Alrigt, first off i'm not some stupid kid, i just didnt want to fill out the form...Second, that guy is a moron. The motors that are used on this go-quad are made by "Zenoah Komatatsu." This company makes engines for EVERYTHING, including Construction machines like bulldozers. The motors are incredible, i'm a hardcore gopeder and i know quite a bit about em.THese go-quads are awsome, mainly designed for racing, but are a lot of fun and very easy to use. THe drive system is a spindle, which requires much less maintence, unlike belt drives which snap belts like crazy.
