When I bought the 2011, I was hoping it would end up being the SX Championship bike this year, and it is! Congratulations to both Ryan V. and Kawasaki for making that happen. My last three bikes have been Championship bikes and all are still running, besides the 2011 KX450F, the 2000 KX250 which I still own(Ricky C.) and the 1987 CR250 (Ricky Johnson). As you can tell I go a long way in between bikes and I hope the 2011 KX450 will last me well into the future as well. P.S. The 1987 CR250 is still being ridden by my best friend and we both still marvel at how well it works both off-road and MX.
