2025 Suzuki KingQuad 400ASi
In 1982, Suzuki introduced the world's first four-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, the Suzuki KingQuad lineup is an exceptional group of ATVs.
Whether you are working hard or getting away from it all, the 2025 Suzuki KingQuad 400ASi helps you every step of the way. The fully automatic QuadmaticTM transmission has 2WD and 4WD modes to manage 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:
- Engine
The KingQuad 400ASi’s fuel-injected, 376cc, four-stroke, four-valve engine produces efficient power and drivability.
- Transmission
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.
- Chassis
Independent front A-arm suspension offers smooth performance and remarkable ground clearance with 6.7 inches (170.1 mm) of wheel travel.
- Electrical
Dual 35-watt headlights (with high- and low-beam settings) are part of the distinctive KingQuad grille appearance. A bright taillight helps make the ATV visible in dark conditions.
- Body & Styling
Sporty Flame Red or natural Terra Green bodywork features sharply angled, high-clearance fenders while the full steel cargo racks help tackle any outdoors task.
- Additional
Suzuki’s 24-month limited warranty is much longer than other ATV warranties. Longer coverage and other benefits are available through Suzuki Extended Protection (SEP).
