GFB Lightened Underdrive Pulley Kit 

Made from single 6061-T6 aluminium alloy billet, then precision CNC machined to exacting tolerances and anodized black for a stealthy appearance and superior wear resistance.

This kit is supplied with 3 pulleys, not just for looks - the combined saving of 2.2 kg is significantly more than what is achieved by replacing just the crank pulley alone.

The weight doesn’t tell the whole story either - even though the saving is a significant 77%, the actual rotating inertia reduction (inertia is what counts) is 83%.

Like all GFB lightweight pulley kits, you can feel the improvements:

  • Sharper throttle response
  • Engine feels more willing to rev
  • Stronger “urge”
