I’m helping my bud research a new trail sled that he will be snow checking for Fall. He is a novice rider who will be riding almost exclusively the trail system in Manitoba……lakes and forests. He is on a budget. It seems like the 850 is pretty much the default, yet the 600R at 125 HP must have good jam and reliability? Looking at a Renegade or Backcountry model. Thanks for your input.
