Engineered by Tomos for the minibike, sport motorcycle segment, the 2010 Tomos MC50 Junior utilizes a 49 cc (3 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 2.4 HP (1.7 kW), transferring power to the rear wheel through a automatic gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 38.0 x 43.0 mm (1.5 x 1.7 inches) with a 10.0:1 compression ratio.
On the scales, the MC50 Junior measures 89.4 kg (197 lbs) dry. Rider ergonomics and chassis geometry center around a 625 mm (24.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 2.5-liter (0.7 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
