2023 Suzuki 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 are working hard or getting away from it all, the 2023 Suzuki KingQuad 400ASi helps you every step of the way. The fully automatic Quadmatic transmission has 2WD and 4WD 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 help provide outstanding fuel efficiency and clean emissions.

Features may include:

• Key Features

Powerful, fuel-injected, 4-stroke engine is easy on gas.

Fender-mounted shifter controls the QuadMatic transmission.

Rugged bodywork and full racks to tackle any task.

Large fuel tank and plush seat deliver extended, comfortable riding range.

Select 2WD or 4WD via a handlebar-mounted lever.

• Engine Features

The KingQuad 400ASi’s fuel-injected 376cc four-stroke, four-valve engine produces efficient power and driveablity.

Suzuki's class-leading fuel injection smooths 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).

• Transmission Features

The QuadMatic 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 reverse.

Select 2WD and 4WD 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.

• Chassis Features

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.

Independent front A-arm suspension offers smooth performance and remarkable ground clearance with 6.7 inches (170.1 mm) of wheel travel.

• Utility/Convenience Features

Dual 35-watt headlights (with high and low settings) are part of the distinctive KingQuad grille appearance. Bright tail light helps make the ATV visible in dark conditions.

Heavy-duty front and rear cargo racks let you take advantage of the ATV’s superb load capabilities. Wrinkle paint finish on the racks and front bumper is durable and scratch resistant.

12-month limited warranty. Longer coverage periods with other benefits available through Suzuki Extended Protection (SEP).
