Engineered by Lexmoto for the scooter motorcycle segment, the 2025 Lexmoto Diablo 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 Diablo 125 measures 114 kg (251 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (13.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,315 mm (51.8 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 106 km/h (66 mph).
