HI EVERY ONE IM NEW SO MERRY CHRISTMAS TO YOU ALL, DOES ANY ONE KNOW WHICH WIRES TO SNIP ON THE WR450F TO GIVE IT MORE POKE AT LOW DOWN REVS AND ELIMINATE THE REV LIMITER, THANKS REGARDS PAUL

how fast dose it go anyways?

I don't believe they are electronically restricted so don't go chopping wires. The only restrictor I'm aware of is a plastic throttle restrictor which limits the amount of throttle movement there is. Take out the throttle slider and remove this to gain full throttle action and you should be alright.
