RFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 SprocketRef : RFX00410A / 1123236004

RFX Pro Series Armalite Sprocket 49 Teeth – 520 (FXRS 50-49 ALBU)

Designed for demanding riders, this Armalite composite sprocket combines a machined 7075-T6 aluminum inner ring and a high carbon density HCS steel outer ring. The "double ring" mounting reduces rotor weight while maintaining the strength of the teeth, and the Hex-Drive interface between the two parts eliminates the stress transmitted to the rivets.

• Compatibility: 520 pitch chain, 49 teeth — suitable for quad, motocross, and roadster.
• Materials: CNC 7075 aluminum center, HCS steel outer ring.
• Finish: durable blue anodization for a neat look and corrosion protection.
• Design: optimized CAD profile, mud release grooves, and increased torsional rigidity.

This sprocket is aimed at users looking to lighten the drivetrain without sacrificing tooth longevity. Installation requires standard tools and adherence to the manufacturer's torque specifications: clean the hub, apply thread-locking compound to the screws, and tighten in a cross pattern for even fastening.

Manufacturer reference: FXRS 50-49 ALBU — blue, 49 teeth, 520.
