RFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 SprocketRef : RFX00505A / 1123248003

Manufacturer's ref: FXRS 80-51 ALBU

The RFX Pro Series Armalite 520 sprocket is designed for motocross and off-road use: it features a double-ring composite construction, a machined center made of 7075-T6 aluminum, and an outer ring made of high carbon steel (HCS). This aluminum/steel combination offers a weight/strength compromise suitable for soft terrain and jumping phases where every gram counts.

• Type: Standard 520
• Number of teeth: 51
• Material: CNC 7075 aluminum inner ring, HCS outer ring
• Hex-Drive Interface: optimized transmission between rings, reducing stress on the rivets
• Finish: blue anodization and relief grooves for mud evacuation

The CAD design of the profile allows for weight reduction without sacrificing rigidity, while the double-ring configuration limits deformation under load. Riders will appreciate the precise alignment and longevity of the teeth during intensive competition use or on technical trails.

Notable compatibility: suitable for listed TM Racing models (MX 530 FI 2022, EN 530 FI ES 2022, MX 450 FI 2022). For secure mounting, adhere to the recommended torque specifications and the manufacturer's guidelines.
