One of the things that has made modern ATV's easier to ride is an automatic transmission called a CVT (Constant Variable Transmission). First used in snowmobiles as far back as the 1950's, CVTs are now the most popular transmission choice for ATV manufacturers. Even the automobile industry has seen the advantages of the CVT and many current models have them.
In a CVT you have one large belt, primarily composed of rubber which connects the engine (the primary) to the wheels (the secondary). It is a much simpler set up than a geared transmission and rather than just 5 or 6 forward gears, there are an infinite number of gears as the belt rides up and down the sheaves.
This is a great video for understanding how a CVT works
There are many positive attributes to a CVT but one big negative is that a CVT belt will wear and eventually break as compared to a geared transmission. Any ATV with a CVT is prone to a belt failure over time, but even more so if the ATV has been modified with bigger tires. A CVT belt failure will result in a complete disconnect from the engine to the wheels and leave the ATV unable to move.
