Engineered by Aprilia for the enduro - offroad motorcycle segment, the 2005 Aprilia MX 50 relies on a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches) with a 12.0:1 compression ratio.
On the scales, the MX 50 measures 95 kg (209 lbs) dry. Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
