Britalican well since the gearing wouldn't allow 100mph, i would have to guess kph or yards. I doubt he has altered the gearing to allow 100mph, or he would be getting smoked in every race.

JBGILL06 100 what? MPH, KPH, yards?

I would think there only in the 70s somewhere stock.

Not to get off topic but anyone see the new YZ450F, they turned the top end around or something like that so that the exhaust dont come out the front, it goes straight back where the intake would usually be.

Yamaha seems to be on the right track, gotta say that about them.

traitor08 Not a fan of the kfx. Seen one blown up 3 times, all new built motors with less than 20 hrs. The racer who had it said it made him nervous t race because it chucked the rod through the case while going up the face of a 60ft tabletop. Since been sold and he has 2 450R's, ones a 520 or something and the other is a built 450. The 520 puts out 54hp.

xx700xx Anyways, I think its incredible how fast the 450's are! I wonder if Honda did a DOHC motor like in the 450's what kinda beast it would make the xx. I really dont know much about the engineering behind why Honda went with the head they did but I wonder what kind of monster it would be with a 5 valve dual cam head? Also saying dont race a 450 on the track is funny to me, the xx was never made to hit the track just like the 450's really aren't made for trails. I proved that last weekend. A 450 will blow me away on the track with the right rider and I'll blow the 450 away in the trails. The xx is simply the comfort king on abused trails. It takes a lot out of me to make it happen on the track. I did race a yfz450 on a small track at rocky glen, the guy couldn't lose me and i would say we had close to equal riding abilities.
