RFX Pro Series Elite Aluminum Sprocket - 520: a rear sprocket designed for off-road use. Machined from 7075 aluminum using CNC technology, it combines lightweight construction with road stability for motocross riders. Its CAD-optimized profile minimizes material to reduce weight without sacrificing rigidity, while the laser-etched RFX logo attests to the attention to detail in the finish.
