RFX Pro Series Armalite sprockets are designed and tested at the highest level by top World and British championship race teams.
The dual ring design gives the ultimate sprocket performance, reduced weight thanks to a 7075-T6 aluminum center and long lasting teeth life thanks to the high carbon steel outer.
Armalite sprockets also feature a hexagon drive interface between the inner and outer ring, this is revolutionary technology for sprockets and maximizes drive between the two parts and reduces the force on the rivets to zero unlike the competition.
Product Features:
CNC 7075 Aerospace aluminum Inner ring
HCS Outer Ring
Hex-Drive location between inner and outer ring
CAD designed profile for lightness
New style mud clearing grooves to reduce wear
Rigid design increases torsional strength
Color anodized for that factory bike look
