Built primarily for work and recreational use on farms or large properties, this ATV offers a reliable and simple approach to terrain management with enough power to handle tasks without overwhelming novice riders.
The KingQuad 400 ASi emphasizes durability and ease of maintenance, featuring a single-cylinder, 376cc engine with fuel injection that balances performance with efficiency. It’s suited for riders who need a machine that can perform consistent work without the complexity or high maintenance costs of larger, more advanced models. Its intuitive CVT transmission and selectable 4×2 or 4×4 drive modes give users control in a variety of conditions, whether on soft ground or hilly terrain.
This model’s overall character is one of practical reliability with a focus on user-friendly operation. Its independent double A-arm front suspension and swing arm rear suspension provide a smooth ride over uneven surfaces, and the 9.8-inch ground clearance ensures it can handle rougher paths without getting stuck. The KingQuad 400 ASi stands out within its segment because of its balanced mix of basic features, affordability, and Suzuki’s reputation for longevity, making it a strong choice for those who prioritize workhorse toughness in a simple package.
Performance & Powertrain
Pull up the throttle and you’ll notice the 376cc single-cylinder engine delivers a steady flow of power suited for hauling gear across tough terrain or performing work tasks. Its air and oil cooling system helps maintain consistent temperatures during extended use, reducing the risk of overheating under load. Fuel injection ensures reliable starts and efficient fuel delivery, giving the KingQuad 400 a responsive feel in various conditions.
This engine’s output is in line with other utility quads in its class, offering enough torque for trail work and light towing without feeling abrupt or overpowered. The power delivery is smooth thanks to the CVT transmission, which keeps acceleration predictable and easy to control. The automatic transmission shifts smoothly through its range, allowing riders to focus on steering and navigating rather than shifting gears.
The driveline offers a choice between 2WD and 4WD modes, making it adaptable for different tasks. When tackling loose gravel, muddy trails, or inclines, engaging 4WD provides extra traction. The combination of the engine’s size and the selectable drive modes makes this machine suited for homeowners, small farm operators, or those needing a reliable workhorse for light-duty tasks. Its powertrain strikes a balance between manageable performance and enough grunt to get work done without feeling cumbersome or excessive.
Suspension & Handling
Pull up the throttle and the Suzuki KingQuad 400 ASi shows its ability to handle a variety of terrains thanks to its independent double A-arm front suspension with 6.7 inches of travel. This setup provides a smooth ride over uneven ground, making it suitable for trail riding and light off-road work. The same amount of travel at the rear, combined with swing arm suspension, helps absorb bumps and impacts when hauling gear or navigating rougher terrain.
Braking performance relies on dual hydraulic disc brakes at the front, which offer strong stopping power and consistent feel, even when descending steep inclines or carrying heavy loads. The rear drum brake, while not as immediate as the front, still provides adequate control for most utility tasks and trail riding. When combined with the suspension design, these brakes help maintain stability and control across different riding conditions.
The tire setup features Maxxis AT tires with 25-inch diameters, front tires measuring 8 inches wide, and rear tires at 10 inches wide. These tires are suited for a mix of trail, hardpack, and mildly rough terrain, offering a balance of grip and durability. The wider rear tires improve traction during hauling or climbing moderate inclines, while the front tires help maintain steering precision and stability during directional changes. the suspension, brakes, and tires work together to provide predictable handling and confidence across a variety of work and trail environments.
Dimensions & Ergonomics
With a length of 6.76 feet and a width of 8 inches, this ATV is designed to fit comfortably in a standard pickup truck bed or small trailer, making transportation simple. Its height of 48 inches keeps it manageable for riders of varying heights without feeling top-heavy or unstable during operation.

Notable Features
If you’re planning to work in challenging terrain or need reliable performance for long hours, you’ll want to know about the features that set the 2015 Suzuki KingQuad 400 ASi apart from its competitors and earlier models. Suzuki equips this ATV with an electronic fuel injection system, an upgrade from carbureted setups found on many base trims. This system provides consistent throttle response and improves cold starts, making it a valuable addition for users who spend significant time outdoors in varying conditions.
Another standout feature is the inclusion of a selectable two- or four-wheel drive system, allowing riders to switch modes on the fly depending on trail conditions or load. This flexibility enhances off-road capability without the complexity of locking differentials or manual transfer cases. It provides a tangible benefit over simpler models that only offer single-mode drive, especially when tackling uneven or slippery surfaces.
The KingQuad 400 ASi also benefits from a fully automatic CVT transmission, which simplifies riding for beginners and reduces fatigue during extended use. Combined with its sturdy air-oil cooled engine, this transmission ensures smooth acceleration and deceleration, making it easier to operate in demanding environments. While it maintains the essential features expected at this price point, these upgrades improve the overall riding experience by blending reliability with user-friendly technology.
Pricing & Value
What stands out here is the $6,499 MSRP of the 2015 Suzuki KingQuad 400 ASi, positioning it firmly in the entry-level utility ATV market. This price appeals to buyers who want basic, reliable performance without paying a premium for high-end features or luxury trims. The KingQuad 400 ASi is designed for those seeking simple utility, such as farmers, property owners, or hobbyists who need something affordable but functional.
Compared to other entry-level utility ATVs, the KingQuad 400 ASi offers a balanced package that emphasizes simplicity and durability.
