DescriptionRFX Pro Series Elite Aluminium - 428 Sprocket

Product details :

Features

The RFX Pro Series Elite sprocket made of 7075 aluminum is designed for motocross riders seeking to combine lightweight and durability. CNC machined and anodized in black, it features a CAD-optimized profile to reduce mass without sacrificing stiffness. The mud evacuation grooves facilitate cleaning and limit accumulation that can prematurely wear the chain and sprocket.

Material: CNC machined 7075 aluminum
Number of teeth: 49 teeth
Chain pitch: 428 (transmission compatibility)
Finish: black anodization, laser-engraved RFX logo
Design: CAD profile for lightweight, mud evacuation grooves, tight tolerances

The combination of a rigid construction and tight tolerances aims to enhance transmission performance and longevity in off-road conditions. Color-coded according to brands, this black reference pairs particularly well with 85cc competition machines.

Ideal for motocross and off-road use, it is suitable for KTM 85 SX (17/14), Husqvarna TC 85 (17/14), and Gas Gas MC 85 (19/16) models depending on the application. Manufacturer reference: FXRS 51-49 99BK.
