The purpose of underdrive gears is to multiply the torque delivered by the engine and transmission. Gears can be thought of as complex levers. In other words, they provide a mechanical advantage that multiplies work—in this case, torque—to help the engine’s power move the vehicle. Lower gears are like a longer lever: They provide more mechanical advantage. Higher gears are like a shorter lever: They provide less mechanical advantage. It’s similar to when you use a long breaker bar instead of a short ratchet handle to remove tight lug nuts. Just like a long bar puts more torque on a lug nut, lower drive gears provide more torque to the wheels.

The heavy bikes benefit most from this part, especially those running the VM-1 cam profiles as they give up a little bottom end TQ for the upper end HP increase. RPMs will increase with this pulley (EX: 3000 is now approx 3210 in 6th gear)
