2026 SUZUKI King Quad 400 4x4,

Meet the 2026 Suzuki KingQuad 400ASi in —a utility-sport ATV that looks ready to work before it even turns a tire. (And if you’re the type who likes choices, this model is also available in Terra Green and Flame Red.)



Thumb the electric start and the 376cc fuel-injected, single-cylinder 4-stroke wakes up with that confident, no-nonsense attitude you want when the trail gets long or the chore list gets longer. Its air/oil cooling and SOHC 4-valve setup keep things simple and durable, while the 9:1 compression and regular gas appetite make it easy to live with day to day.



Out on the move, Suzuki’s Quadmatic CVT takes the busywork out of shifting, and you still get the control you need with Hi/Low range plus a very welcome reverse for tight spots. When the terrain changes its mind, you can, too—thanks to selectable 4x2/4x4. Power goes down through a tough shaft drive to the wheels, giving you that solid, steady feel when you’re crawling, climbing, or cruising.



This KingQuad is built with practical confidence: a steel frame, brush guard, radiator guard, and a front bash plate with a full-length skid plate to help it shrug off the stuff that likes to jump up in your path. The stance feels planted with independent double A-arm front suspension and a rear swingarm with dual shocks, each offering 6.7 inches of travel to smooth out ruts and bumps.



Rolling on Carlisle AT 25-inch tubeless tires mounted to steel wheels, it’s sized right for real-world utility while still being trail-friendly. Up front, dual hydraulic discs deliver strong stopping power, backed by a rear drum brake and an Engine Braking System for extra control on descents.



With a comfortable one-piece vinyl seat, 33.1-inch seat height, 4.2-gallon fuel capacity, and handy touches like a fuel gauge and temperature warning light, the KingQuad 400ASi is ready for the kind of days that don’t stick to pavement—or to plans.
