RFX Pro Series Armalite 520 Sprocket - Manufacturer Reference: FXRS 50-51 ALBU

Designed for quad, motocross, and roadster enthusiasts seeking durability and precision, this Armalite composite sprocket combines a machined center made from 7075-T6 aluminum with a high-density carbon steel outer ring. The result: a rigid construction that limits torsional deformation while reducing unsprung mass.

• Number of teeth: 51 (pitch 520) — perfect for balanced engine performance and good chain retention.
• CNC 7075 aluminum center for high alignment precision.
• HCS (high carbon steel) outer ring for improved tooth longevity.
• Hex-Drive interface between inner and outer rings that maximizes power transfer and reduces stress on the rivets.
• Lightweight CAD profile and optimized mud evacuation grooves to limit buildup and wear.
• Blue anodized finish for protection and a racing look.

Product ready to be mounted according to standard procedures: lift the rear wheel, remove chain and wheel, position the sprocket, apply suitable Loctite to the bolts, and tighten evenly to the torque specified by the manufacturer. A durable replacement part for those looking to enhance reliability and transmission behavior.
