The MotoTec X4 combines serious power and durability in a mid-size dirt bike built for teens and adults. With a 150cc 4-stroke engine, a 5-speed manual transmission with clutch, and a rugged chromoly steel frame, it delivers true motocross performance. Electric start, an upgraded Nibbi carburetor, and off-road styling give the X4 big-bike attitude in a manageable package.
