Chimmer, your right, but I can' tfind the rpm's. I think if I remember right its 500 less than th yzf450 (bike)

 

Here is my take on comparing the two quads. I put in about 20 hours of ride time on my YZF at St. Anthony's last weekend and I came away very impressed. The motor is unbeleiveably strong for stock. It's strong everywhere and would pull my '01 Raptor no problem. There is no comparison when it comes to suspension or turning. (This is what I like most about the quad.) The YZF shines in these areas as well when compared to the Raptor. It works great in the dunes when ridden hard.
I drag raced my wifes Z which has a full LRD pipe, Hotcams, and K&N and it was no contest. Straight line speed isn't everything, I just wanted to compare the two. I also drag raced a piped Raptor and my brothers Cannondale with the same results. It fits my needs great and I wouldn't consider another machine at this time. Just my 2 pennies.

 

I'll confirm all of Buddahs straight line comparisons as soon as I get 10 to 20 hours on mine. I am extremely expressed at this point and I've only got all of an hour on it.

The 1st gear is tall as others have mentioned however this should be an aid on quick starts..almost like starting in 2nd on some mxers.

How do all you guys pass the first 10 to 20 hours off without going WOT?
