Naraku Secondary / Final Drive Gears for 125cc – 170cc GY6 Scooters, ATVs, and Go Karts
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.
SPECIFICATIONS:
