Built around Honda's allround motorcycle platform, the 2013 Honda TMX 155 features a 155.3 cc (9.5 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.5 HP (9.1 kW) at 8,000 rpm while maximum torque reaches 12.1 Nm (8.9 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 80.5 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 TMX 155 measures 108.3 kg (239 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.66 kg per horsepower). Rider ergonomics and chassis geometry center around a 743 mm (29.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,201 mm (47.3 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
