Wow Lenn, I think you might have opened a can of worms with that statement. I think you have the attention of every My 22 850 owner now.Here's what I was told by Polaris: 850 has Lighter flywheel, improved power boosting regulator, and a new map. After spending quite a bit of seat time on a demo 2022 850 129 VR1, I can confirm that it's quicker than my 2021 850-137 VR1. Spools up quicker and accelerates hard. Very impressive top speeds of speedo indicated 115+ MPH. It did this consistently. It easily walked by my 2021 in a drag race. And mine was studded with real studs. The Demo unit I rode had the Ice Ripper track. Mine has the 1.5 Storm.
