2018 KingQuad 400ASi

In 1983, Suzuki introduced the world’s first 4-wheel ATV. Today, Suzuki ATVs are everywhere. From the most remote areas to the most everyday tasks, you’ll find the KingQuad powering a rider onward. Across the board, our KingQuad lineup is an exceptional group of ATVs.

Whether you’re working hard or getting away from it all, the 2018 Suzuki KingQuad 400ASi helps you every step of the way. The fully automatic Quadmatic transmission has two and four-wheel drive modes to handle rough trail conditions while completing even the most demanding chores. Along with exceptional engine performance across the powerband, its high-performance iridium spark plug and Pulsed-secondary AIR-injection (PAIR) system helps provide outstanding fuel efficiency, and clean emissions.

Powerful fuel-injected, four-stroke engine is easy on gas
Large fuel tank & plush seat delivers extended, comfortable riding range
Fender-mounted shifter controls the QuadmaticTM transmission
Select 2WD or 4WD via a handlebar-mounted lever
Rugged body work and full racks to tackle any task
The KingQuad 400ASi’s fuel-injected 376cc four-stroke, four-valve engine produces efficient power and driveablity
Suzuki’s class-leading fuel injection smooth’s power output, especially in the mid-to-high range, and provides excellent cold starting. The system uses 3-D maps for optimum ignition, creating responsive yet environmentally compliant performance
Suzuki Advanced Cooling System (SACS) uses an oil cooler and thermostat-controlled cooling fan to shed engine heat during hard work or cargo hauling
Push-button electric starting has a start-in-gear function allowing starting without shifting to neutral (as conditions permit)
The Engine Control Unit (ECU) has slip control logic, which adjusts fuel injector duration and timing to improve drivability and grip in loose/slippery conditions
Highly efficient iridium spark plug contributes to better combustion, cleaner emissions and longer plug life. Engine starting under low temperature is also improved
Pulsed-secondary AIR-injection (PAIR) system and catalyst-equipped exhaust system help the ATV meet emission standards while maintaining a high level of performance
The QuadmaticTM transmission is a fully automatic, CVT (Continuously Variable Transmission) with selectable high-low sub-transmission and reverse for maximum traction and fuel efficiency
Automotive gate-type gearshift lever lets you conveniently choose high- or low-range, neutral or reversereverse
Select two- or four-wheel drive with the flip of a handlebar-mounted lever. The shaft drive system is reliable and durable, and is nearly maintenance-free
Torque-sensing limited-slip front differential provides maximum traction and light steering when in 4WD mode
An advanced engine-braking system minimizes free-wheeling with the throttle off to help control the ATV during steep descents
The ECU has a Reverse Mode that monitors vehicle speed so higher engine RPM can be used when getting out of mud or loose soil in reverse mode
Sporty bodywork features sharply angled, high-clearance fenders
Suzuki’s plush T-shaped seat delivers rider mobility during sport or difficult terrain riding. Overall length is under 82 inches (208 cm) so the KingQuad fits into a 6.5-foot truck bed for easy transportation
