• Lightweight and durable plastic skid plates are sturdy to withstand trail pounding, yet slippery to help obstacles slide under easily.

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

Engine Features

• The KingQuad 400FSi’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.
• The Engine Control Unit (ECU) has slip control logic, which adjusts fuel injector duration and timing to improve rideability and grip in loose/slippery conditions.
