Were you just rolling the throttle on under 4500 rpm or are our motors actually that weak below that point?

Just wanted to come brag about my '04 450. I was at a bike rally this weekend and entered the dyno shoot out in the 0-550cc class. My WR won. Its pretty much stock with free mods and it pulled a 48.8 HP run! I think it was awesome. Not to mention i had my motard wheels on and was schooling 'busas all day in the corners lol
That's awesome! I also have a 2004 WR450F and just love it. Incredible bike!

Had my WR450F 05 on the dyno at Yamaha and they got 43.6 HP
After a hour of tuning and re jetting they got it up to 48.7HP
I noticed for your dyno chart that your bike made it max HP at 8500rpm.
My one does it at 7000rpm..
Anyone now why.. might be the grey wire, which I have not yet cut.
Cannot wait to give it a try...

I sold my '02 yz426f over a year ago. I bought a new '06 WR450F last month. I'm not sure what the H.P. is for a 426. I believe it's around 38 to 42. If it's not, I'm sure someone will correct me in here, which is okay with me.
Thumper426, are you saying you can get the same 48.8 H.P output on a WR 426? I would love to see those kind of numbers out of mine.
I tried to change my log in name here, but for some reason it won't let me so I can have a 450 instead of 426 now.
