The Kawasaki 2000 National ATV Club Tour crossed the land
last year, visiting ATV clubs to:
1) Encourage responsible,
safe, ATVing activity and public image projection, and
2) Showcase Kawasaki's new baby: the Prairie 650, their
new V-twin-powered ATV.
Kawasaki bypassed
ATV magazine editors, taking the new machine directly to
ATV riders, before production and public release.
Since then, Kawasaki
held a "press introduction," also exhibiting
their new flagship quad at the Cochranton, PA, Poker Run
this
April, where photographer Steve Harkins captured the images
in this article.

Kawasaki tour coordinator Jerry Hinds and his lovely wife, Sherry,
presented the program for a combined ATV club meeting in my area
last November. The couple pilot a "dually" truck, towing
an enclosed trailer, decorated with images of straining, breaking
chains and outrageous "CAUTION!" signs, warning bystanders
of the wild and wooly cargo inside: in fact, a prototype Prairie
650 ATV.

During
his presentation, Jerry announced ten $2000 grants
Kawasaki offers ATV clubs for constructive charitable and ATV activity-enhancing
projects.

ENGINE. Not
a "warmed-over" motorcycle mill; 90-degree
V-twin; 633 cc; twin single overhead camshafts; 8 valves;
35 % more torque claimed than its nearest competitor.
Twin
32-mm Keihin DOWNDRAFT constant-velocity carbs; more on
that, later. Spin-on, accessible, oil filter.
FRAME.
Although the external dimensions approach those of the Prairie
400, the design is novel; even a quad of this displacement
meets a design weight maximum of 606 pounds.

Instead
of a fuel tank between the seat and the steering
head, we find: air intake/plenum
chamber (air box). The 4.8 gallon fuel tank sits below
and behind the seat, providing a lower center of
gravity.. Silencing
intake baffles behind the "fake" tank cover
plastic lead to a flat foam air filter (washable) encased
in plastic,
held by four metal clips. Beneath the filter, two vertical-axis
velocity stacks appear, eager to feed the twin Keihin
32mm CV downdraft carburetors. Breather hoses for the
carburetor
slide chambers protrude into the bottom of the air box.

Two
drain holes permit any fluid temporarily intruding into
the plenum chamber to drain (the engine obviously
appears capable of "swimability" up to the level
of the top of the velocity stacks on a continuous basis;
it could survive temporarily with water washed over the
top of the "tank," if allowed to drain shortly
thereafter).
Claimed ground clearance is, well,
considerable--since ground clearance is measured in so
many different ways; I won't go there-the suspension is
REALLY
cushy; actual ground clearance ought to be measured with
a typical rider weight aboard.
The beast has full floorboards, a wraparound
mud guard all around the plastic fenders, but no "mud
flaps;" A waterproof storage compartment area under
the seat offers access through an oval-shaped hole at the
seat/rack junction area; no towbar on the prototype (probably
and add-on accessory to lower production overall weight
figures).
The prototype Prairie 650 had steel racks front and rear
with "composite" (plastic) flat interior load-bearing
surfaces.

TRANSMISSION/DRIVETRAIN.
Some unique new wrinkles arise in the Prairie 650's entirely
new model, dual-range, belt-driven, continuously-variable
transmission (CVT). This robust system uses four friction
buttons in the drive clutch (instead of the three found
in the 400/300 cc Prairies), maintaining a more consistent
attitude between the two sheaves, providing smoother operation.
A wider operating range is claimed from the unit, despite
its more compact size and lighter weight than previous CVT's.
Does the new machine enjoy engine
compression braking? Not exactly, HOWEVER: A totally independent,
singularly separate, electrically-operated, speed-sensing
brake acts on the drive belt to slow the quad down when
the throttle is dropped to idle and the wheels are turning
(e.g., when descending hills or even just slowing down
after a straight-and-level run). This system is called the "Kawasaki
Engine Brake Control (KEBC)." A 2WD/4WD selector is
available; a rev limiter override switch permits digging
out in reverse, if necessary. Simple levers control the
drive modes and reverse.

Anyone
ever stuck, with one front wheel spinning helplessly
with a conventional front differential,
will appreciate the Prairie 650's rider-controlled locking
front end ("Front Differential Control," meaningful
when in 4WD). At any speed, in any range or gear, the
rider
may lock the front end by squeezing a left-hand lever on
the handlebars. This lever manually engages the clutch
pack
in the front end, connecting the two front axles, preventing
the runaway wheelspin of differential action when one
front
wheel loses traction.

SUSPENSION.
Independent McPherson struts up front, swingarm rear, with
adjustable damping and pre-loading; piggy-back reservoir;
7.0 in. front travel; 7.3 in. rear travel. When I asked
the Tour Coordinator Jerry Hinds why not a swing-axle rear,
stability, simplicity, lower weight [Editor's Note: See
Sidebar] and lower cost were offered as explanations,
with the assertion the lower center of gravity and overall
chassis design of the Prairie 650 worked well with the swingarm.
In the rubber department, 25X8-12 front and 25X10-12 rear
tires support this machine; production models will feature
aluminum wheels (the prototype used steel rims).

| BRAKES.
Besides
conventional hydraulic disks up front, the rear brake is
an internal, sealed, "wet," multi-disk system acting
on the rear final drive. Said to offer virtual maintenance-free
long-life operation, this system may be employed separately
from the front brakes by foot pedal; or by squeezing a lever
on the left handlebar (separate from the "Torque Transfer
Control" lever). Marrying the front and rear brakes through
the drivetrain in 4WD is practical, according to the Kawasaki
rep, because the rear brake acts linearly over its range.
INSTRUMENTATION.
"Military-style" LED
graphics display speedometer, odometer, twin trip meters,
clock and hour meter functions.

SUMMARY:
The Prairie 650 overcomes my objections to other models
by totally sealing the rear brake and providing off-throttle
braking from an automatic transmission; further, this new
machine answers some of my prayers in providing a rider-controlled
locking front end. I look forward to riding one, experiencing
all that torque and testing that suspension. Production
is scheduled to begin soon projected release to customers
is the first half of 2001;

|
Clearly,
Kawasaki at long last unleashed its engineers on the
ATV side of the house,
permitting them to design and build a quad from the ground
up, taking enthusiasts' "druthers" to heart.
Kawasaki may have a winner here.
Price will be comparable to other large-displacement utility
or sport/utility ATV's (around $ 7000 MSRP).
