2025 Polaris PROSTAR S4 INDY ADVENTURE 137

2025 Polaris ProStar S4 INDY Adventure 137

The 2025 Polaris ProStar S4 INDY Adventure 137 brings four-stroke range and quiet to the Matryx chassis without giving up the way an INDY handles.

If you ride long days in cold weather and you are tired of two-stroke range, this is the answer. The ProStar S4 is a 998cc four-stroke twin — quiet, torquey off idle, and happy to sit at trail speed for hours without drinking the tank dry. On the Matryx chassis it rides like an INDY, not like a touring barge.
