Positioned in Lexmoto's sport motorcycle lineup, the 2023 Lexmoto RSS 125 EFI pairs a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.1 HP (10.3 kW) at 9,000 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 112.8 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the RSS 125 EFI measures 163 kg (359 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.56 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 14.5-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 113 km/h (70 mph).
