Built around TGB's scooter motorcycle platform, the 2011 TGB Express 50 relies on a 49 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 4.9 HP (3.6 kW), transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 41.0 x 37.4 mm (1.6 x 1.5 inches) with a 9.2:1 compression ratio.
On the scales, the Express 50 measures 105 kg (231 lbs) dry. Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 6.8-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
