DELIVERS IMPRESSIVE PERFORMANCE.

In 1982, Suzuki introduced the world’s first 4-wheel ATV. Today, Suzuki ATVs are everywhere. From the most remote areas to the most challenging tasks, you will 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 2025 Suzuki KingQuad 400ASi SE helps you every step of the way. The fully automatic QuadmaticTM 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 impressive performance.

HIGHLIGHTS:
The KingQuad 400ASi’s fuel-injected 376cc four-stroke, four-valve engine produces efficient power and driveablity.
Automotive gate-type gearshift lever lets you conveniently choose high or low range, neutral, or reverse.
Sporty bodywork features sharply angled, high-clearance fenders.

ENGINE
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.

TRANSMISSION
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. 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.

CHASSIS
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
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. LCD instrumentation includes speedometer, odometer, trip meter, hour meter, clock, fuel gauge and indicators for reverse, neutral, oil and FI (fuel injection).

• Armored Blue Gray

WARRANTY: 24-month limited warranty
