Has anyone heard of a Polaris R-SX? If so, what is it? I couldn't find information on the Polaris website. I live in Eastern Idaho and Rexburg Motor Sports has a big billboard with this on it and haven't had time to go in and see what it is. I wondered if it was something that they came up with or if it was something direct from Polaris. Anyway, if anyone has any info on it that would be great. Thanks in advance.
