At the heart of the 2005 MBK X-.Power sport motorcycle, MBK pairs a 49.7 cc (3 cu in) liquid-cooled engine architecture with road-focused gearing. In factory specification, peak output is rated at 1.7 HP (1.3 kW) at 5,500 rpm while maximum torque reaches 2.6 Nm (1.9 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) with a 11.5:1 compression ratio.
On the scales, the X-.Power measures 113 kg (249 lbs) dry. Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 13.8-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
