Positioned in Lauge Jensen's custom - cruiser motorcycle lineup, the 2011 Lauge Jensen 1800 utilizes a 1792 cc (109.4 cu in) v2, four-stroke layout. In factory specification, peak output is rated at 69.7 HP (50.9 kW) at 4,300 rpm while maximum torque reaches 120 Nm (88.5 lb-ft) at 3,100 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 38.9 HP per liter and a 1,200 rpm working window between peak torque (3,100 rpm) and peak power (4,300 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the 1800 measures 323 kg (712 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.63 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,780 mm (70.1 in) wheelbase engineered for planted straight-line stability. The 19.5-liter (5.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
