At the heart of the 1983 Honda CB 125 TD-C naked motorcycle, Honda pairs a 124 cc (7.6 cu in) air-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 15 HP (10.9 kW) at 11,000 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 121 HP per liter and a 2,500 rpm working window between peak torque (8,500 rpm) and peak power (11,000 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 CB 125 TD-C measures 124 kg (273 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.27 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 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 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 113 km/h (70 mph).
