800 or 800s

Hey, new guy here. I’m currently looking at buying a 2009 rzr 800. The seller says that it is the "S" model but i noticed it dosent have the fox shocks, just factory polaris shocks. It is wider then a regular 800 so I’m not sure what it is! Is there any other way for me to tell which one it is? It is listed on Craigslist in the New York, Long Island section.

It has lots of aftermarket stuff but want to make sure is is actually an 800s.
Thanks for any help!!
