Product details
The RFX Elite sprocket takes a race-proven design and brings it up to date. The proven features of the original are all still there, including the solid inner ring and the grooves that clear mud, but the new design adds strengthening gussets that reinforce the sprocket while keeping it light.
Chamfered edges on the weight-reducing cutouts give a sleek, modern look, help shed mud and take out extra weight without affecting the strength or structure of the sprocket. The teeth have also been subtly revised so the chain releases cleanly, which cuts wear and helps both your chain and sprocket last longer.
Each one starts as aerospace grade 7075-T6 aluminium alloy, which is CNC machined and then given a 2-tone anodised and polished finish. RFX makes the design in 6 colours for a factory bike look.
Key features
- 7075 aerospace aluminium, CNC machined
- Gussets for added strength
- Mud clearing grooves that extend sprocket life
- Weight-reducing cutouts with chamfered edges
- Anodised colour with a polished 2-tone finish
- Laser etched RFX logo
