SUPER CLEAN
The KFX®400 is for serious sport riders who demand high-performance for the track, trails and dunes. And the KFX400 delivers, thanks to its high-tech, four-stroke engine, manual transmission, lightweight racing-type chassis and disc brakes.
This four-wheeled Kawasaki is propelled by a highly responsive 398cc, liquid-cooled, four-stroke engine with double overhead cams and four valves atop a chrome composite-plated aluminum alloy cylinder. Fed by a 37mm high-performance carburetor, it includes electric start and has a counterbalancer to reduce vibration.
The KFX400 engine utilizes a “dry sump” design, shortening overall engine height so it can be placed lower in the chassis for enhanced stability while providing higher ground clearance.
Transmitting power from the engine to the rear wheels is a high-performance five-speed-plus-reverse manual transmission and efficient O-ring chain.
Such power requires a chassis to match, so the KFX400 ATV engine rides in a high-tensile steel frame and subframe. Suspension duties are handled by dual front A-arms with 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.
