Vehicle Information
Suzuki King Quad 400 ATV (2008-2026)
The Suzuki King Quad 400, produced from 2008 to 2026, is a robust and versatile ATV known for its reliability. It is powered by a 376cc four-stroke, air/oil-cooled (SACS system), single-cylinder engine with a Single Overhead Camshaft (SOHC) and four valves. This engine is valued for its efficient power delivery and impressive torque, though specific horsepower figures are not widely published. The most significant update for the King Quad 400 occurred in 2011, introducing Electronic Fuel Injection (EFI) and a digital speedometer, replacing the carburetor and analog instrument cluster. Since then, the 376cc engine has maintained its core design, benefiting from minor refinements to enhance performance and efficiency. Models are primarily offered in two transmission configurations: the 400ASi (Automatic, Fuel Injected) with a Quadmatic CVT transmission, and the 400FSi (Foot Shift, Fuel Injected) with a five-speed manual transmission. Special Editions (SE/SE+) and camouflage versions are also available, offering aesthetic upgrades. FAQ:
