RFX Pro Series Armalite 520 Sprocket — Ref. FXRS 80-50 ALBU

Designed for motocross competition, the RFX Armalite composite sprocket combines lightweight and strength. Its core is machined from 7075-T6 aluminum to minimize unsprung weight, while the outer ring is made from high-density carbon HCS steel to ensure the longevity of the teeth. The dual-ring mounting reduces stress on the rivets and provides enhanced stability in demanding conditions.

• Type: Dual sprocket (Armalite) - pitch 520
• Teeth: 50
• Material: CNC 7075 aluminum inner ring, HCS outer ring
• Finish: Blue anodization
• Technology: Hex-Drive interface between rings for optimized transmission
• Design: Lightweight CAD profile, mud evacuation grooves, and rigid structure against torsion

Ideal for riders seeking a durable and lightweight sprocket without compromising reliability. Compatible with several TM RACING models (MX 530 FI 2022, EN 530 FI ES 2022, MX 450 FI 2022). Follow the manufacturer's recommendations for installation and torque; the hexagonal interface requires uniform tightening to ensure perfect transmission between the two rings.
