in the fall i sold my 2010 polaris assault 800 rmk 146". and bought a 2012 pro rmk 800 155". Just wondering if anyone is havin problems with this sled, its got 500 miles on it now and still going strong. previous owner put 480 miles on in mountains, so its still clutched for mountains. What should i go with for color of spring and weights for saskatchewan riding? Thanks!!
