The 2025 Suzuki KingQuad 400ASi is a compact utility ATV built around familiar hardware rather than headline performance. Its $7,199 price buys a 376cc single, QuadMatic automatic transmission, selectable 2WD and 4WD, a differential lock and 10.2 inches of ground clearance. It is straightforward, easy to understand and backed by a long-running model family. The catch is that several newer competitors offer more power or towing capacity for less money. Our guide to reading ATV and UTV specs explains how these numbers affect daily use.
The 376cc air and oil-cooled single-cylinder engine makes about 26 hp. Power goes through Suzuki’s automatic QuadMatic CVT, so the rider can focus on throttle, braking and line choice rather than shifting. That combination is suitable for checking property, hauling light supplies and riding moderate trails at a sensible pace.
The engine is not a performance standout. The CFMoto CForce 400 makes 27 hp, while the Kawasaki Brute Force 450 4x4 reaches 38 hp. The KingQuad’s appeal is proven, predictable operation rather than strong acceleration. Buyers who regularly climb with a load or want a faster trail pace should consider moving up in output.
Drivetrain and trail manners
Selectable 2WD and 4WD let the rider keep steering lighter on firm ground, then bring in four-wheel drive when traction falls away. The listed differential lock is an important work feature because it helps when ordinary four-wheel drive cannot keep the front tires pulling evenly through mud or uneven terrain.
At 46.1 inches wide with a 50.2-inch wheelbase, the Suzuki remains compact enough for wooded routes and tight property access. Its 10.2 inches of ground clearance compare well with direct rivals. The machine weighs 606 lb, which is 11 lb lighter than the CForce 400 and 77 lb lighter than the Brute Force 450. That manageable size helps when changing direction at low speed or loading the ATV for transport.
Work capability: useful racks, limited towing
The KingQuad is a single-seat utility ATV with front and rear racks for tools, feed, hunting equipment and other daily cargo. Its 660 lb tow rating supports lighter trailers and routine property tasks, but it is the clearest place where the specification falls behind.
The Honda FourTrax Rancher 420 is rated for 848 lb, while both the CForce 400 and Brute Force 450 reach 1,050 lb. Anyone who regularly pulls a loaded trailer should take that gap seriously. The Suzuki remains useful, but it is better matched to lighter work than its rugged appearance might suggest.
Who it is for
The KingQuad 400ASi fits riders who want a compact, single-seat utility ATV with an automatic transmission and differential lock. It makes sense for acreage maintenance, hunting access and relaxed trail use, especially when outright speed is not a priority. Owners who value a mature design and prefer Suzuki’s straightforward approach may find that familiarity reassuring.
It is less suitable for frequent heavy towing, aggressive riding or buyers seeking the longest standard equipment list for the price. The dataset does not list power steering among its features, while the cheaper CForce 400 includes EPS. Rider effort and trim details deserve a close look during a test ride.
How it compares
The CFMoto CForce 400 costs $5,999, makes 27 hp and can tow 1,050 lb. It also lists EPS and carries 0.5 more gallons of fuel. The Suzuki counters with slightly more clearance, lower weight and a longer established reputation. Compare the CForce 400 and KingQuad 400ASi.
The Kawasaki Brute Force 450 4x4 costs $6,999 and makes 38 hp. It is narrower and can tow 1,050 lb, though it weighs 77 lb more and offers less clearance. The Kawasaki wins the output comparison, while the Suzuki is lighter and has the more mature platform. Compare the Brute Force and KingQuad.
The Honda FourTrax Rancher 420 costs $6,199, makes 27 hp and uses a five-speed automatic DCT rather than a CVT. It tows 848 lb but has only 6.9 inches of ground clearance. The Honda brings strong value and a legendary durability reputation. The Suzuki answers with 3.3 more inches underneath and a differential lock. Compare the Rancher and KingQuad.
Where it sits in the Suzuki lineup
The 400ASi is the entry point to Suzuki’s adult utility range. The KingQuad 500AXi costs $8,749 and adds a 493cc liquid-cooled single making 34 hp, power steering and a 1,322 lb tow rating. The KingQuad 750AXi costs $9,749 and raises output to 48 hp while retaining the same 1,322 lb rating. The 400 is lighter and cheaper, but stepping up makes sense for demanding workloads.
Price and value
At $7,199, the KingQuad 400ASi cannot rely on price alone. Every direct rival discussed here costs less, and two provide much higher towing capacity. Suzuki’s argument rests on its proven workhorse character, compact dimensions, useful clearance and uncomplicated QuadMatic drivetrain.
That can still be worthwhile for an owner who trusts the local Suzuki dealer and intends to keep the ATV for years. Buyers focused on maximum specification per dollar will find stronger paper value elsewhere. A test ride and a realistic assessment of towing needs should decide whether Suzuki’s mature design earns its premium.
Pros and cons
The good: compact dimensions, 10.2 inches of ground clearance, selectable 2WD and 4WD, a differential lock, manageable 606 lb weight and a proven utility-focused design.
The catch: only 26 hp, a modest 660 lb tow rating, no power steering listed and a $7,199 price above several better-equipped rivals.
The verdict
The 2025 Suzuki KingQuad 400ASi is a dependable-feeling utility ATV with a clear preference for simplicity over specification-sheet dominance. Its compact chassis, differential lock and generous clearance make it practical on property and trail. Its weak points are just as clear: towing capacity is limited, power is modest and the price is difficult beside newer value rivals. For riders who want a proven Suzuki and do not ask it to pull heavy loads, the 400ASi remains a sensible workhorse. Everyone else should compare carefully before paying the premium.
