RacerX's online 450 review/shootout picked the KX450F as the No.1 450 MXer for 2006. The YZ450F was second. No one I know has even seen the YZ yet, but I told you that the Kawi was bad to the bone! One racer we know picked his up one morning and successfully raced it at an AX that evening. They are that good out of the crate! Super motor! I sure hope our YZ is that fast. The boy wanted to stay true blue.. er, yellow, though.
