2027 Polaris ProStar S4 INDY SP 137 sport side-by-side from Polaris, right-side studio view

What you get

The 998cc liquid-cooled twin delivers consistent power on groomed trails without the weight penalty of larger displacement. Front travel hits 9.5 inches for bump absorption, and the Matryx front suspension with PRO-CC rear keeps the sled composed in variable snow. Sequential port injection means no fuel surprises, and the 11.5-gallon tank runs the distance. Electric start, smart warmers, and RCA outlet come standard. Moon Motorsports stocks the 2027 ProStar S4 INDY SP 137. See dealer for MSRP.
