The QuadSport Z400 was first introduced in 2002 as a high-performance sport ATV featuring running capability delivered with it’s 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 QuadSport Z400’s high performance quickly won wide popularity; the model presented to many customers around the world the enjoyment of ATV riding, from sport rides to competition use.
The QuadSport 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 customers as a user-friendly, higher performance all-round sport ATV
Now, six years after its debut, the QuadSport Z400 unveils a new form and function design to bring about exciting evolution in sports ATVs.
While keeping intact it’s basic concept of offering sport ATV riding enjoyment to a wide range of customers, the latest QuadSport Z400 features various QuadRacer R450-derived upgrades – fuel injection, ECM settings for more traction and aggressive styling – for higher performance and more user convenience.
Details & Features
New Features
- All-new Suzuki fuel-injection system features a 36mm throttle body and 12-hole injector that delivers the fuel/air mix in an efficient fine-mist spray pattern
- Engine Control Unit uses a 16-bit CPU and a 96-kilobyte ROM unit. The system is programmed to obtain improved traction by selecting the optimum injection volume, injection timing and ignition timing based on throttle position, engine rpm, and other data monitored
- New styling reflects the powerful attitude of the QuadRacer R450, including the sharp fenders, the overall slim design and the removable headlight
- The chassis's rigidity balance is changed to improve handling stability, chassis strength and overall performance, particularly in rough terrain
- Front track is widened by 25mm to improve overall handling stability feel
- The footpegs are now 46mm wide - same as the QuadRacer R450
Key Features
