1998 Honda NX 125 TC Trans City Technical Analysis & Specification Breakdown

Positioned in Honda's super motard motorcycle lineup, the 1998 Honda NX 125 TC Trans City features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 13 HP (9.5 kW) at 8,500 rpm while maximum torque reaches 12 Nm (8.9 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 104.8 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 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 NX 125 TC Trans City measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
