RFX Pro Series Armalite Rear Sprocket KTM SX/EXC SXF/EXCF 125-530 91-19
RFX Pro Series Armalite sprockets are designed and tested at the highest level by top World and British championship race teams.
New dual ring design gives the ultimate sprocket performance, reduced weight thanks to a 7075-T6 aluminium centre 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 maximises drive between the two parts and reduces the force on the rivets to zero unlike the competition.
Pro Series Armalite Sprocket Features:-
- CNC 7075 Aerospace aluminium Inner ring
- HCS Outer Ring
- Hex-Drive location between inner & outer ring
- CAD designed profile for lightness.
- New style mud clearing grooves to reduce wear.
- Rigid design increases torsional strength.
- Colour anodised for that factory bike look.
