Apart from the cost ..I doubt the 2009 R1 being more advanced than the 2009 new Ducati 1198. Traction control, less weight (171kg), more power, dry clutch, etc...all these features on the bike are directly carried from thier racing paddock. And not to doubt the desmodromic valve system which is successfull than any other valve system yet on high performance motorcycles.
but as far as looks and personal choice is concerned..i still stick to being a Yamaha guy

If anything, the new RSV will kill the competition, not so much the new R1 or the Gixxer. Owing to its weight alone.

Aside from something very strange like pasta sauce in the ECU of the RSV, this will happen.

Let's wait and watch. Couple of months down we'll have a clearer picture.

Buddy of mine sent me the dyno chart for the new R1. Doesn't look so good. Torque curves are all over the place. Thought I'd share this with you guys.

Peak rear wheel h.p on the stock seems around 170.

very strange . if anything i would have expected a smooth curve with the fancy new technology . as far as the jap bikes v/s duc. cant compare the 2 . with the duc you are getting an extremly powerful twin that is very rideable around town, a great chasis and nice suspension . but if you spent a bit on say the 08 blade. in terms of getting ohlins suspension it would most likely crap all over the duc around the track . but then again the duc is most likely the hottest bike around at the moment/.

Sorry if my knowledge is low ... but I think I saw that Ducati Desmodici is V4, not V5 ... Has it been updated in the mean time?

The only "On-Road V5" I have heard about is that VFR Rumour of going V5, which didn't happen?!

I am talking about that Ducati Desmosedici that Ducati made in limited numbers.It was a rip off their 1000cc motogp bike-single seater,multipoint micro fuel-injected,200+hp.It was the only roadgoing motogp bike.Since all it had a motogp engine I thought it also a V5.This bike was inaugurated by Loris Capirossi in his last season at Ducati......................I wonder how everyone forgot it !!!!!!!!!!!!!!!

The Bike was called Desmosedici RR.

170 PS at the rear wheel is about 5 PS more than the '08 right..?
That's pretty decent if one considers the new crank i guess. Slightly more power coupled with supposedly better usabilty seems like a good bet.
Like you said.. Only time will tell
But the figures you've posted don't seem promising
The R1 seems to be as peaky as ever....

Well no one actually forgot about the Duke RR man
A bike like that comes along once in a VERY long time..

But paying as much as you would for a Ferrari makes the RR a dream bike only. An R1 or a Blade would cost half as much as the 1098 does, let alone the RR
And the multipoint micro fuel injected part seems more like a filmi punchline than a feature from the specsheet

The RSV however is priced competetively and on paper seems to blow the socks off all the Japs..
We is waiting for her

Ross, what's the source of the graph? AFAIK it's not been released to the general public so how did Akra make an exhaust and how did your friend get hold of it to get it on the dyno?

Are you sure it is correct Curve? The "Akrapovic complete exhaust" curve is below the "stock exhaust" curve, in some rpms ... I think it should provide a complete positive gain ...
Secondly, the max rpm comes at 10krpm, NOT 9.1 krpm as this curve suggests ... Anyways, maybe my lack of knowledge..


btw Quite a strange curve, torque decreases 2 times before finally decreasing after 10krpm.

It goes contradictory against what Yamaha ofiicials boasted, that "inertial torque" stuff! They said entire curve will be lifted upside after 7 krpm especially ...?

I got it from him couple of days ago, and posted it here only after verifying the source.

In any case, I hear it's been put up on Akrapovic's website as well, although I did look and did not find it.

Akrapovic, Graves, and Yoshi have had the 09 R1 with them for sometime now to develop the exhausts. It's a known fact from quite sometime.

The figures don't seem promising, and confirms what I felt that the torque seemed down a bit.

More than the power, what we actually need and feel is the torque. What we feel through the bars is usually mistaken for the power

Look again. The Akrapovic complete exhaust curve and the slip on curve is above the stock exhaust, at least where ever it is meant to be.

-@Maverick46 ...And the multipoint micro fuel injected part seems more like a filmi punchline than a feature from the specsheet

Here is that filmi punchline or what I made out of it:
Ducati.com

See the TECH SPEC - fifth line....................it wud seem more filmi than what I said.!!!!!!!!!
