Two Polaris Factory seat options on the 2012 snowchecks...There were no seat options on the 2011's
1) Normal PRO RMK
2) PRO Switchback (shorter/wider)
Aftermarket seats avail are
1) Skinz Protective Gear Airframe seats. With some different choices on height and color. Custom order. Give yourself at least 3 month lead time for custom orders on this. (a bit lighter than stock)
2) WRP modified factory seat in +3 and -1.5" sizes (a bit heavier than stock)
3) Boss seat, wider and taller than stock. (a bit lighter than stock)
4) Mountain Mod Seats, Higher/wider than stock about the same weight as stock)
5) R&M Lightning seat (more storage space, wider and taller than stock, about the same weight as stock)
I don't believe that the Rush seat will work on the PRO RMK.
The fuel tanks are much different under the seat. Curts FTX Custom pro STARTED as a Rush and used the much different rush fuel tank and a custom tig welded tubular seat support frame to replace the seat support that is integral to the rear suspension upper carriage. The seat itself needs a "cradle" to support it... it cannot simply "bridge the gap"
The seats must fit exactly onto the tank... the tank is part of the support for the seat...And I don't believe that the front of the Rush seat is the correct shape.
IMO... The seat is a function of what kind of riding you do. If you sit more than stand or stand more than sit... If you are athletic in your riding jumping from side to side on the sled or stay centered more and shift your weight. The seat can be a place of comfort or something to sit on when you are eating lunch. IMO, for athletic riding, the seat should get in the way as little as possible. If you are a taller rider with longer legs, the stocker gets in the way less than if you are a shorter rider. The wider seats can also affect how the running boards feel. I'm shorter, the running boards feel narrower because my legs have to be spread more than a taller rider on the same seat.
