RFX Motorcycle crown Aprilia RXV 450 520

The RFX Pro Series Hi-Carbon Steel (HCS) sprockets are perfect for riders looking for longevity and good value for money, while offering a unique quality that you won't find anywhere else.

The certified high-carbon steel provides unbeatable wear properties, and its high strength compared to mild steel allows for a lighter profile, which means the weight increase compared to aluminium is kept to a minimum.

The RFX HCS sprockets are laser cut for greater precision and tighter tolerance thresholds.
