HOW AFFORDABLE IS IT?
At $6499, the KingQuad 400
automatic is less expensive than the
$6699 Honda Rancher 420 Automatic,
the only other 400-class 4x4 ATV
with solid-axle rear suspension and
an automatic transmission. The foot-shift, five-speed KingQuad 400 is also
There are less expensive 4x4s with
independent rear suspension (IRS), like
Can-Am’s $6399 Outlander L 450 and
the $5899 Polaris Sportsman ETX 325.
The Sportsman 570 is $6499.
The 2015 KingQuad 400 has a new
camshaft, exhaust system, iridium
spark plug and engine control mapping
designed for stronger performance with
better fuel economy.
WHAT POWERS IT?
An air-cooled, fuel-injected, four-valve, single-cylinder, 376cc engine.
Air-cooled engines are far less common
than they once were, but they require
less care than liquid-cooled models.
There’s no coolant to check or change
and no water pump or radiator to
worry about. The Suzuki’s generous
cylinder fins and large fan-assisted oil
cooler keep it cool even in the most
challenging conditions. You don’t see
cold-start levers on many fuel-injected
quads, but the KingQuad 400 has one,
and, as with a choke on an air-cooled
quad, you need to have the lever on
for cold starts and then flip it to the off
position once the engine warms.
WHAT KIND OF TRANSMISSION DOES IT
A fully automatic, belt-type,
continuously variable transmission (CVT)
with high, low, neutral and reverse. A
centrifugal clutch before the primary
clutch protects the belt and provides
engine braking on downhills. The
Suzuki’s range selector is one of the
smoothest in the game.
WHAT KIND OF 4WD SYSTEM DOES IT
A simple one, but it works. On most
4x4s, you select 2WD or 4WD with a
thumb switch. The Suzuki has a simpler
mechanical lever on the handlebar, so
there are no electrical parts on the front
differential that can fail. There is also no
front differential-lock mode. Don’t sweat
the lack of a locking front differential.
The KingQuad can go practically
anywhere you want to go in 4WD.
IS IT FAST?
It moves for a 400cc 4x4. The
KingQuad 400 has always had a
healthy engine for its size, but the latest
version feels even stronger, especially
from the midrange to high rpm.
HOW IS THE POWER ON THE TRAIL?
Smooth at low speeds, with strong,
solid power as the revs build. The
Suzuki has one of the more fun,
responsive engines in the 400 4x4
class. It’s tractable on technical trails,
but it revs quickly, revs high and keeps
pulling at high revs. There’s plenty of
power for climbing challenging hills and
motoring through deep mud and sand.
WHAT KIND OF SUSPENSION DOES IT
Double A-arms up front and solid-axle, swingarm rear suspension with 6. 7
inches of travel at both ends. The front
and rear shocks are non-adjustable.
HOW DOES THE SUSPENSION WORK
It’s smooth but firm enough for
Air-cooling makes the KingQuad 400’s engine
riding trails quickly with good control.
A new cam and exhaust
system make the 2015
KingQuad 400 run
stronger than before,
and it gets better fuel
one of the simplest 4x4 engines to care for.
Fuel injection and the four-valve, overhead-
cam design give the Suzuki impressive power
and easy starting.
The KingQuad 400 has spacious ergonomics
and a comfortable shape.
