teeth: 52
Chain pitch: 428
Finish: black anodization, laser-etched logo
Design: lightweight CAD profile and rigid construction to limit torsion
Terrain maintenance: mud evacuation grooves to protect the chain and sprocket
Color codes: available according to motorcycle brand or in standard silver

Tight tolerances ensure smoother chain engagement, which is useful in motocross where every change in speed matters. Suitable for the listed 85cc models (YAMAHA YZ 85, YZ 85 LW Big Wheels, SUZUKI RM 85), and for any equipment accepting a 428 sprocket with 52 teeth.
