What's this? The R6 makes more torque than the Big Green Bike below 7k? Interesting...



Beyond that all I really get out of it is a headache...

At first I was disapointed with the 749's peak power. Then I examined the curve and noticed how much more mid range power it has over its 600cc competition.

What good are desmodromic valves if you don't use the rpm? The Duc must be strangled.



The Honda is supposed to make max power at 12,500 rpm; here it's happening at 13,200. Allowing overrev to 15,000 makes more sense.



What's wrong with the Suzuki? It was much better last year.



I wonder how good these numbers are.

I wonder how the ZX-6RR will do with 36 less cubic centimeters?

Thanks VWW



This seems like a more useful report than the one the other day with aftermarket pipes. Doesn't really matter what the absolute numbers mean -- that is, how they equate with SAE horsepower etc -- what matters is how they compare to each other.



Really illustrates the fundamental difference between a twin and a 4. If you want torque and ride below 10000rpm, the Duc is impressive. If you wind the snot out of them, the 4s kick ass.



Cheers

Bob

My guess would be not that well. Definitely less torque, probably less peak power too, but at higher rpm.

There is definitely two schools of thought when it comes to making power. The Ducati has a nice wide spread of torque while the 600s are really peaky.



I'll take one of each please.

I'm not sure if you noticed, but 11,000 rpm is pretty damn high revving for a 750 twin. An SV650 redlines at 10,500, and it's a smaller engine. The limitation they're running into is (I think) piston speed, not valve float. One of the engineer types can comment on this in more detail, but a piston can only move up and down so fast before it somes apart

I don't think there's anything wrong with the suzuki. I think it's because the other bikes are so much better/stonger this year. The zuki needs an upgrade, that's all. I belive it's getting one for '04.

Now THIS dyno actually means something, unlike that Aussie dyno a few days ago. For the most part, it looks exactly like I expected.



The Kawi's steep jump in Torque and HP is at 7,500 RPM (others are later), but otherwise it's smoother than the rest. Yummy
