    Belt Size

    I have noticed in a few of the post something about longer belts . Why do you need them & what does it do for performance?

    longer belts increase the travel on the pulleys and this will give you more ratio combinations, but belt width is just as crucial . 90cc atv's normally have longer belts because they have more power to utilize the greater ratio.

    My boys 50 has this belt. It's a Bando VS with the numbers 780-165-30. Can this be upgraded?

    I have 2 girls that like to talk on the phone but conveniently don't hear the beep in.

    With a performance variator or a modified stock variator the 788 belt should provide a nice gain for the 70cc quads...

    It does for us....

    The 788 belt is wider....as well....

    Isnt the 788 a 17 instead of a 16.5 ? If so it will help out with top end nicely.
