Positioned in Kymco's atv motorcycle lineup, the 2009 Kymco MXU 50 relies on a 49 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 4.5 HP (3.3 kW) at 6,000 rpm, transferring power to the rear wheel through belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.0 mm (1.5 x 1.6 inches) with a 10.0:1 compression ratio.
On the scales, the MXU 50 measures 100 kg (220 lbs) dry. Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,105 mm (43.5 in) wheelbase engineered for quick, flickable steering geometry. The 8.1-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
