Built around Skyteam's allround motorcycle platform, the 2009 Skyteam T-Rex 125 features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, maximum torque reaches 7.3 Nm (5.4 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 52.4 x 57.0 mm (2.1 x 2.2 inches) with a 9.0:1 compression ratio.
On the scales, the T-Rex 125 measures 93 kg (205 lbs) dry. Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,225 mm (48.2 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
