Real upgrades for legendary Z400...

SUZUKI has made a number of key improvements to the legendary LT-Z400 for 2009. It gains the fuel injection technology from the 450 racer as well as the R's sharper style bodywork and an extra inch of width. The electronic fuel injection gives the Z400 a smoother and quicker throttle response, improved starting and performance in a variety of conditions, and improved fuel efficiency and the ignition Engine Control Unit monitors throttle position, engine RPM and the rate of change of both. By deciding the optimum settings for volume and timing, the ECU also gives the ATV improved traction.
The new QuadSport's engine updates include a change in cam profile and timing, an intake port redesign, change in internal muffler structure and shorter exhaust header pipe, all designed to improve low to mid-range power output while maintaining the Z's strong top-end power.
Externally, the chassis has been redesigned to be more accessible, functional and user-friendly. The front track has been widened by an inch, and the caster, camber and trail have all been changed. All of these modifications give the Z400 a lighter steering feel and more sure-footed handling.
Changes in both the front and rear suspension offer the rider a firmer response, plus a plush feel resulting in a comfortable, enjoyable ride.
