I am looking at getting a KTM but not sure on which one to get. I recently rode the 525 and loved it, but what i want to know is how much of a difference is there between the 450 and the 525, How much of a noticable power difference is there between the two. I have been looking at the KTM website and the only difference I could find is the motor size. which one would be better for my kind of riding. I like to ride fast and push the limits of woods riding on trails, and at the dunes.
