2023 Lexmoto Detroit 125 Technical Analysis & Specification Breakdown

Engineered by Lexmoto for the sport motorcycle segment, the 2023 Lexmoto Detroit 125 features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 9.4 HP (6.9 kW) at 8,500 rpm while maximum torque reaches 9 Nm (6.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 75.8 HP per liter and a 2,000 rpm working window between peak torque (6,500 rpm) and peak power (8,500 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 Detroit 125 measures 141 kg (311 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (15 kg per horsepower). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.35 L/100 km provides an estimated theoretical range of roughly 596 km (370 miles) between fill-ups, while factory top speed is listed at 105 km/h (65 mph).
