Vehicle Information
Polaris Centurion Indy 500 Snowmobile (1981)
The 1981 Polaris Centurion Indy 500 was a groundbreaking snowmobile, marking a significant step for Polaris. It combined the powerful 500cc liquid-cooled triple-cylinder engine, known for its high-output performance, with the innovative Indy chassis featuring an independent front suspension. This model was a new introduction for 1981, offering riders a blend of power and advanced handling. While celebrated for its performance potential, some noted its heavier feel compared to lighter competitors. For the 1981 model year, the Polaris Centurion Indy 500 was offered as a singular model without distinct trim levels. It represented the first time Polaris integrated a three-cylinder engine into the Indy chassis, which had debuted the previous year. This specific configuration was unique to 1981. In 1982, the "Centurion" name was dropped, and the model became simply the "Indy 500." Further, in 1983, the engine displacement increased to 600cc, leading to the "Indy 600."
