The issue you are going to have is with the size of the tire vs the 250X power output , the heavier tire is going to kill a bit of power , if your willing to live with that then it should be fine , as I am pretty sure the 250 and 450 share the same swingarm , and they do share the same rim size (2.15x18) so it should have the space for the tire , so there should not be a clearance issue , more of a heavier tire vs HP output issue with a 110 as opposed to a 100 , along with the wider traction patch , which means more traction , but at the expense of power due to the larger/wider tire that is going to dig in deeper , and may bog the bike down some , at least in softer terrain like dry sand , etc. ....
