If you race Vet and can afford it get a new 07 450, you won't regret it.

no 250F big bore kit will beat the massaive power and torque of the 450. at your weight go for a new 450 man, you will love it.

Go for the 450. If you have the cash the newer bikes are awesome. I weigh 210 and my older 426 just cranks out the power. The 07 Yama is going to be incredible. Buy Yama unless you want to be working on valves all the time. If you like doing valve adjustments a lot the Honda is in too.

don't even start with that valve bullshit.

Oh, it's only BS until you have to adjust them all of the time. Then it becomes reality. I have a friend who raced a YZ 250 F 2 seasons and didn't need to do one adjustment. Far from BS my friend.

GrayRacer, you got specs?
