Vehicle Information
Polaris ATP 500 ATV (2004-2005)
The Polaris ATP 500 H.O. was a prominent utility ATV offered during the 2004 and 2005 model years. This robust all-terrain vehicle was powered by a 499cc liquid-cooled, single-cylinder, OHV, 4-stroke engine. While specific horsepower for the 2004 model isn't consistently listed, the identical engine in the 2005 ATP 500 H.O. produced 41 horsepower, indicating consistent performance across these years. The primary trim for the 500cc engine was the ATP 500 H.O. (High Output). No significant generation breaks or major engine changes occurred between the 2004 and 2005 models; the core specifications remained consistent. However, these models were part of a broader recall for Electronic Control Modules (ECM) in 2004.5 and 2005 Polaris ATVs, and charging system issues were noted, leading to redesigns in later models.
