2009 KAWASAKI Vulcan 1700 Voyager,

Powerful 1700cc V-Twin engine

• Liquid cooled, 4-valve per cylinder, fuel-injected 1700cc V-twin engine
• Long-stroke 102 x 104mm bore and stroke helps deliver high levels of torque approximately 15 percent greater than that of the Vulcan 1600
• Valve system is based on the Vulcan 2000, but uses a SOHC arrangement instead of OHV for more direct engine feel and quicker revving
• Semi-dry sump allows a lower crankshaft placement and a longer piston stroke without increasing engine height
• Single-pin crank provides the desirable power-pulse feel
• Twin counter-balancers handle smoothing the engine pulses
• A large capacity airbox is located on both sides of the engine
• Small-diameter iridium sparkplugs reach deep into the combustion chamber for high combustion efficiency, especially at low-load operation (near idling)
• Features dual mufflers, one on each side of the bike
• Engine tuning offers superior acceleration in the 50-70mph (80-113km/h) range
• Even in overdrive, the engine pulls strongly in this speed range, facilitating overtaking at highway speeds

Next Generation FI

• Based on systems already on Ninja 650R and Vulcan 900
• Utilizes one sensor in place of the usual three, for less complexity and weight
• The touring-oriented Voyager utilizes a FI and exhaust set up to deliver its torque and horsepower peak at a higher rpm

Electronic Throttle Valve System

• Kawasaki’s first fully electronic throttle actuation system enables the ECU to control the volume of intake air (via throttle valves) and fuel (via fuel injectors) delivered to the engine. Ideal fuel injection and throttle valve position results in smooth, natural engine response
• Control of both fuel injection and airflow enables precise cold-engine idling spee
