When I got my Banshee the title said 49 hp. My friend had one with Toomey's, 2 into 1 air filter(no airbox), and mild porting( 3 - 4 hp), and the carbs set up right and his pulled 64 on the Dyno where he worked. They should be close to 60 with a fresh motor, pipes, opened up intake and the right jetting. The 2004/05 TRX450R's were supposed to have 33 and compared to my old stock Banshee, since you all say they are more like 35hp stock, I'd said the 450R didn't have but 20. My WR450 is supposed to have 47 the way I have it and isn't not even close to the power my Banshee had modded. Stock it was about the same as the WR is now. 49 might be a little high but not much. 2 or 3 hp maybe.
