Rear sprocket RFX Pro Series CR 125 R (JE01) - Steel/Aluminium - 520

Rear sprocket RFX Pro Series CR 125 R (JE01) - Steel/Aluminium - 520

The RFX Pro Series Armalite sprockets are designed and tested at the highest level by the best racing teams in the World and British Championships.

The two-ring design ensures maximum gear performance, reduced weight thanks to the 7075-T6 aluminum center, and long tooth life thanks to the high-carbon steel outer part.

Armalite gears also feature a hex drive between the inner and outer rings, which is a revolutionary technology for gears and maximizes the drive between the two parts and reduces the force on the rivets to zero unlike the competition.

Features:

• CNC 7075 Aerospace Aluminum Inner Ring
• HCS outer ring
• Hexagonal drive between inner and outer ring
• CAD designed profile for ease of use.
• New style mud clearance channels to reduce wear.
• The rigid construction increases torsional strength.
• Colored anodizing for a factory look on the bike.
