Features

Chassis Features

  • 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.
  • Independent front A-arm suspension offers smooth performance and remarkable ground clearance with 6.7 inches (170.1 mm) of wheel travel.
  • A swing-arm rear suspension with 6.7 inches (170.1 mm) of wheel travel and twin shock absorbers provides agile handling and plush riding.
  • Dual front hydraulic disc brakes feature calipers with large, 34mm pistons and wide brake-pad surface area for increased stopping power and outstanding durability.
  • 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.
  • The tires are mounted to rugged steel wheels powder-coated with a durable matte black finish.
  • Lightweight and strong plastic skid plates are sturdy to withstand trail pounding, yet slippery to let obstacles slide below.

Engine Features

  • 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, 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.
  • Push-button electric starting has a start-in-gear function—when the rear brake is applied—allowing starting without shifting to neutral (as conditions permit).
  • 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.
  • Highly efficient iridium spark plug contributes to better combustion, cleaner emissions and longer plug life. Engine starting under low temperature is also improved.
  • Pulsed-secondary AIR-injection (PAIR) system and catalyst-equipped exhaust system help the ATV meet emission standards while maintaining a high level of performance (eligible for California red-sticker registration).

Key Features

  • Powerful, fuel-injected, 4-stroke engine is easy on gas.
  • Durable manual transmission with semi-automatic clutch.
  • Select 2WD or 4WD via a handlebar-mounted lever.
  • Large fuel tank and plush seat delivers extended, comfortable riding range.
  • Rugged bodywork and full racks to tackle any task.

Special Features

  • Minimum Operator Age: 16 Years Old

Transmission Features

  • Five-speed transmission with semi-automatic clutch with reverse allows the rider to select the ideal gear for maximum traction and fuel efficiency.
  • Five-speed transmission with semi-automatic clutch with reverse allows the rider to select the ideal gear for maximum traction and fuel efficiency.
  • Torque-sensing limited-slip front differential provides maximum traction and light steering when in 4WD mode.
  • High/low selectable sub-transmission provides wide-ranging versatility.
  • Automotive gate-type gearshift lever lets you conveniently choose high or low range, neutral or reverse.
  • The ECU has a Reverse Mode that monitors vehicle speed, so higher engine rpm can be used when getting out of mud or loose soil in reverse mode.

Utility / Convenience Features

  • 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.
  • Winch-ready mounts and wire conduit makes winch installation simple.
  • Large, 4.2 gallon (16.0 L) fuel tank provides outstanding riding range.
  • Full floorboards with integrated raised footpegs provide protection.
  • A variety of Suzuki Genuine Accessories are available, including winches, windshield, front and rear bumpers, snowplow, aluminum skid pans, rack extensions, utility box, and more.
  • 12-month limited warranty
