Greetings all, we just got done ripping around Budds Creek Motocross Park in Maryland on the 2010 Yamaha YZ450F. And yes, Yamaha’s new 450 dirt bike is the real deal. The two things that stand out the most in my mind is just how much stronger its bottom-end and mid-range engine performance as compared to the 2009 Yamaha YZ450F. Also of note is the way in which it handles. Most specifically during initial turn-in. Check out the attached video and see what it is like. Look for our full review early next week.
