The day after I bought it we took it out for a day of nothing but trails. After 6 hours of on and off riding, the lil guy held up strong with no problems and actually out ran some of the other quads. A few of the other quads had mechanical problem while I was spinning donuts around em (not literally). It still starts on the 1st or 2nd kick and honestly just runs flawlessly. I hate to brag but i really did get a good deal with this guy.
