Built around Lexmoto's naked motorcycle platform, the 2023 Lexmoto LS-Z 125 features a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.7 HP (9.3 kW) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 102.4 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the LS-Z 125 measures 149 kg (328 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.73 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 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 111 km/h (69 mph).
