RFX Pro Series Armalite Double Compound Rear Sprocket (Steel/Aluminium) - 520 SprocketRef : RFX01028A / 1123236001

Manufacturer Ref: FXRS 50-48 ALBU

The RFX Pro Series Armalite 520 - 48 tooth sprocket is designed for demanding quad, motocross, and roadster riders seeking lightweight and robust performance. Its CNC-machined 7075 aluminum center reduces unsprung mass for a more responsive handling, while the high-carbon HCS steel outer ring maintains the integrity of the teeth against wear. The entire unit is anodized blue for a durable and aesthetic finish.

The "double ring" design with Hex-Drive interface enhances the transmission between the inner and outer rings and reduces stress on the rivets, offering a rigid architecture that limits twisting under load. Optimized relief grooves expel mud and dirt to slow wear in off-road conditions.
