I was just reading an old issue of ATV action (august 04) the issue with the 450 shootout. Says the stock yfz put out 35.8hp and the 450r with 33.1hp. I was just wondering how accurate those numbers were. I was lead to believe they were more like 10hp more than those numbers. So what’s the deal?

 

well that was really before the quads was road tested i believe so i guess it was a estimate.

 

they did a dyno run on it. they also said the HRC kit added 10 more hp to the honda, same thing with the GYT-R yfz.

 

check out ctracing and they have dyno on the 450r and yfz while they are stock.

 

33.1[img]i/expressions/face-icon-small-shocked.gif[/img]. dont the 400s have that much?

 

Nah man, the 400's push about 27 ponnies, and the 450's are in the 32-37 range. Just an estimate.

 

just shows ya, dirtwheels is full of more $hit than useful information.

 

Oh that's for sure, but there bullsh!t is pretty interesting!

 

since these 450s only have power in the 30s how much do all these 660s (raptor) and 650s (ds) have?

 

Maybe you wont believe this, but the 450's are pushing a bit more ponnies than the big bores out there!
