- 2012 Polars Pro R 800 Switchy
i did this mod over the summer to my 2012 pro r with the front heat exchanger. Man does it make a difference. Was out with the boy on his 340 showing him a few things and my sled was consistently at 109-111F while putting along at 25mph. Did some long high speed pulls in the farmer's field and didn't get over 115F. This thing really works. Suggest anyone that has a cooling issue to do this.
