KAWASAKI KFX®400 SPORT ATV
The “leading edge” answer to purist demands
popular 400cc sport all-terrain vehicle (ATV) class
appeals to riders who want the leading edge of power,
performance and exhilaration. These competitive
riders are purists who will accept nothing less
than a manual transmission for maximizing engine
acceleration, demand powerful braking performance
and typically choose the
fastest line through a turn.
Kawasaki’s answer to this high-performance
demand is the KFX®400 sport ATV. The KFX400 is powered
by a 398cc, liquid-cooled, four-stroke engine featuring
double overhead cams and four valves atop a chrome
composite-plated aluminum alloy cylinder. Fed by
a new 37mm high-performance carburetor, it includes
electric start and has a counter balancer to reduce
The KFX400 engine utilizes a “dry
sump” design, with the engine oil being carried
in the tubes of the high-performance chassis instead
of the traditional location beneath the engine.
This design enabled engineers to shorten overall
engine height so it can be placed lower in the chassis
for enhanced stability while providing higher ground
Transmitting power from the engine
to the rear wheels is a high-performance five-speed-plus-reverse
manual transmission and efficient O-ring chain.
A high-performance powerband requires an equally
advanced chassis, so the KFX400 ATV engine rides
in a high-tensile steel frame and subframe. Suspension
duties are handled by dual front A-arms with new
fully adjustable shocks that provide 8.5 inches
of travel, while an aluminum-alloy swingarm with
fully adjustable shock provides 9.1 inches of travel
on the rear. Contributing to the KFX400’s low, 373-pound
dry weight are competition-inspired aluminum-alloy
wheels, and stopping power is provided by dual front
disc brakes and a single rear disc brake.
As with all off-highway vehicle
recreation, Kawasaki encourages ATV riders to ride
responsibly and to respect the environment. Kawasaki
will pay first-time buyers of a new Kawasaki ATV
$100 for completing an ATV rider safety course conducted
by the ATV Safety Institute (ASI). Interested consumers
can call ASI toll-free at 800-887-2887.
