At the heart of the 2009 MBK X-Power sport motorcycle, MBK utilizes a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 2.7 HP (2 kW) at 6,250 rpm while maximum torque reaches 2.9 Nm (2.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches).
On the scales, the X-Power measures 114.2 kg (252 lbs) dry. Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
