I have a 2012 Pro RMK 163 Retro with 665 miles on it. Sled is in excellent condition. Sled is stock for the exception of a Polaris heavy duty front bumper, a Holtz racing aluminum rear bumper and Polaris skid plate. Want to trade for same year Nytro MTX 162 with comprable miles. Would consider a 2010 or 2011 with some cash to boot. Sled must be in excellent condition. The Pro's a great sled but am looking for a fourstroke to eventually turbo.
