2012 Polaris Pro RMK 800. This sled is bone stock and has not been modified in any way. 163" track, all lugs are good. 1822 miles. All the mile have been in the mountains. This sled is in very good shape. It has had a new engine in 2014. I will post the miles at time of the engine replacement later or send me text and I will let you know. Tunnel storage bag and cover included.
