2007 MBK Booster X Technical Analysis & Specification Breakdown
Positioned in MBK's scooter motorcycle lineup, the 2007 MBK Booster X relies on a 49 cc (3 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3.7 HP (2.7 kW) at 7,500 rpm while maximum torque reaches 3.7 Nm (2.7 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 38.0 x 43.5 mm (1.5 x 1.7 inches) with a 12.0:1 compression ratio.
On the scales, the Booster X measures 87 kg (192 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 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
