Recently I rode all day with a 450. We are both AA riders. Keeping in mind all the negative press the 426 is getting - I smoked the 450 on a straight stretch of wet dirt road. The night before I rode, I re-sealed the stator on my 426. (yes it is street legal with a real license plate.) It laid on its side for about 8 hours. Rode in the back of my truck in 20-30 degree weather. Started first kick, with snow on the ground. I did not ride the 450. However, he could corner a touch better; when the power came on, the 426 could not be touched by the 450. Go riding in real life and you'll find that the magazine guys sometimes pimp the "new & improved." One final sidenote: An ISDE rider on a KTM 125 SX was a match for the Cr 450, even in a drag race. My 426 will not be sold off for a 450!!!
