Anyone riding a 2006 WR450 yet? Are the improvements significant? I notice LA cyclesports wants about $700 more for the 2006, which I assume means they are still trying to move out the 2005s. I think the new computer with the speedo is worthwhile, becuase I'd like to dual sport the bike. Suggestions? Buy the 2006 or save the $700 and buy the 2005?
