The MotoTec Supermoto (DB02) is a 50cc two-stroke mini dirt bike with low-profile 6.5-inch supermoto tires instead of tall off-road wheels. The tires are 90/65-6.5 at the front and 110/50-6.5 at the rear, which puts more contact patch on hard ground. It is built for closed courses, go-kart tracks and packed dirt, not rough trail.
The layout is simple. The rigid frame has no front or rear suspension, and the bike weighs 37 lbs dry. A pull cord starts the engine, and an automatic centrifugal clutch means there is nothing to shift. A single rear disc brake handles stopping. The seat height is 21 inches.
The 50cc air-cooled two-stroke engine is EPA approved and runs on a 25:1 premix of unleaded gasoline and two-stroke oil. The 1-liter tank gives 10-plus miles of riding, and top speed is 25 mph. Use it on smooth, even surfaces with an adult watching, not for jumps, ruts or rocky trail. Adult assembly and supervision are required. It is for off-road recreational use only and is not street legal. It has no VIN, title or registration. Riders should wear a DOT-approved helmet and protective gear, and follow local off-road vehicle laws.
