Yeah, teething issues. I wouldn't buy a first year Polaris product until I have enough money to afford that, and a newer one than I currently ride as a backup. But you're talking about one engine/clutch combination (Boost and P22), coupled with last year's track issue (series 8, mostly from sub-optimal drivers). On the other hand, I know several people who are still riding '19 850s with significant miles and no issues. Most Poos are pretty reliable, and the days of fixes needed out of the box (other than minor checks like clutch alignment) were mostly done by the time the AXYS came out. I'd put money on Poo 850s (not counting the Boost) being more reliable than Doo's, and they're worlds easier to work on. To each his own, but if Poos are half as bad as you think, they must ride circles around Doo to be worth it.
