Polaris, if your reading this and the 2016's are using the same weak shafts that you came out with in 2013 that needed the collar to hold them together...that's pretty sad. I owned a 2013 Pro RMK and never had a problem. However, when you post quarterly profits in the millions and totally redesign a sled with a new chassis, motor, shocks, suspension, track, gearing etc. how can you justify leaving the only known weak link. Hopefully no one gets hurt from this "band aid ". I know the old saying "if its not broke,don't fix it ", but this was broken on "some" so it did need fixing. When your trying to prove your quality control is as good or better than others this is embarrassing. The auto industry wouldn't get away with this. Please look at a permanent solution to this.
I did snowcheck a 2016, and I'm sure I won't have a problem with it, but there's still no excuse. I'm sure to get flamed on this one
Now someone delete this post so the "other" brands aren't on here trolling for any dirt to discredit the almost perfect sled lol
