    Excellent discussion on CVT for scooters. CVTs are also commonly used in snow machines and ATVs.

    I lightened the CVT variator weights on three scooters I have owned over the years: Honda Reflex (250cc), Honda Silverwing (600cc), and Yamaha Majesty (400cc).

    In each case, acceleration was noticably improved while not adversely affecting top speed or fuel economy.

    It's relatively easy job, costs little, and completely reversible (but you'll never want to).

    A related, but not the same, bit of tech is the multi-speed transmissions in RC cars.
    You can change the shift points with similar strategies. You can also adjust the bit point of the centrifugal clutch.
