Engineered by Keeway for the enduro - offroad motorcycle segment, the 2021 Keeway TX 125 E4 utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 9,000 rpm while maximum torque reaches 9 Nm (6.6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 85.6 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 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 TX 125 E4 measures 142 kg (313 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (13.27 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
