I have had an 01 and 02 YZ426. I have left dirk bikes for a while and am not up to date so I'm looking for advice. What year is arguably the best for the WR? And 400, 426 or 450? I want the lights, WR tranny and electric start would be nice too. I'm 6'3" and seem to remember reading that recently Yamaha shortened the height so I want to stay away from those years. Thanks in advance.
