Known for its fuel-injected efficiency, selectable 4WD system, and legendary Suzuki build quality, the KingQuad 400ASI remains a top choice for ranchers, trail riders, landowners, and powersports enthusiasts worldwide.
At bansheebikesusa.com, we specialize in performance machines — from Yamaha Banshees to premium ATVs and sport bikes — and the KingQuad 400ASI fits perfectly into our lineup as a no-nonsense, work-ready ATV with proven long-term reliability.
ENGINE & FUEL-INJECTED PERFORMANCE
Powering the 2018 KingQuad 400ASI is a 376cc liquid-cooled, single-cylinder engine equipped with Suzuki Fuel Injection (SFI). This system delivers consistent throttle response, smooth power delivery, and easy cold starts in all conditions — from hot summer trails to cold early-morning workdays.
Unlike carbureted ATVs, the KingQuad 400ASI automatically adjusts for altitude and temperature changes, making it ideal for riders who work or ride across varied terrain.
SELECTABLE 2WD / 4WD SYSTEM
The ASI (Automatic Shift, Independent suspension) model features Suzuki’s push-button selectable 2WD / 4WD, giving riders instant control over traction. Whether navigating muddy job sites, rocky trails, or snow-covered paths, the KingQuad adapts instantly to changing ground conditions.
This system improves safety, reduces rider fatigue, and extends drivetrain life by allowing 2WD operation when full traction isn’t needed.
INDEPENDENT SUSPENSION & HANDLING
With independent double A-arm suspension front and rear, the KingQuad 400ASI offers a smooth, controlled ride even on uneven terrain. The suspension setup absorbs bumps effectively while maintaining excellent ground contact, improving both comfort and traction.
The compact chassis and balanced weight distribution make it easy to maneuver in tight trails, wooded areas, and work zones.
DURABILITY & WORK-READY DESIGN
Suzuki engineered the KingQuad 400 for longevity. The sealed drivetrain components, robust frame, and high-quality plastics ensure it withstands years of use. Front and rear cargo racks allow you to haul gear, tools, feed, or supplies, making it equally capable as a work ATV or recreational machine.
