MotoTec X4 150cc 4-Stroke Dirt Bike
Ready for Rugged Trails — MotoTec X4
The MotoTec X4 is a 150cc 4-stroke dirt bike built for off-road reliability and straightforward use. It combines electric and kick start, a 5-speed manual transmission with clutch, durable suspension and brakes, and a reinforced frame so you can spend more time riding and less time fixing or fussing with setup.
