Features

RFX Pro Series Elite Aluminum Sprocket - 415 (Manufacturer Part No: FXRS 57-42 99BU)

Designed for off-road use, this RFX Pro Series Elite sprocket is CNC machined from high-performance 7075 aluminum and anodized in blue. Its 42-tooth configuration with a 415 pitch is aimed at small displacement motocross bikes and minimotos, offering a lightweight design with a CAD profile while maintaining a rigid construction to limit torsion under load.

Integrated mud evacuation grooves facilitate self-cleaning around the chain/sprocket contact area, reducing debris buildup and contributing to more consistent wear of the chain and sprocket. The RFX logo is laser-etched for a durable and neat finish.

Material: CNC machined 7075 aluminum
Number of teeth: 42 (415 pitch)
Color: anodized blue (also available in silver)
CAD profile for lightweight and tight tolerances
Mud evacuation grooves for longevity
Laser-etched RFX logo

Universe: Motocross. Compatible models (top 3): KTM 50 SX (2025), HUSQVARNA TC 50 (2025), GAS GAS MC 50 (2025).
