2004 Suzuki QuadSport® Z400

The 2004 Suzuki QuadSport Z400 (LT-Z400) holds a well-earned reputation as one of the most influential sport ATVs of its era. When it launched, it redefined the 400cc class with a level of performance and refinement that rivaled larger, more expensive machines. Suzuki borrowed heavily from its motocross and racing DNA, and the result was a machine that offered exceptional handling, responsive suspension, and a powerful yet reliable 398cc engine—all wrapped in a lightweight chassis designed for serious off-road fun.

The Z400’s combination of electric start, a wide-ratio 5-speed transmission with reverse, and a robust liquid-cooled DOHC powerplant gave it a unique edge over the competition. It was one of the first sport ATVs to offer motocross-inspired technology in a user-friendly platform that could perform on trails, dunes, or racetracks. Its fully adjustable suspension, durable aluminum components, and nimble geometry made it a go-to choice for riders seeking both agility and durability.

Over two decades later, the Z400 continues to be a favorite in the used ATV market thanks to its bulletproof reputation, easy access to aftermarket parts, and overall versatility. Riders still appreciate its comfortable ergonomics, predictable power delivery, and forgiving yet athletic nature. For new enthusiasts, it's a great way to enter the world of sport quads without sacrificing performance. For seasoned riders, it's a nostalgic machine that still holds its own against modern designs.
