Features

RFX Pro Series Elite Aluminum Sprocket - 420 (Manufacturer part number: FXRS 25-47 99GN): a crown dedicated to motocross, machined for demanding riders. Designed to fit 420 transmissions, it features 47 teeth and a green anodized finish intended to match the compatible Kawasaki KX 85 models.

Construction: CNC machined from 7075 aluminum for a lightweight and precise part.
Profile: CAD-designed to reduce mass while maintaining load geometry.
Dirt Management: mud drainage grooves to limit residue buildup on the chain contact area.
Finish: colored anodization (green), RFX logo laser engraved.
Precision: tight tolerances for consistent chain-sprocket engagement.

Ideal for motocross, this RFX Pro Series Elite sprocket is aimed at owners of KX85 and similar machines looking for an aesthetic, precise part designed for muddy terrain conditions. Before installation, check the torque and chain/sprocket alignment according to manufacturer recommendations.
