2026 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 2026 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:

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

• Suzuki Advanced Cooling System (SACS) uses an oil cooler and thermostat-controlled cooling fan to shed engine heat during hard work or cargo hauling.

• 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.

• 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.

• Select 2WD and 4WD with the flip of a handlebar-mounted lever. The shaft drive system is dependable and durable and is almost maintenance-free.

• Automotive gate-type gearshift lever lets you conveniently choose high or low range, neutral, or reverse.

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

• A swingarm rear suspension with 6.7 inches (170.1 mm) of wheel travel and twin shock absorbers provides agile handling and plush riding.

• Large, 25-inch Carlisle® tires with aggressive tread offer consistent traction in wet conditions, yet make for a quiet, smooth ride on hard-packed trails.

• 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.

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

• Automotive-style DC power outlet is included on the front fender.

• 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.

• 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.

• 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.
