Technical Overview
2018 BMW F 800 GS Blackline LS Technical Analysis & Specification Breakdown
Positioned in BMW's enduro - offroad motorcycle lineup, the 2018 BMW F 800 GS Blackline LS pairs a 798 cc (48.7 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 85 HP (62 kW) at 7,500 rpm while maximum torque reaches 83 Nm (61.2 lb-ft) at 5,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 106.5 HP per liter and a 1,750 rpm working window between peak torque (5,750 rpm) and peak power (7,500 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 F 800 GS Blackline LS measures 217 kg (478 lbs) wet (curb), translating to a power-to-weight ratio of 0.39 HP/kg (2.55 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,575 mm (62 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 4.3 L/100 km provides an estimated theoretical range of roughly 372 km (231 miles) between fill-ups.
