Vehicle Information
Arctic Cat Sno Pro 500 Snowmobile (2010-2014)
The Arctic Cat Sno Pro 500, produced from 2010 to 2014, was a performance-oriented snowmobile designed for trail use, built on a race-bred chassis. Throughout these model years, it consistently featured a 499cc liquid-cooled 2-stroke twin engine, delivering approximately 85 horsepower, equipped with clean-burn electronic fuel injection (EFI). There were no distinct sub-trims offered; the primary variations were color options. While the core engine and chassis remained consistent, notable updates occurred. The 2010 model, upon its introduction, experienced an engine loading issue at idle, which Arctic Cat addressed with an ECU re-program. For 2011, significant changes were implemented: the 1.25-inch snocross track was replaced with a 1-inch Hacksaw track to increase top speed, the front sway bar was removed, and stiffer front springs were added to improve handling and reduce ski lift. An additional ECU reflash further refined engine performance. The 2012-2014 models were largely carryovers, maintaining the 1-inch track lug height and core specifications from 2011, with no major mid-cycle generation or engine changes. FAQ:
