I wanted to your guys opinion. I have an 06 450. I have the chance to get an 08 for 5000.It has been raced a couple times. The guy was a factory yamaha mech. Is it worth to sell mine and get the 08 or just keep mine and wait for 2010? My bike is perfect cond. I'm selling for 4000. If any one was wondering. I don't know if anyone has asked this before. If so, sorry for the repost. I'm new to this.
