Since 2003 XCR800s - Polaris have not had any of the aftermarket performance sleds like they used to back in the day. We have likes of BMP, D&D and a few high profile companies but they seem to work on mostly AC, Doos and Yamahas - Polaris seem to be left out performancewise. Does anyone know why we don't have Hot to Go or PSI or any of the aftermarket that knows how to make the new Polaris sleds to run and run against the DOOs, CATs and Yamaha? Only ones I see are the mostly the XCRs that is still competitive today. Anyone know the truth to this as why? WL .
