Features

RFX Pro Series Elite Aluminum Sprocket - 428 (Manufacturer Part No: FXRS 51-49 99RD)

Designed for off-road use, the RFX Pro Series Elite sprocket combines lightweight and durability thanks to its CNC-machined 7075 aluminum construction. Its CAD profile optimizes material to reduce weight without compromising stiffness, while the red anodization provides a racing look and wear protection.

Material: CNC-machined 7075 aluminum
Number of Teeth: 49 teeth (sprocket)
Chain Pitch: 428
Finish: red anodized with laser-engraved RFX logo
Design: CAD profile, tight tolerances
Terrain Maintenance: mud evacuation grooves to extend chain/sprocket lifespan
Type: standard, specific color code per model

Ideal for motocross and intensive training, this sprocket is particularly suited for recent 85cc models. Common compatibilities include KTM 85 SX STD WHEELS 17/14 (2025), HUSQVARNA TC 85 STD WHEELS 17/14 (2025), and GAS GAS MC 85 19/16 (2025). For riders looking for a lightweight, precise part designed for muddy conditions, the RFX Pro Series Elite is a reliable and aesthetic option.
