I have a 2011 Kxf front end. The problem here is that in the Evo class the bike has to be an 89 model or earlier. However we raced for the first time last weekend and there was only 1 other bike that was an 89 model. Some supposedly Evo bikes were actually 2004 kx500s with the frames painted green. This is apparently acceptable but running 2010 forks in an 89 bike is not. 😁 it seems to me your allowed to cheat but only up to a certain level
