Secondary gear kit from Polini, teeth = 15/42.
A longer ratio allows for higher top end speed. Fitting a big bore kit does not always give the expected increased top end speed, it certainly improves acceleration well but not top end speed, Why? This often down the short gear ratios on your scooter, so if you find this is the case, the only way to combat this is by changing the gears to new longer ones.
