RFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 SprocketRef : RFX01172A / 1123236019

RFX Pro Series Armalite Composite Sprocket - 520 (48 Teeth)

Designed for demanding riders, this RFX Armalite sprocket combines a machined 7075-T6 aluminum core with a high carbon density steel (HCS) outer ring. The double-ring mounting lightens the part while concentrating strength on the chain contact area, ensuring crisp power delivery and better wear management on muddy or abrasive terrains.

• Color: anodized black, resistant to splashes and abrasion.
• Materials: CNC 7075 aluminum inner ring, HCS outer ring.
• Configuration: 48 teeth, 520 pitch — compatible with standard 520 transmissions.
• Hex-Drive interface between inner and outer ring for optimal force transmission without stressing the rivets.
• Optimized CAD profile and mud grooves to reduce debris accumulation and localized wear.
• Stiff design increasing torsional resistance during acceleration and heavy loads.

Versatile, it fits quad, motocross, and roadster applications. Ideal for mounting on machines like TRIUMPH TF 450-X, DUCATI DESMO 450 MX, or STARK FUTURE VARG EX. Supplied with installation instructions: adhere to the manufacturer's torque specifications and use Loctite if recommended to ensure the safety and longevity of your transmission.
