Engine Features

Compact, 90cc, four-stroke, single cylinder, air-cooled engine has been designed for durability and low maintenance.

Suzuki Composite Electrochemical Material (SCEM) cylinder, derived from Suzuki's high-performance, GSX-R sportbikes, provides durability, weight reduction and superior heat dissipation.

Smooth running, multi-plate cam chain lets the engine operate quietly. Easy-access oil filter and oil strainer cap reduces service time.

Clean-burning four-stroke engine complies with federal Environmental Protection Agency (EPA) emissions regulations.

The 2025 QuadSport Z90 is eligible for California off-highway vehicle (OHV) registration.

Spark-arrestor equipped muffler is environmentally friendly, yet has a pleasant exhaust note.

Large 1.6-gallon (6.0-liter) fuel tank provies long riding time. A vacuum-operated fuel petcock automatically stops fuel flow when the engine’s not running.

A keyed ignition switch lets grown-ups decide when the action begins and ends.

Simple, screw-type throttle limiter allows adult supervisors to limit the maximum power delivery to suit the rider's ability.

Speed-limiter collar in the automatic clutch limits top speed to 15 mph. It can be removed to increase top speed as the rider gains ability.

Includes an easy electric starting system plus a standard back-up recoil starter.

Smooth-running CVT automatic transmission provides easy operation and allows the rider to focus on riding instead of shifting.

Chassis Features

Child-size (Y-12) controls for easy operation.

Single A-arm front suspension with twin, independent shock absorbers and single-shock rear suspension provide long wheel travel for a smooth, comfortable ride.

Rear axle shaft has double oil seals for performance and reliability.

Headlamp style front piece is detachable to achieve the sporty look of the QuadSport Z400.

Modern styling with full floorboards creates a big Quad look that also features new yellow bodywork with coordinated graphics.

Front, side, and rear reflectors improve the ATV’s visibility to other riders.

Large-diameter, semi-sealed front drum brakes and single fully sealed rear drum brake provide strong braking performance.

One-piece, eight-inch wheels with tubeless tires provide a smooth comfortable ride.

Strong, high-rigidity steel frame is sturdy and compact.

The low seat height of just 25.6 inches makes it easy for the rider to get on and operate the ATV.

Suzuki T-shaped seat design is similar to the QuadSport Z400’s for smooth weight transition and a comfortable ride. The seat is easy to remove for service.

Easy to remove for service, the seat has a durable black cover that complements the ATV’s graphics package.

Competition-inspired bodywork features Champion Yellow bodywork with blue, black, and red graphics.

ATVs are not toys. Serious injury or death can result from improper use of ATVs. Your youngster’s safety will depend on you taking a "Safety First" approach to ATV riding. The QuadSport Z90 may be used only by those aged 12 and older. Always supervise riders under the age of 16. All other Suzuki ATVs may be used only by those aged 16 and older. Even though your child may be the right age, you need to be sure that he or she has the size, strength, skills, and judgment to operate the ATV safely. The SVIA publication "Parents, Youngsters & ATVs" (included with products and available through your dealer) contains guidelines that can help you determine if your child is ready to ride an ATV.
