Features may include:

Engine & Drivetrain

Maximum efficiency

The rugged OHV liquid-cooled, fuel-injected 420 cc longitudinally mounted engine allows direct driveshaft alignment to both front and rear wheels for maximum drivetrain efficiency.

Broad Powerband

Overhead-valve design provides compact engine dimensions for improved ground clearance while maintaining a broad, easy-to-use powerband.

Reduced vibration

Rubber-cushion engine mounting and gear-driven counter-balancer reduce vibration.

Easy start, fuel efficient

Convenient electric starting, with an automatic internal-decompression system, gets you going quickly. Also equipped with a recoil starter as back-up. The recoil will start the ATV even with a completely dead battery. Programmed Fuel Injection (PGM-FI) system improves power delivery and throttle response, and increases fuel efficiency for extended range.

Chassis & Suspension

Double-cradle steel frame

Double-cradle steel frame developed with Computer Aided Engineering features increased stiffness for even more precise handling and a smoother ride.

Adjustable suspension

Adjustable spring preload featured on all shocks allows suspension tuning to match varying loads and riding conditions.

Precise handling

Tough, 24-inch diameter front and rear tires provide excellent ground clearance of 183 mm (7.2 in) while maintaining great handling characteristics. Front and rear suspension feature 170 mm (6.7 in) of travel at both ends for a plush and controlled ride.
