No problems with the standard 800 RMK with extra cooler, stock shocks, aluminum overstructure, and aluminum rear bumper.
On the Pro RMK 800, You should expect that the clutch end of the driveshaft will need a collar also, and with or without a double collars, the driveshaft will eventually need full replacement due to long term fatigue on the glued joints. QD belt is hit and miss. Carbon fiber joints are problematic. Carbon fiber rear bumper is useless for towing. Carbon fiber overstructure may experience crushing failures. The tunnels are so light that they are deforming under 1st season use since the old integral foot rests are gone and have been replaced with a diced up and riveted cattle grating that provides no lateral rigidity to the lower edge of the tunnels. The Walker Evans shocks have been having problems for the over 200 crowd. But if you sell it after one season, you should do fine.
Just like others have stated, do not look too hard into what people write on here (or other internet sources). Everything that is a problem for one or two people automatically gets thrown into a category of "epidemic status"
To give an example:
I hit a tree at 20+ miles per hour 2 weeks ago on my 13 pro. Posted a pic of my a-arms ripped clean off and stated that it was due to the amazing engineering from Polaris that it did not wreck a bulkhead or any other costly parts other than 2 arms and a ball joint. Yet within minutes people were saying that it was a glue failure, soft a-arms, a problem with the cast lower arm end, and a few toted that I should have bought an Arctic Cat lol This being said everyone jumps to conclusions.
Its sad that so many on here read one horror story and instantly think they can chime in as if they do repetitive fatigue testing for Polaris. I don't know how all these people "know" for a fact what the life cycle of a certain part (that just came out this year) is going to be like.
Here's what I look at when purchasing a sled:
-How it handles
-What it weighs
-How easy it is to service/repair (lets face it if your actually riding your eventually gonna break something)
-Power is last in line because its all rider dependent. Ex: Keith Curtis can beat up on doo and cat in stock class with a sled that is clearly at a HP disadvantage.
Now to get back to the Pro fixes that you originally asked about.
I have an aftermarket collar only on the side of the drive shaft receiving torque, that wraps around the end to prevent it from ever coming out and after all the jumping I've done on this thing so far I feel confident in saying that issue is resolved. I'm not sure what whoisthatguy means about the tunnel deforming within 1 season. I normally have 1500+ miles per year on each of my sleds being jumped 100 ft+ and dropped off equally large cliffs with no such problems, and on my non jumping days I bash my sled in thru trees all day long, still nothing. Carbon overstructure...well I've never heard of any breaking other than from people on SW but thats just coming from one guy (me). Carbon bumper, yes it is not tow worthy off the carbon part, I only tow off the rear running board support and wrap it over the rear bumper side bracket so the loop is tight to the sled, never a single failure with towing 6 sleds out in 3 years so no big deal in my view. I will agree that the Walker Evans shocks are too soft for larger riders or people that like to jump a lot. Also I will add that it drives me crazy how loose the steering feels after a season (or less) of riding and it is fairly easy to break steering post bushings if you crank on the bars too hard when it gets steep in the trees (although it is nice that its a 10 mins fix and they are always warrantied. As far as the motor is concerned I have never had a single issue from 11 to now but would not recommend riding any brand of sled without a warranty. I ride with every brand out there and have seen all of them even barely off the showroom floor go down and have to be towed out.
All in all ride each sled as much as you can to feel em out, don't believe most "horror stories" because lets face it, if all these companies has something truly catastrophically bad, it would not be selling
