2018 BMW K 1600 Grand America Technical Analysis & Specification Breakdown
Engineered by BMW for the touring motorcycle segment, the 2018 BMW K 1600 Grand America pairs a 1649 cc (100.6 cu in) liquid-cooled in-line six, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 160 HP (116.8 kW) at 7,750 rpm while maximum torque reaches 175 Nm (129.1 lb-ft) at 5,520 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 97 HP per liter and a 2,230 rpm working window between peak torque (5,520 rpm) and peak power (7,750 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 K 1600 Grand America measures 364 kg (802 lbs) wet (curb), translating to a power-to-weight ratio of 0.44 HP/kg (2.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,618 mm (63.7 in) wheelbase engineered for planted straight-line stability. The 26.5-liter (7 US gal) fuel tank paired with a rated consumption of 5.7 L/100 km provides an estimated theoretical range of roughly 465 km (289 miles) between fill-ups, while factory top speed is listed at 162 km/h (101 mph).
