RFX Motorcycle crown Aprilia RXV 450 [450]/Aprilia SXV 450 [450]/Aprilia RXV [550]

The RFX Pro Series Armalite sprockets are designed and tested to the highest level by the racing teams of world and British championships.

The dual-sprocket design offers optimal performance, reduced weight due to a 7075-T6 aluminium core, and a longer tooth lifespan thanks to the outer layer made from special high-carbon steel.

The Armalite sprockets also feature a hexagonal interface between the inner ring and the outer ring, a revolutionary technology for sprockets that maximises the transmission between the two parts and reduces the force on the rivets to zero.

Features:

• 7075 CNC aluminium inner ring
• HCS outer ring
• Hex-Drive placement between the inner and outer rings
• CAD-designed profile for lighter weight.
• New mud clearance groove style to reduce wear.
• Stiff design increases torsional strength.
• Anodised colour
