At the heart of the 1978 Suzuki GS 1000 classic motorcycle, Suzuki features a 997 cc (60.8 cu in) air-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 90 HP (65.7 kW) at 8,200 rpm while maximum torque reaches 83.4 Nm (61.5 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 90.3 HP per liter and a 1,700 rpm working window between peak torque (6,500 rpm) and peak power (8,200 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the GS 1000 measures 255 kg (562 lbs) wet (curb), translating to a power-to-weight ratio of 0.35 HP/kg (2.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,505 mm (59.3 in) wheelbase engineered for balanced agility and highway composure. The 20-liter (5.3 US gal) fuel tank paired with a rated consumption of 7.2 L/100 km provides an estimated theoretical range of roughly 278 km (173 miles) between fill-ups, while factory top speed is listed at 219 km/h (136 mph).
