Racer X Tested: 2013 CRF250R


The 2013 CRF250 is about as close as you can get to being the perfect 250F. It does everything right and leaves most riders shrugging their shoulders when asked how to improve upon it. The main focus when you are trying to make any 250 better is making more horsepower and then customizing it to your own preferences. We turned to some experienced companies to help us turn our perfectly capable Honda into a fire-breathing race machine.
