Why would Polaris eliminate those parts. Actually that Polaris rear end has less moving parts then the R Motion and 10 times the comfort.....so what's your point?.....And the XCR 800 doesn't explode like 30% of the 850's built. Also the XCR is $3000 bucks cheaper and 10 times the sled.....Doo's day are limited......the 850 like the Mach Z 1000......boom!.... Lol
Funny the same weekend you rode that XCR I rode a 1200 R Motion.... No comment.....other than it would make a nice groomer...needs an 8 track player to be up to date.
