Built around PGO's scooter motorcycle platform, the 2008 PGO G-MAX 50 pairs a 49 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.1 HP (2.2 kW) at 6,250 rpm while maximum torque reaches 3.5 Nm (2.6 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 6.8:1 compression ratio.
On the scales, the G-MAX 50 measures 105 kg (231 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,365 mm (53.7 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
