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.

Features may include:

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

The QuadmaticTM transmission is a fully automatic, CVT (continuously variable transmission) with selectable high/low sub-transmission and reverse helping provide maximum traction and fuel efficiency.

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

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

The unique Armored Blue Gray bodywork features sharply angled, high-clearance fenders while the full steel cargo racks help tackle any ranch or outdoors task.

Suzuki’s 24-month limited warranty is much longer than most ATV warranties. Longer coverage and other benefits are available through Suzuki Extended Protection (SEP).
