RFX Motorcycle crown Suzuki Pro Series 520 DR 250 S

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

The dual sprocket design offers optimal performance, reduced weight thanks to a 7075-T6 aluminium centre, and a longer lifespan of the teeth due to the special high-carbon steel outer section.

The Armalite sprockets also feature a hexagonal interface between the inner and outer rings, a revolutionary technology that maximises the transmission between the two parts and eliminates any force exerted on the rivets.

Features:

• CNC 7075 aluminium inner ring
• HCS outer ring
• Hex-Drive location between the inner and outer rings
• CAD-designed profile for increased lightweight.
• New mud release groove style to reduce wear.
• The rigid design increases resistance to twisting.
• Anodised colour
