DescriptionRFX Pro Series Elite Aluminium - 420 Sprocket

Product details :

Features

Manufacturer Reference: FXRS 56-50 99BU

The RFX Pro Series Elite aluminum sprocket is a piece designed for the terrain. CNC machined from 7075 aluminum, it combines strength and low mass to limit unsprung weight and maintain the responsiveness of the transmission. The mud evacuation grooves facilitate clearance during muddy outings and contribute to more uniform wear of the chain and sprocket.

Material: CNC machined 7075 aluminum
Number of teeth: 50 (optimized CAD profile)
Chain pitch: 420
Finish: Blue anodization, laser-engraved RFX logo
Design: lightweight CAD profile, rigid design to reduce torsion
Tolerances: precise machining for improved chain engagement
Usage: specially suited for motocross riding

Color-coded according to brands and available in different shades, this RFX Pro Series Elite sprocket easily integrates with 420 transmissions of small displacement motocross bikes. Examples of applications: KTM 65 SX (2022, 2023) and KTM 60 SX (2000). This part is aimed at riders looking for a high-performance and durable sprocket for their off-road sessions.
