There's better informed peoples than I but from what I understand, the issues on the 850 were the earlier releases... So I would make sure the VIN isn't one of those... But I'm a Catman so the Poo guys can best guide youWe ride mainly trails and am really looking for reliability. I have had no issues with 800 SB 7,000 miles, but I have an opportunity to get a newer 2019 129" with 850. Is it worth the switch? Any ideas, concerns with 850?
Other improvements to 850 include better motormounts, Better wiring. Good coolant temp sensor with integral wiring versus problematic one with separate wiring used on 2020. 2020 also has leaner fuel delivery and it creates low rpm issues in some sleds. 2019 also had same problems on certain sleds. Several reflashes with mixed results. My own never had any of those issues and no reflashes needed. You get a better 1215 drivebelt on the 850 also. Different clutch face angles. 27 deg on 800, 28 deg on 850.Thanks for the notes. Yes, new one low miles, 2 more years on warranty, well maintained. Same original owner as 15 SB. We ride trails in LP as well, so nothing crazy, just cruising and looking for smooth ride, although tough to beat 137 SB and lower op temp when snow is scarce. thanks again.
