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

Front track is widened by 25mm to improve overall handling stability feel

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

The footpegs are now 46mm wide - same as the QuadRacer R450

The new 2009 Suzuki QuadSport Z400 is re-engineered for high-performance off-road four-wheeling with smooth power-output and throttle response from Suzuki fuel injection

Compact & lightweight 398cc 4-stroke, single-cylinder, liquid-cooled Dual Overhead Cam engine with counter- balancer tuned for tractable power over a wide rpm range

Convenient electric start system includes Start-In-Gear feature - electric start system and CDI ignition are powered by compact maintenance-free battery

Dry-sump lubrication system allows a compact crankcase and minimal engine height for optimum engine placement - oil tank is frame-mounted in front of the exhaust head pipes

Liquid-cooling system with high-capacity radiator and thermostatically controlled cooling fan provides consistent engine operating temperature

Five-speed transmission with cable-operated clutch includes an easy-to-use reverse gear system: turn the fender-mounted knob and shift to reverse using the gear shift lever

Long-travel, independent double A-arm front suspension with fully adjustable, piggyback reservoir-style shock absorbers - provides 8.5 in. of wheel travel

Linkage-type rear suspension features fully adjustable, piggyback reservoir-style shock absorber with 9.1 in. of wheel travel, plus 10.4 in. of ground clearance

Dual 30/30W, vertically-mounted halogen headlights provide a bold look and bright illumination - large 5/21W taillight/brake light combination

Front brake lever position adjustment mechanism is changed to the same system used on the high-performance QuadRacer R450, making brake adjustments much easier.

Large 2.5-gallon fuel tank with two mounting points for quick removal and simplified maintenance

Large 6.9 inch dual front disc brakes and single 8.6 inch rear disc brake

Lightweight aluminum alloy wheels (F: 10.0 x 5.5, R: 9.0 x 8.0), and radial tires (F: 22 x 7-10, R: 20x10-9), for reduced unsprung weight

Lightweight, high tensile steel-alloy frame and removable steel sub-frame, plus aluminum swingarm

Rear axle shaft taper is changed to heighten rigidity balance and provide optimum performance in conjunction with changes made to front track.
