Torque peak doesn't = HP peak but, it should be close.

 

34 hp i dont think so isnt that what a 400ex has? Either way do these four mods and unchoke this thing and its going to screw........ muff, throttle stop, airbox cover and jets. that would bring the numbers up to about 44.

 

true the 450 is not going to be a tq motor its going to be all top end....dont they have like a 11k redline?

 

400ex has about 27 stock.

 

I'd say about 34 or 35hp, Idon't think it will be over 40hp but hey if it is man what a bike. Maybe then it will justify it's high price.

 

Well, considering that they Yamaha engineers were boasting that the four Pro motocrossers that they had testing the quad were clearing all the jumps that they cleared on their YZs... I'd have to say a low number would be 40hp. It should have a great power-to-weight ratio, so peak HP may not be that important as long as it has a nice flat torque curve.

I wouldn't worry about it guys, this thing should rip [img]i/expressions/face-icon-small-happy.gif[/img]

 

I was thinking about how I said it needed to justify it's price but if the power is anything like everybody thinks along with the low weight, which there is no replacement for. Plus all the other extras it has race ready suspension great handling and whatever else it has then it easily justifies it's cost. I hope it's a first and turns out to be a first year bullet-proof quad.

 

If it makes 40 hp at 10500, but only 15-20 at 6500 rpm, would that still be good?? I'd love to see a dyno on this..I bet it looks like quite the hill climb..Since a negative pregnancy today (thank God-I just had a boy 4.5 months ago), I might still be in the running for one of these. I guess one can always drop a tooth on the CS (I bet that'll be a popular mod)........

 

Pleasure4qt, Pepsi is better! Does anyone remember when Coke stopped making the original Coke? Why would they stop making something that is supposed to be good?

 

TyreSpinner,

Horsepower is absolutely important and is not just a number on paper. Torque may be what you actually can feel when you accelerate, but higher horsepower means you can sustain that torque higher into the engine RPMs. This means you can carry that same gear longer without having to shift to the next to keep accelerating. Shifting to the next higher gear decreases your final rear wheel torque but allows you to increase speed (which is the goal when you're accelerating). So if there are two identical machines but the second has more horsepower, the higher horsepower machine will win the race if the race spans multiple gears (assuming you have perfect traction and everything else).
