Other than the 600 RMK and the 136 Rush there aren't many changes. Mostly graphics. I wasn't expecting anything major considering what Polaris came out with this year. They just filled a couple of the holes in the lineup. Overall I think it was a good release.
I would of like to see the FST in the PRO chassis, everyone else is going four stroke and the FST really has not been a bad motor, just in the wrong chassis.
