Engineered by Lexmoto for the scooter motorcycle segment, the 2025 Lexmoto SRT 125 features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.6 HP (6.3 kW) at 7,500 rpm while maximum torque reaches 8.6 Nm (6.3 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 68.8 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 SRT 125 measures 115 kg (254 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (13.37 kg per horsepower). 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 1,305 mm (51.4 in) wheelbase engineered for quick, flickable steering geometry.
