How much of the top end are you talking about. Now I dont know for sure but from what I've read is that the port timing, and pistons are different. The other thing would be the fact that 2010 has four injectors and the 2011 has two. The bottom end is the same as far as I know so it should bolt on with no problems. You should be able to search parts from the two on Official Global Website For Polaris ATVs, RANGER Vehicles, Snowmobiles, & Victory Motorcycles

I think you should look closer. The pistons are different and the Cylinders are as well. This transformation will fit but It still does not fix the four injection system on the 2010 which is the biggest down fall. The injectors switched between low and high throttle position and it is that switch that it failed.
