The 2010 Yamaha YZ450F first ride impression from Holeshot is here. We just wrapped up our first day of testing the new YZ450F at Leighton’s property and it's safe to say that Yamaha has reinvented the YZ with the 2010's innovative engine configuration, fuel injection system and completely new frame/chassis.

You already know what's new on the bike (if you need a reminder, click here for our 2010 Yamaha YZ450F Revealed story), but how does all that backwards-cylinder and under-seat fuel tank business work on the track? Let me tell you in one simple word: Awesome. After both Darryll and Damien came off the bike they were both grinning from ear to ear. The 2010 YZ450F is just “AWESOME”.

Taking weight off a bike, as well as a rider's back, arms and legs and making it disappear into the motorcycle below is no easy feat. But Yamaha has done all of that by centralizing the mass of rotating forces inside their cylinder head and dropping the fuel under the seat (a completely new frame doesn't hurt, I'm sure). The bike feels just as heavy and bulky as other 450-class machines in the pits-pushing it around and hoisting it up and onto a stand will give zero insight into the ride. Even when seated, the bulbous radiator shrouds, doubling as direct air intake scoops to the under-tank air box, give an air of heft and undeniable girth. But looks are deceiving. When in motion, the bike feels svelte, slim, nimble and light according to the guys. It's hard to describe but the 2009 Husaberg models are as close to a comparison as there is. This bike looses 40 percent of its mass when it starts rolling and feels like a really fast 250F.

Have Yamaha's cornered as well as their competition in the past? No, at least not for everyone. Some could coax them to commit to the ruts but in general they were reluctant to follow your instincts into and through a corner. That feeling or inconsistency is gone. The 2010 YZ450F has a light-as-air steering feel. This fits in quite well with the weight feel of the bike being non-existent at your feet and butt. Corner initiation is almost automatic as the bike falls off it's upright axis and into whatever lean angle you choose. It doesn't flop over; it reacts predictably and when you decide it's gone far enough, it stops leaning. It followed the bends around Leighton’s property beautifully. It was just as likeable in the air.

Well I wont bore you with words any longer take a listen to what both Darryll and Damien King say about this remarkably new YZF450 below.
