Remember back when everything was Xtreme? Seems like everything was ‘Xtreme,’ from sports to cheeseburgers. Even Polaris went through an Xtreme phase, with the introduction of the 2011 Polaris Ranger RZR XP 900.
Here’s a look back at the video of the 2011 Polaris Ranger RZR XP 900, tagged by Polaris as the world’s first extreme performance sport Side x Side:

What was truly an extreme move for Polaris was when the ProStar engines started appearing in the ORV lineup (Ranger, RZR, Sportsman, and ACE). By 2015, Polaris’ entire lineup of Polaris ORVs were powered by ProStar engines.
Back when the 2011 Ranger RZR XP 900 was out, Polaris was relying on other manufacturers to provide engines for its ATVs and UTVs. But Polaris started to grow—fast—and began developing purpose-built four-stroke engines for its ORV machines. Here’s a look back to 2014, when Polaris was introducing its ProStar engines:

The ProStar engine were put into the Sportsman 550 and 850s, then the RZR 570. An 875cc in the RZR XP 900 was next, and then a 999cc engine was put into the RZR XP 1000. By 2015, Polaris’ entire lineup of Polaris ORVs were powered by ProStar engines.
