If you're set up right and all tweaked in, I'd say no problem with a 450 stocker. A nicely modded 450, On the other hand, will give anything a run for it's money. JMO.

I have video of my 440ex keeping up with a highly modded yfz450.

Its all in how its tuned.

[440ex. ehhh!!]

my 440 with stock cam was faster then this guys trx450r that i raced with.
but now, its a totally different story. :s i have 11 races (3 heats and a final for each) and 26 hours of hard riding on my 440 kit. plus what ever the previous owner had on it. and just from when i started racing i can feel a HUGE difference in power, its unreal, this guy on his stock kfx400 is right on my tail now. it sucks. but i guess thats wat happens when 95% of the time for flat track racing its pinned.
