Default How much horsepower in 450?

Hey everyone I just bought a Raptor 700 but had my eye on the 450. Didnt know if it would be good for me. After reading about them it seems like they are very fast but i figured the Raptor would be faster? The Raptor has a HUGE CC advantage so I would think it would blow away the yfz450. Is this true or are they close in performance? How much HP do both make about?

Dont get caught up on "which one is faster", thats just silly. Both of them can go faster than you'll ever get up to on the average day in the trails. The real question is what kind of riding do you do? If you're a racer and ride MX tracks predominately, then the YFZ450 would have been the better choice. If you prefer trails and more "leisurely" riding, the Raptor is the better choice. If you ride dunes, theyre both pretty equal.

The Raptor has more cc's but the YFZ winds out a lot more, which is where it produces its power. As far as power and speed, they are pretty much equal right out of the box. If you just bought the Raptor 700 then dont worry, you made a good choice no matter what kind of riding you do. The Raptors require less maintenance as well, the YFZs generally need to be rebuilt more often, so thats something else to consider. All in all, theyre both just as good.

I'm guessing you are talking about a drag race. Some ppl will tell you the rappy, and some will say the YFZ. To tell you the truth from what I've SEEN, it's a driver's race. They are both close enough to let the best driver win. They are two different animals though. Yes, the rappy is a torque monster that'll get your butt moving quick with a zap of the throttle. The yfz is a high strung engine for a 4 stroke that sort of reminds me of a piped banshee. They don't have near what the rappy does down in the low rpm's, but once you get halfway through, they start to scream, and then you get that mad rush to the higher rpms and you better hold on. They are harder to drive to their max potential though. It's a very FUN powerband though, but then again, I LOVE violent explosive powerbands better than tractable power. They both get you there at the same time, but it just puts a bigger smile on my face. Overall I think a 700 would be better though for all kinds of riding.

Thanks for the info. I sort of raced a yfz this weekend out in the pit. we only got to about 4th gear opened up but it was a good race. He got me off the start because I suck at launching but I caught right up near the end. I hope to race him again this weekend after some practice! :)

ive ridden both, as im sure many people around here have, and they are very very close... the raptor has alot more torque and maybe a few more mph on topend. the 450 handles a little better, they are close to the same specs, but it just "feels" lower i guess, that is really the only differences.
