The difference in peak HP is not going to be as big as the difference in torque across the RPM range. Don't have any numbers for you though. :thumbsup:

I have a 450 and rode a friends 250 at Lake Elsinore vet track. I was taking it easy on his bike, but it definitely required more advanced planning if you needed speed for a jump. It is not quite as heavy, but seriously behind on power/torque. It was a little easier to throw around though.

I fell in love with the 250f at Elsinore. I rode both a 450 and a 250 and actually rode alot faster on the 250 out there. I am surprised you had trouble with it.
