The DB17 125cc Manual Dirt Bike from TaoTao USA features larger tires and a taller seat height that makes it just right for adult riders. The extra size also means more ground clearance so the DB17 can handle rugged off-road riding. The front tire is 17" and the rear tire is 14". The 4-stroke, air-cooled engine is easy to maintain and easy to start. Dual disc brakes, and tough all-terrain tires combined with the powerful 125cc engine Tao Tao uses makes riding this a thrill!
