Positioned in Honda's scooter motorcycle lineup, the 1978 Honda CB 750 F 2 features a 736 cc (44.9 cu in) air-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 73 HP (53.3 kW) at 9,000 rpm while maximum torque reaches 62.4 Nm (46 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 99.2 HP per liter and a 1,500 rpm working window between peak torque (7,500 rpm) and peak power (9,000 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 750 F 2 measures 253 kg (558 lbs) wet (curb), translating to a power-to-weight ratio of 0.29 HP/kg (3.47 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.19 L/100 km provides an estimated theoretical range of roughly 347 km (216 miles) between fill-ups, while factory top speed is listed at 197 km/h (122 mph).
