TrailMaster's TM31X is a feature-packed full-size dirt bike that's built for motocross and ready to set record times! The TM31X has motocross ergonomics with a 19 inch front wheel and 16 inch rear wheel, and a race suspension system gives it 13 inches of ground clearance and makes navigating any type of terrain nearly effortless! With a powerful 223cc engine pushing 16 horsepower at its full output, this bike can reach speeds of more than 55 miles per hour depending on loaded weight. A smooth-shifting manual 5-speed transmission gives riders excellent control over their ride and gives the TM31X durability that will stand up to years of low-maintenance riding. Electronic digital CDI ignition allows for simple startups with a key, and a kick backup starter makes sure you're never stuck even in bad weather conditions or with battery troubles. The premium X model of this bike features an LED headlight, full digital dashboard, rear view mirrors, turn signals, a horn, and a license plate mount. Comes in a selection of solid colors with cool racing graphics!
