New chassis? No one ever called it a new chassis, it is an Axys chassis but it is highly refined in everyway, they have fixed basically every single complaint from years past. It is narrower, simpler, and has better fit and finish.
There are so many thing on the Polaris that just make sense about the way its built. Fewer parts (fasteners, hardware etc), shorter lighter wiring harness, shorter lighter intake tract (Cat intake... ? ), boards improved once again, bar setup once again improved, tunnel reimagined, stupidly simple belt drive, new lock and ride system, a gauge that track your friends, you can litterally set the temperature by the degree that you would like your warmers at. Theres a million little things that make so much sense on the Polaris, the Cat is the exact opposite.
