That Big Bear 400 of yours is never going to win any drag races, but that's no problem, Yamaha designed the Big Bear as a hardworking utility ATV, not as a sports machine. While it may not get from A to B the fastest, it will get from A to B through even the toughest terrain and adverse conditions. The Big Bear's low gearing and powerful 386cc SOHC engine will drive it through almost anything, from snow and ice, to deep mud and bogs. That is the sort of performance you don't want your Big Bear to lose, which means you'd better service and maintain your ATV on a regular basis. Of course service and maintenance means replacing worn parts with new ones, and the best thing you can do at every service is to fit genuine Yamaha Big Bear 400 parts and not aftermarket ones.
