Features

RFX Pro Series Elite Sprocket - 415 (39 teeth) - Ref. FXRS 57-39 99RD

Designed for off-road use, this RFX Pro Series Elite sprocket in red aluminum combines lightweight and durability. CNC machined from 7075 aluminum, it features an optimized CAD profile and tight tolerances for precise tooth geometry. The mud evacuation grooves limit dirt accumulation to preserve the lifespan of the chain and sprocket during muddy outings.

Material: CNC machined 7075 aluminum
Number of teeth: 39 (chain pitch 415)
Finish: red anodization, laser-etched RFX logo
CAD profile for weight reduction and increased rigidity
Mud evacuation grooves for better longevity in off-road conditions
Type: standard, optimized machining tolerances

Ideal for small displacement motocross bikes and demanding riders on track or trail. Reference suitable for recent 50 cc models such as KTM 50 SX (2025), HUSQVARNA TC 50 (2025), and GAS GAS MC 50 (2025). Please check the chain pitch and number of teeth of your setup before purchase to ensure perfect compatibility.
