Features May Include:

Engine Features

• The KingQuad 400Asi SE’s fuel-injected, 376cc, four-stroke, four-valve engine produces efficient power and drivability.
• 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.
• The Engine Control Unit (ECU) has slip control logic, which adjusts fuel injector duration and timing to improve drivability and grip in loose/slippery conditions.

Transmission Features

• 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.
• Automotive gate-type gearshift lever lets riders conveniently choose high or low range, neutral, or reverse.
• 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.
• Torque-sensing limited-slip front differential provides maximum traction and light steering when in 4WD mode.

Chassis Features

• 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 provide agile handling and plush riding.
• Dual front hydraulic disc brakes feature calipers with large, 34mm pistons and wide brake-pad surface areas for ample stopping power while providing outstanding durability. Lightweight and durable plastic skid plates are sturdy to withstand trail pounding, yet slippery to let obstacles easily slide under.
• 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.

Electrical Features

• LCD instrumentation includes a speedometer, odometer, trip meter, hour meter, clock, fuel gauge, and indicators for reverse, neutral, oil, and FI (fuel injection).
• Dual 35-watt headlights (with high- and low-beam settings) are part of the distinctive KingQuad grille appearance. Bright taillight helps make the 400ASi SE more visible in dark conditions.
• Automotive-style DC power outlet is included on the front fender.
• Winch-ready mounts and wire conduit make winch installation simple.

Body & Styling Features

• 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 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.
• Heavy-duty front and rear cargo racks let riders take advantage of the 400ASi SE’s superb load capabilities. Wrinkle paint finishes on the racks and front bumper are durable and scratch- resistant.
