Vehicle Information
Polaris Worker 500 ATV (1999-2001)
The Polaris Worker 500, produced from 1999 to 2001, shared many specifications with its counterpart, the Sportsman 500, particularly its engine. During these years, the Worker 500 was equipped with a 499cc (or 498cc) liquid-cooled, 4-stroke, single-cylinder engine. For the 1999 and 2000 models, this engine typically produced approximately 32 horsepower. Although the Sportsman 500 introduced a "High Output" (H.O.) engine with 41 HP in 2001, there is no specific information indicating that the Worker 500 received this upgrade. Therefore, it is generally understood that the 2001 Worker 500 likely continued with the standard output of approximately 32 HP. The Worker 500 was a distinct model designation, with no multiple trim levels offered specifically for this period. General improvements were made across the broader Polaris 500cc ATV line, such as the Engine Braking System (EBS) becoming standard in 2000 and upgraded steering components for the Sportsman 500 H.O. in 2001, but their application to the Worker 500 is not confirmed.
