SPORTIER 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 everyday tasks, you will find the KingQuad powering a rider onward. Across the board, our KingQuad lineup is an exceptional group of ATVs.

For riders who favor a sportier performance, the 2025 Suzuki KingQuad 400FSi features a five-speed manual-shift transmission and semi-automatic clutch. This engine is always willing as it cranks out an impressive amount of torque and has an incredibly wide powerband for exceptional performance on the trail or on the job. A high-performance iridium spark plug and refined Pulsed-secondary AIR-injection (PAIR) system help provide outstanding fuel efficiency, clean emissions, and impressive performance.

HIGHLIGHTS:
• The KingQuad 400FSi’s fuel-injected, 376cc, four-stroke, four-valve engine produces efficient power and driveablity.
• Suzuki’s class-leading fuel injection smooth’s power output and provides excellent cold starting
• Torque-sensing limited-slip front differential provides maximum traction and light steering when in 4WD mode.
• Winch-ready mounts and wire conduit makes winch installation simple.

ENGINE
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
Five-speed transmission with semi-automatic clutch with reverse allows the rider to select the ideal gear for maximum traction and fuel efficiency. Select 2WD or 4WD with the flip of a handlebar-mounted lever. The shaft drive system is reliable and durable and is nearly maintenance-free.

CHASSIS
Sporty bodywork features sharply angled, high-clearance fenders. Suzuki’s exclusive T-shaped seat delivers rider mobility during sport riding or tackling difficult terrain. It’s also plush for extended riding comfort. Overall length is under 82 inches (208 cm), so the KingQuad fits into a 6.5-foot truck bed for easy transportation.

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