Features

RFX Pro Series Elite Aluminum Sprocket - 420 (Manufacturer Ref: FXRS 25-44 99GN)

Specifically designed for motocross, this RFX Pro Series Elite sprocket combines lightweight construction with durability. CNC machined from 7075 aluminum and anodized in green, it features 44 teeth with a 420 pitch to fit the drivetrains of small displacement off-road bikes. Its face is laser-engraved with the RFX logo for a polished finish.

The mud evacuation grooves and CAD profile reduce dirt accumulation and contribute to the longevity of the chain and sprocket. The rigid design limits torsional deformation while the tight tolerances optimize tooth engagement, which is beneficial during corner exits or in technical sections.

Material: CNC machined 7075 aluminum
Number of teeth: 44
Chain pitch: 420
Color: Anodized green
Type: Standard, color code by brand

Compatibility (examples): Kawasaki KX 85 II (2026), Kawasaki KX 85 I (2026), KAWASAKI KX 85 STD WHEELS 17/14 (2021). An ideal part for those seeking a lightweight, durable, and easy-to-maintain sprocket for muddy terrains.
