The MotoTec Alien is a 50cc 2-stroke dirt bike for young riders moving up from electric machines. It has an automatic centrifugal clutch, so there are no gears to change. The rider twists the throttle and the bike pulls away, and a pull start gets the engine running.
The chassis is steel. It has telescopic forks in front, a mono shock at the rear, and disc brakes at both ends. The outdoor rubber tires are 12.5x10, and the handlebars adjust for angle. The padded single-rider seat sits 22 inches high.
The 1 liter tank runs on a 25:1 unleaded fuel and oil mixture, for 10 or more miles of riding. Top speed is 25 mph. The bike is for off-road use only and is not street legal. It has no VIN, title or registration. Riders should always wear a DOT-approved helmet and protective gear.
