Performance & Powertrain
With 376cc of displacement, the single-cylinder engine on this utility ATV strikes a balance between torque delivery and fuel efficiency. Designed for moderate workloads, it produces enough power to handle tasks like hauling supplies or navigating rough terrain without the abruptness associated with larger engines. The air and oil cooling system helps maintain consistent operating temperatures under extended use, which is critical during prolonged work sessions or in hot climates.
The fuel system employs electronic fuel injection, which provides more precise control over fuel delivery compared to carbureted systems. This improves throttle response and fuel economy, especially in variable conditions. The fuel injection system also simplifies cold starts and enhances overall engine stability, making it suitable for users who rely on the vehicle for daily chores or light work tasks.
The transmission features a continuously variable transmission (CVT), which eliminates traditional gear shifts in favor of a belt-driven system that adjusts smoothly to engine load and speed. This setup offers smooth acceleration and simplifies operation, allowing the rider to focus on steering and handling rather than gear changes. The selectable 4×2 and 4×4 drive modes provide flexibility for different terrains and tasks. Engaging four-wheel drive enhances traction in muddy or uneven conditions, while switching back to two-wheel drive conserves energy on smoother surfaces.
the powertrain configuration emphasizes ease of use and reliability, making it suited for recreational riders and light-duty work. The engine’s relatively modest displacement pairs with the CVT to produce a predictable power curve, favoring low-end torque for pulling and maneuvering rather than high-speed performance. This setup benefits operators who prioritize control and efficiency over outright speed or high horsepower, aligning with the machine’s utility focus.
Suspension & Handling
With 6.7 inches of suspension travel at both the front and rear, the suspension system on the Suzuki KingQuad 400 ASi is designed for a balance between comfort and stability across a variety of terrains. The independent Double A-Arm setup at the front allows each wheel to move independently, helping to maintain tire contact on uneven surfaces such as loose dirt, rocky trails, or rutted paths. This configuration minimizes body roll during cornering and enhances steering response, which is especially useful for trail riding or light work in rough conditions.
The rear suspension employs a swing arm with an identical 6.7-inch travel, contributing to consistent handling characteristics and predictable performance when traversing over rocks, roots, or other obstacles. The equal travel distribution between front and rear ensures that the machine maintains a balanced attitude, reducing the likelihood of bottoming out under moderate load or impact. Such design choices favor a smooth ride over varied terrain, though quick, sharp impacts can still challenge the system due to the travel limitations inherent in a utility-focused ATV.
The braking setup features dual hydraulic disc brakes at the front, providing strong and fade-resistant stopping power with precise modulation. This is advantageous on steep descents or when carrying heavy loads, where controlled braking is critical. The rear drum brake offers a simple, durable solution for rear stopping power, which suffices for the intended utility tasks but may not match the responsiveness of disc brakes. Tire specifications include Carlisle AT 25 x 8-12 tires at the front and Carlisle AT 25 x 10-12 at the rear, providing a good compromise between grip and durability in off-road environments. The larger rear tires improve traction and flotation on loose soils, while the narrower front tires aid steering input and maneuverability on hard-packed surfaces.
Dimensions & Ergonomics
At 81.1 inches in length, the Suzuki KingQuad 400 ASi fits comfortably within the dimensions of a standard pickup truck bed, making it suitable for transportation without disassembly. Its width of 45.1 inches provides a stable footprint, especially important when traversing uneven terrain or carrying cargo. A height of 48 inches keeps the machine manageable for riders of varying heights while maintaining a solid center of gravity for stability.
- Wheelbase measures 50 inches, contributing to predictable handling and ride comfort.
- Ground clearance of 9.8 inches allows for moderate obstacle clearance without risking ground contact during normal trail riding or farm chores.
