Is that for stock? I doubt it. I was able to get just over 47hp on an '04 WR450 that had all the free mods on it with a stock pipe and Pro Moto Billet insert. I'd say stock was closer to 41-42.

Dirt Bike magazine did a dyno last year of an 05 WR450. Came in at 45 stock. Have never seen a 250 but the YZFs come in around 35 stock.

WR250F bone stock no mods is ~27hp. Free mods and slip-on muffler get you ~35hp.
