Even with UNI and performance CDI and coil, it barely ran faster than 30 mph. Because of the gearing, the CVT belt did not have to be replaced for over six years due to aging and it still had over 2/3 of the original clutch pads. This little 150cc had no problems running in loose sand or hitting small dunes at 20-25 mph because of its setup.

You make a very good point, Pete! The higher ratios (torque) take a lot of strain off the belt, clutch and chain.There's some that can't keep belts or clutches from overheating and failing. It may be that they are simply not geared correctly for their riding style.
