Testimonials: "Got the variator, Amazing, all the performance issues gone, can't believe it has such an effect, I think the belt might actually slip a little at around 20kph when I accelerate hard. Thanks!" B.G., Wellington (Kitaco Type X on a Yamaha Jog) "The new variator pulley works very impressively. It keeps the motor in the power band all the time, and handles the hills much better. Its a bit better on top speed too" A.P., Nelson (Kitaco Type X on a Yamaha Jog)
