Engineered by Honda for the sport touring motorcycle segment, the 1985 Honda GB 250 Clubman relies on a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 30 HP (21.9 kW) at 9,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120.5 HP per liter, 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 GB 250 Clubman measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.23 HP/kg (4.33 kg per horsepower). The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 3.61 L/100 km provides an estimated theoretical range of roughly 471 km (293 miles) between fill-ups, while factory top speed is listed at 153 km/h (95 mph).
