Positioned in Kymco's atv motorcycle lineup, the 2010 Kymco MXU 400 utilizes a 366.9 cc (22.4 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 81.0 x 72.1 mm (3.2 x 2.8 inches) with a 10.5:1 compression ratio.
On the scales, the MXU 400 measures 306 kg (675 lbs) dry. Rider ergonomics and chassis geometry center around a 848 mm (33.4 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,293 mm (50.9 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
