Positioned in PGO's scooter motorcycle lineup, the 2011 PGO T-Rex 125 utilizes a 124.9 cc (7.6 cu in) oil & air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.5 HP (6.9 kW) at 8,000 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 76.1 HP per liter and a 1,250 rpm working window between peak torque (6,750 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the T-Rex 125 measures 110 kg (243 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.58 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.
