Built around Honda's scooter motorcycle platform, the 2003 Honda FES 125 Pantheon relies on a 124.8 cc (7.6 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 15 HP (10.9 kW) at 7,000 rpm while maximum torque reaches 15 Nm (11.1 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 120.2 HP per liter and a 500 rpm working window between peak torque (6,500 rpm) and peak power (7,000 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 FES 125 Pantheon measures 145 kg (320 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 745 mm (29.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
