Technical Overview
2009 MBK MachG Air Cooled Technical Analysis & Specification Breakdown
Engineered by MBK for the scooter motorcycle segment, the 2009 MBK MachG Air Cooled features a 49 cc (3 cu in) air-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 2.7 HP (2 kW) at 7,000 rpm while maximum torque reaches 2.8 Nm (2.1 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 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 11.6:1 compression ratio.
On the scales, the MachG Air Cooled measures 82 kg (181 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,210 mm (47.6 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
