Built around PGO's scooter motorcycle platform, the 2006 PGO T-Rex 125 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 95.2 HP (69.5 kW) at 7,500 rpm while maximum torque reaches 9.1 Nm (6.7 lb-ft) at 6,250 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 767.7 HP per liter and a 1,250 rpm working window between peak torque (6,250 rpm) and peak power (7,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the T-Rex 125 measures 110 kg (243 lbs) dry, translating to a power-to-weight ratio of 0.87 HP/kg (1.16 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,284 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 6.7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
