Engineered by Kawasaki for the sport touring motorcycle segment, the 2012 Kawasaki Vulcan VN1700 Voyager Custom relies on a 1700 cc (103.7 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 71.1 HP (51.9 kW) at 5,000 rpm while maximum torque reaches 136 Nm (100.3 lb-ft) at 2,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 41.8 HP per liter and a 2,250 rpm working window between peak torque (2,750 rpm) and peak power (5,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Vulcan VN1700 Voyager Custom measures 382 kg (842 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.37 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,666 mm (65.6 in) wheelbase engineered for planted straight-line stability. The 20.06-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
