Description
Like all GFB lightweight pulleys,these begin life as a single 6061-T6 aluminium alloy billet, and are then precision CNC machined to exacting tolerances. We then anodize them 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 doesnt 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, and Stronger urge.
