The PZ480 powerplant produces approximately 75 to 85 horsepower with a peppy two-stroke powerband, factory oil injection eliminating pre-mix fuel preparation, and rotary valve induction for efficient cylinder filling. The lightweight chassis weighing approximately 440 pounds wet provides nimble handling on packed trail snow with responsive steering. The front suspension employs independent A-arm geometry with adjustable coil-over shocks while the rear evolved from basic rail designs to the ProAction Plus system featuring progressive rate springs and Hy-Fax slide rails. The CVT clutch system provides seamless power delivery through a drive chain enclosed in a sealed chaincase to the drive axle and track.
