King Of Cruisers - Kawasaki Vulcan 2000
by Staff Writer

With the largest V-twin
engine in a mass-production motorcycle, amazing torque, unique style and superb
craftsmanship, the Vulcan 2000 truly is the king of cruisers.
Big becomes a well-used word, as you learn the impressive technical specifications of the
bike. Power for this stylish cruiser comes from a massive V-twin engine featuring a bore
and stroke of 103 x 123.2mm, forged pistons, alloy-steel connecting rods, huge 220mm
flywheels, dual cams located within the one-piece crankcase and right-side pushrods
actuating four valves per cylinder. Valves are suitably super-sized, with a pair of 40mm
intakes and 36mm exhausts.
To provide sharp throttle
response at any rpm, the Vulcan 2000s electronic engine control unit (ECU) manages
electronic fuel injection with its dual 46mm throttle bodies and sub throttle valves, as
well as the iridium spark plug ignition system. The sub throttle valves provide the Vulcan
2000 with a smooth, linear power band, while the highly sophisticated fuel injection
systems fine atomizing injectors deliver an ultra-fine mist of fuel/air mixture to
the cylinders for greater combustion efficiency, increased power and optimum fuel economy.
This brings almost faultless response from the big twin. I say almost, as it
is possible to catch the injection out if you are a little quick off and then on the
throttle at higher rpms.
So what does all this add
up to? Well, in a country where good is bad, and bad is even better, the Vulcan 2000s
power output can only be described as bad. Making 116 horses at 5,000 rpm, and
a mind blowing 196 Newton Meters of torque (145 ft/lb) at just 3,000 rpm, the Vulcan is
not only the largest production V-twin cruiser; it is the most powerful.
Visually, the motor is
just as stunning, taking up a large amount of real estate in between the massive steel
frame rails. And, the first thing that strikes the eye, after the huge attractive air
cleaner cover, is the chrome pushrod tubes that actually contain pushrods. Notably, Kawasaki
engineers chose to utilize a push rod design in order to reduce engine height, which
directly contributes to the Vulcan 2000s low center of gravity and relatively low
seat height. Plus, hydraulic valve lash adjusters automatically maintain zero valve
clearance for smoother, quieter operation.
Looking at the engine
again, you could be forgiven for taking the new Vulcan engine for an air-cooled unit, with
the polished cylinder fins standing out against the matte black cylinders. In reality,
only the top quarter of the V-twin engine is liquid cooled, while temperatures for the
bottom three-quarters of the engine are managed by stylish and highly functional cooling
fins. A closer look reveals the radiator tucked between the front-down tubes. Finished in
black, it blends with the frame so as not to give away the Vulcans secret. Dual
exhaust pipes and mufflers emit a distinctive V-twin rumble, and include honeycomb
catalyzers to reduce emissions.
The gearbox contains five
speeds and has a nice easy operation to it. A resounding thunk greets the
rider when first gear is selected, and a good hearty boot can be employed on the heel
shifter for selecting neutral again at stoplights. You will really like this feature, and
the fact that you will not feel as if your feet are too far out in front of you once under
way. Toe only shifting is effortless, with no false neutrals. Shifting with your heel is a
very straightforward affair, needing only the lightest of nudges to engage the next ratio.
A Hyvo primary drive
chain transfers torque from the big V-twin engine to the five-speed transmission case,
which houses a multi-plate wet clutch. To fully benefit from the Vulcan 2000s
advanced electronics, a gear position sensor in the transmission sends signals to the ECU,
further enhancing fuel injection volume and ignition timing, and thus improving
performance. Final drive to the rear wheel is provided by smooth, quiet and low
maintenance belt drive.
The Vulcan 2000
motorcycle rides on bright, cast aluminum 16-inch wheels with a 150/80 front radial tire
and a huge, 200/60 rear radial tire. Dual 300mm front disc brakes with four-piston
calipers and a single rear disc brake with two-piston caliper bring this big cruiser to
smooth, powerful stops
The Vulcan 2000s
rear tire is the largest ever used on a production V-twin cruiser. It does not look
abnormally large, because the rest of the bike is so big, but you may wonder if it will
make for awkward handling. But once in the saddle, you will completely forget about it, as
it has no negative effects on the bikes handling what so ever.
Styling that puts the
Vulcan 2000 at the forefront of cruiser design includes a powerful four-bulb,
projector-type headlight encased in a signature chrome Nacelle headlight the first
for a production cruiser. Adding to its high-end status is the chrome instrument panel
with its large-face speedometer; mounted on a stretched, 5.5-gallon fuel tank, the
V-shaped panel keeps the rider informed with an LCD display and warning lamps. The
bucket-type saddle with locking passenger seat complements the Vulcan 2000s long,
curving silhouette while providing all-day riding comfort.
The Vulcan 2000 provides
you with more torque than you could possibly need. In other words, it is just enough.
