Powerful 1700cc V-Twin engine from 2011 Kawasaki Vulcan-1700-Nomad
Long-stroke, liquid cooled, SOHC, 8-valve 1,700 cc V-Twin engine was designed to deliver high levels of torque. Bore and stroke measure 102 x 104 mm. Torque is approximately 15% greater than that of the VN1600D. Valve system uses a SOHC arrangement instead of OHV for more direct engine feel and easier merging onto freeways. Large capacity airboxes are located on either side of the engine. Semi-dry sump (like that on the VN2000) allowed the crankshaft to be lowered, enabling a longer stroke without increasing engine height. Both pistons are connected to a single crankpin. Primary balance is satisfied care of two counter-balance shafts. Small-diameter iridium spark plugs reach deep into the combustion chamber for high combustion efficiency, especially at low-load operation (near idling). Belt final drive is quiet and efficient and helps reduce maintenance chores. Using carbon fibre instead of Kevlar as a tensile material, the belt offers high strength (tensile strength is increased by 40%) with a slim size and light weight. Belt width (28 mm) is more comparable to that of the VN900 models (26 mm) than that of the VN2000 (40 mm).
Engine tuning variations
Two series of engines were designed for the new VN1700 models: one for the touring-oriented VN1700 Nomad (and VN1700 Voyager), and one for the cruising-oriented VN1700 Classic and VN1700 Classic LT. The difference was achieved through different FI settings and muffler systems. The result is that peak torque (up about 15% from the VN1600 Nomad) and peak horsepower (up about 20% from the VN1600 Nomad) occur at different rpm: cruising-oriented models are tuned such that peak performance occurs at lower rpm.
VN1700 Voyager / VN1700 Nomad VN1700 Classic/LT
Max torque @ 2,750 rpm @ 2,250 rpm
Max power @ 5,000 rpm @ 4,500 rpm
All models feature dual mufflers with the same base construction as those on the VN2000. However, the VN1700 Nomad (like the VN1700 Voyager) features twin mufflers (one on each side), where the VN1700 Classic and VN1700 Classic LT feature dual mufflers on the right side of the bike. The clutch on the VN1700 Nomad and VN1700 Voyager models features six damping springs for 3-stage progressive damping that contributes to smoother feeling when getting back on the gas.
Superior passing performance
Engine tuning offers superior acceleration in the 80-113 km/h (50-70 mph) range. Even in overdrive, the engine pulls strongly in this speed range, facilitating overtaking at highway speeds.
ETV System
Kawasaki’s first fully electronic throttle actuation system enables the ECU to control the volume of both the fuel (via fuel injectors) and the air (via throttle valves) 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 speed control. The simple system makes it easy to incorporate other systems, like cruise control (please see below). Twisting the throttle grip actuates a throttle pulley on the throttle body. The APS, also located on the throttle body, sends a signal to the ECU, which then actuates the throttle valves via a DC motor. Throttle position is confirmed to the ECU by Throttle Position Sensor (TPS). Redundancy in the system (APS and TPS each send two sets of signals to the ECU) ensures some control is maintained in case of failure. Because the throttle grip is connected to cables, the feel at the grip is like a standard cable-operated throttle. Transmission6-speed transmission with overdrive 6th gear is an overdrive gear, contributing to stress-free riding and better fuel economy when cruising at highway speeds. Cruise control (Vulcan 1700 Nomad only) Operation of the cruise control is conveniently from the right handle. Cruise control can be activated between 47 km/h (30 mph) and 137 km/h (85 mph) in 3rd gear or above. Operating the brake lever, clutch lever or rear brake pedal causes the cruise control to be disengaged. Closing the throttle beyond the “zero-throttle” position is another instinctive way to disengage the cruise control.
Chassis
With VN1700 series models featuring a more compact package than their predecessors, the new frame was designed for light weight and light handling.
Light handling
Designed from the start to be as light and slim as possible, the frame minimises the number of forged parts and trims any unnecessary meat. The only forged parts (the down-tube joint, engine brackets, side-stand bracket, rear fender/shock absorber bracket) are areas that require additional strength. The new frame is lighter than that of the VN1600A, with greater torsional rigidity. More compact in design, the VN1700 has a shorter wheelbase than both the VN2000 and VN1600. The compact design contributes to light handling. Shorter distance between the seat and frame head pipe facilitates handling at low speeds, especially when executing U-turns. Tire choice and suspension settings also contribute to the light handling.
Chassis variations
The VN1700 Nomad and VN1700 Classic LT add wind protection care of adjustable handlebar-mounted windscreens. Sub-windscreen and deflectors on the VN1700 Nomad further increase wind protection performance. The sub-windscreen covers the area between the windscreen and headlamp when the windscreen is in the raised position. The fork-mounted deflectors help direct air away from the rider’s legs. The VN1700 Nomad features hard, lockable panniers (same as those on the VN1700 Voyager). The top-opening panniers provide 38 litres of sealed storage space for overnight touring. On the VN1700 Classic LT, studded leather saddlebags (like those on the VN900D) offer convenient storage space. Rider and passenger seats differ between the touring-oriented VN1700 Nomad and cruising-oriented VN1700 Classic/Classic LT. The rider seat of the VN1700 Nomad is the same as that on the VN1700 Voyager; passenger seat is also sculpted for greater all-day comfort. Seats on the VN1700 Classic and VN1700 Classic LT are the same except for the studs. Also contributing to passenger comfort, the VN1700 Nomad features a luxury backrest with integrated passenger grab bars. On the VN1700 Classic LT, a studded tombstone-shaped backrest provides passenger back support. As a final contribution to passenger comfort, the VN1700 Nomad features passenger floorboards instead of the footpegs featured on the VN1700 Classic/Classic LT. Dual adjustable rear air-shocks ensure a comfortable ride feel. Settings are different between the VN1700 Nomad and VN1700 Classic/Classic LT. VN1700 Classic/Classic LT also feature chromed shock covers, contributing the luxurious finish of the rear of the bike. Front and rear guards on the VN1700 Nomad help protect the bike’s engine and panniers in the case of a stationary fall. Convenient helmet locks located on the left- and right-side pannier guards.
Styling
Kawasaki Cruisers have always been a showcase of craftsmanship and attention to detail. The VN1700 series models are no exception. Like on the VN2000 models and VN900 models before them, design of the engine covers and bodywork on the VN1700 models received meticulous care to ensure the bikes not only look good from any angle, but also that their elegant form is as pleasing to the touch as to the eye.
Engine
Basic engine structure has a great impact on a V-Twin engine’s appearance. Using a semi-dry sump enabled the engine’s long-stroke configuration without increasing its height. The line created by the top of the airbox and the cylinder heads forms a curved lined that continues to flow through the bike. Deeply chromed engine covers have curved upper surfaces. Their three-dimensional form adds volume and gives a quality appearance. The edges of the fins receive a special NC treatment that makes them gleam in sunlight. All the non-chromed parts of the engine have a matt black finish that further accentuates the chromed parts. Slim design of the belt drive contributes to appearance, especially on the VN1700 Classic.
Bodywork
The elegantly shaped fuel tank tapers at the rear, contributing to the VN1700’s curvaceous figure, its lines flowing through the rest of the bike. The fuel tank’s curves have constantly varying radii, giving the bike a dynamism that is both powerful and sexy. Its hand-sculpted contours are pleasing both to the eye and to the touch. Ignition switch allows on-position key removal, preventing key bunches from damaging the instrument cluster or tank while the bike is in operation. Turning the ignition switch collar to the “OFF” position turns the engine off and necessitates re-insertion of the key to restart. Multi-function LCD displays on the tank-mounted instrument cluster are controlled by switches on the right handle. Features include a gear position indicator (new for Kawasaki cruisers), fuel gauge, clock, odometer, dual trip meters, remaining range and average fuel consumption. Pushing the “S” switch to the left (“MODE-A”) toggles the lower display between “CLOCK”, “RANGE” (remaining cruising range) and “AVERAGE” (average fuel consumption). Pushing the “S” switch to the right (“MODE-B”) toggles the upper display from “ODO” to “TRIP-A” to “TRIP-B” and back. Kawasaki craftsmanship is also evident in the styling motif of the front fender. Liberal use of chrome contrasts nicely with the bodywork’s deep, lustrous paint. In addition to the engine, the fender brackets, light stays, pannier accents (VN1700 Nomad), front and rear guards (VN1700 Nomad), and rear shock covers (VN1700 Classic/Classic LT) are all chromed. Motif from the front fender continues on the rear fender. The VN1700 is the first Kawasaki Cruiser to feature an elegant LED taillight.
