What you get

The 137-inch track on the ProStar S4 INDY XC cuts through groomed trails without sacrificing maneuverability. Liquid-cooled 998cc two-cylinder with sequential port injection feeds forward momentum while the Matryx front suspension and Pro RMK rear keep the sled planted. Electric start, heated grips, and a fuel gauge come standard. F-N-R transmission gives you reverse. Moon Motorsports in Monticello stocks the ProStar lineup.
