It is all clear to me now. Fascinating. I must research the difference in torgue and bhp specs between Ducati 1098r and Hayabusa.

I said I wouldn't do it, but here goes. While I don't have the numbers for the new Hayabusa, they should be similar to the Kawi Ninja ZX-14. Per Motorcyclist Magazine, the published peak rear wheel numbers for the ZX-14 (Feb 08) and Duc 1098 (Jan 07) were-
ZX-14 167.2 HP 105.2 Ft. Lbs.
1098 144.3 HP 90.9 Ft. Lbs.
Then again, when Motorcyclist previewed the new Busa (Aug '07), they stated "considering the fact that the ZX-14 makes a buck seventy-five at the rear wheel....one can assume the 'Busa will make at least that, and likely more." What happened to those extra eight ponies is anybodies guess.

Both the ZX14 and the new Busa seem to have in excess of 190 BHP on tap..........

They may, but that link doesn't really work for me, at least to prove your point. The Motorcyclist numbers are for bone stock bikes. Are we talking apples and oranges here?

The ultimate machine, as far as I'm concerned, is one that has the proper balance of torque/hp for what it will be used for. Also, someone mentioned NHRA earlier. Just for the record, the Harley V-Twins consistently out perform any other engine designs in 1/4 mile racing. In fact, the NHRA has made Harley racers add weight to their bikes, so other manufactures are more competitive.

I was searching last night for an article I had read on this very fact I almost couldn't believe that I had actually read here. What Harley rider hadnt learned that lesson in a quarter-mile

I was hoping he was referring to bone stock ones, tho even stock they will get sportbikes out of the hole. But the V-Twin wasnt designed to do 180mph, so of course it doesnt get our bikes on the top end.

This is the best example I have seen

and I will have to agree with you overall perspective V twins are sprinter and not long-distanc haulers but I can remember seeing some old articles about the V 4 sending the in-line 4 the way of the dinosaur and It could have possibly happened if it hadn't been for soft metal minor design flaw and bad publicity and before anyone starts I'm speaking of the V 65 series

It still seems to me that both the ZX14 and the 'Busa are really understressed - almost lazy if you like, when you consider that they're getting over 200 BHP from a litre class superbike which you can buy for the street. I have a video of a turbo'd 'Busa which delivers 499 BHP - now that's stressed !
But why are discussing non- CBR units here ?
Someone's lost the plot.............

This topic is like hell in that it is eternally hot.

I tend to agree with Honda_Hurricane: "Torque is measured; Power is calculated", but I'm writing to ask a question:

Pacojoseph, that dyno chart showing ninja zx14 seems to mix up torque and horsepower, the colors i mean. doesn't it?

Shadow it seems to me that we have moved into the broader spectrum on BHP now, if you can't handle the copilot seat get the hell out the way
And Bob you're right, there seems to be something wrong with Paco's example

You've got that right. Don't blame me, I scanned it straight from the mag. They make a lot of mistakes, many of which I catch (not that one though). I've always thought about applying for a job with them as a proofreader. Whoever does it now ain't worth a sh*t.

I had a V65 Sabre up until a couple of years ago. The rap against them was that they had a problem with getting oil to the rear cylinder cams, causing premature cam wear. There were several aftermarket fixes produced which were expensive and involved drilling holes in the head, so I passed on them. I did read an article, an alternate take on the oiling mods, written by a guy claiming to have been a road tester for the V65 before it was released and who stated that he and his mates never saw any of the problems others reported later. The one thing I took from it was to always keep the revs down untill the bike fully warmed up, and the last time I pulled the rear valve cover off my V65, the cams were in pristine condition.
