900 RMK, not so bad...
The 900 Polaris Rmk was one of the most over engineered sleds ever built at the time. However, after some intial problems and some very poor support from Polaris, it never had the opportunity to get refined and fully dialed by the Factory guys, much less proper training of the Service Departments or Mechanics. After two seasons of problems the sleds were mothballed, or "temporarly shelved".
It was too bad that it had "issues" from release, but it is most unfortunate that they did not stick with it for one more season, for they would have gotten on top of the issues and had a great sled.
As the above poster mentioned, check in on the 900 Polaris section for the full scoop and details.
Many of the original 900 owners have had a love-hate relationship with these sleds. They can be very good once the issues are dealt with. The chassis is great, the engine had some issues.
My 05 900 RMK 159" track has over 9000 miles on it now, and it will soon be over 10,000 miles. It is on the second crank, which was changed by Polaris under warranty at 3300 miles, they updated the Pistons at this time, the engine has not been apart since.
The sled as released had several issues, (which are detailed in the appropriate 900 Forum section), but once you have dealt with these gremlins, you can enjoy a great sled at a bargain price, but be forewarned, unless you are mechanically inclined and have the resources and time to do your own work, it could be an uphill struggle, as the Dealers are of very little use, ..in fairness they never had the "time to get properly acquainted" with the 900.
Hope this helps with your decision. Cheers

Oops..., I forgot to add that my 900 flat out rips, I use it hard every day, it climbs well, boondocks great and it's a tractor when it comes to pulling out other wounded sleds..., ..the reason I still ride it; ..I haven't seen anything significantly better, in stock trim, from any of the OEMs as yet. However, my next sled will be a boosted four stroker...!!
