Chinese junk you'd be better off buying a used yamaha / suzuki / honda etc . You'll be lucky if it lasts one trail ride. If you are a city boy driving it around your yard that's all they are good for IMO.
Buy a used yamaha, suzuki,honda, or something along them lines if you want to save money. I got a chines quad thrown in with a used polaris i bought it was brand new and let the kids ride it around my acerage one weekend and there was nothing left of it. Im just glad it was free but it did run longer then the polaris i bought from the same guy. Wouldnt buy either again.
