2018 Suzuki KingQuad 400FSi

/
NOTHING'S BUILT LIKE A KINGQUAD

In 1983, 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'll find the KingQuad powering a rider onward. Across the board, our KingQuad lineup is an exceptional group of ATVs.

The 2018 Suzuki KingQuad 400FSi features a five-speed manual-shift transmission and semi-automatic clutch for those who favor a bit sportier performance. 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 great performance.

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 swingarm rear-suspension with 6.7 inches (170.1 mm) of wheel travel and twin shock absorbers provides agile handling and plush ride
  • 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 offers consistent traction in wet conditions, yet has a quiet, smooth ride on hard-packed trails
  • Lightweight and strong plastic skid plates, 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
