RFX Pro Series Armalite 520 Sprocket — Manufacturer Ref: FXRS 50-49 ALOR

Designed for demanding riders in motocross, quad, or roadster, this RFX Pro Series Armalite composite sprocket combines lightweight and durability. It features a dual-ring construction: a CNC-machined core made from 7075-T6 aluminum to reduce unsprung mass, and an outer ring made from high carbon steel (HCS) to ensure the longevity of the teeth.

• Type: dual-ring composite — aluminum + HCS
• Number of teeth: 49 (chain pitch 520)
• Hex-Drive interface between inner and outer ring for optimized transmission and reduced stress on the rivets
• CAD profile to optimize mass and rigidity
• Redesigned mud grooves to minimize wear in off-road conditions
• Orange anodized finish — racing look and corrosion protection

On the track as well as on the road, this sprocket reduces rotational mass while providing a tooth area resistant to abrasion. It is aimed at users who want durable, easy-to-maintain equipment compatible with 520 transmissions. Ideal for optimizing agility and engine torque response without compromising strength.

Installation Tips: clean the hub, position the sprocket, use blue Loctite on the bolts, and tighten to the torque specifications provided by the manufacturer. Check alignment and chain tension after installation.
