What gives with the new 2006 WR450 weighing 5.1 lbs heavier than the 2005 and looks nearly the same and has the same specs???? I guess it must be the new 15.1 lb enduro computer that gets rid of the stock light weight 10.0 lb odometer! Cool, new, digital enduro computer offers speedometer, clock, tripmeter, etc. in basic mode – or pace management functions such as timer, distance-compensating tripmeter, average speed, etc. when switched to race mode. At least it has a steel frame the new YZ450 looks like a bear to rejet with the new frame coveing the carb access!
