I was at my dealer today and he said that my bike (01 426 wr) is not made to race and that i should buy the 450 yzf. Setting the fact that they want to sell bikes, how much better is a yzf over a wr for mx. I have changed the seat and tank, removed the lights. At this point does my bike weigh close to the yzf plus the coil and extra gear? What can I do to help my wr more race friendly, besides all the free mods. Or should i risk a divorce and trade in for the 450?
