The QuadSport Z400 was first introduced in 2002 as a high-performance sport ATV featuring powerful running capability delivered with its liquid-cooled DOHC engine – the first in its class – and other advanced designs, along with cutting edge styling.
As soon as it appeared on the market, the quad sport Z400’s high performance quickly won wide popularity; the model presented to many customers around the world the enjoyment of sport ATV riding, from fun sport rides to competition use. The QuadSport Z400 powerfully proved itself as a sport model in ATV Motocross. In 2004, the Z400 became, at the hands of team Suzuki/Yoshimura rider Doug Gust, the first 4-stroke ATV to win the ATVA pro class championship.
With the introduction of the race-ready QuadRacer R450, the QuadSport Z400 was no longer the top choice as a base machine for competition ATVs; Still, the model continued to win strong support from consumers as a user-friendly, high-performance all-round sport ATV. Now, six years after its debut, the QuadSport Z400 in 2008 unveils a new form and function designed to bring about exciting evolution in sport ATVs.
While keeping intact its basic concept of offering sport ATV riding enjoyment to a wide range of customers, the latest QuadSport Z400 features various QuadRacer 450-derived upgrades – fuel injection, ECM settings for more traction and aggressive styling – for higher performance and more user convenience.
