Technical Overview
2024 BMW R18 Roctane Technical Analysis & Specification Breakdown
Engineered by BMW for the custom - cruiser motorcycle segment, the 2024 BMW R18 Roctane relies on a 1802 cc (110 cu in) oil & air-cooled two cylinder boxer, four-stroke powerplant. In factory specification, peak output is rated at 91 HP (66.4 kW) at 4,750 rpm while maximum torque reaches 158 Nm (116.5 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 50.5 HP per liter and a 1,750 rpm working window between peak torque (3,000 rpm) and peak power (4,750 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the R18 Roctane measures 374.2 kg (825 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.11 kg per horsepower). Rider ergonomics and chassis geometry center around a 719 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,720 mm (67.7 in) wheelbase engineered for planted straight-line stability. The 16.01-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 180 km/h (112 mph).
