I found a local 07 YZ450 in mint condition for $3000 and I'm really tempted to buy it. I know I said I'd never sell my 426, but the shiny aluminum on the 450 is distracting me. Let me ask a simple question: Why should I not sell my 426 and get a YZ450 instead? Another thing I'm thinking about is the green sticker. I may be moving back to CA within the next couple of months, and the green sticker for the 426 is a plus. I don't want to be limited to MX tracks in Southern California for part of the year.
