2027 POLARIS PROSTAR S4 INDY XC 137 7S - INDY RED<\/strong><\/span><\/p>\n

FOUR-STROKE POWER. XC TRAIL PERFORMANCE.<\/strong><\/p>\n

The 2027 Polaris ProStar S4 INDY XC 137 combines the smooth, easy-to-ride character of the ProStar S4 4-stroke engine with the rider-focused handling of the Matryx platform.<\/p>\n

Its 998cc twin-cylinder engine, F-N-R transmission and 137\" Cobra track create a package designed for confident trail riding, while the PRO-CC rear suspension and Polaris TS shocks provide controlled performance over changing trail conditions.<\/p>\n

This Red\/White 7S-equipped model also brings RIDE COMMAND navigation and connectivity to the INDY XC, along with electric start, Smart Warmers and practical trail equipment.<\/p>\n

WHY BUY THE PROSTAR S4 INDY XC 137?<\/strong><\/span><\/p>\n

Polaris TS shocks provide adjustable suspension performance, and the 1.35\" Cobra track is designed for spirited trail riding with a balance of grip and acceleration.<\/p>\n

For riders who want additional technology on the trail, the 7S RIDE COMMAND display adds integrated navigation, trail mapping and Group Ride capabilities.<\/p>\n
