2007 Bike specs?

Anybody find any juicy rumours about what factory is building what for next year? I Know we got another thread on the pros and cons of the new bikes for the riders and we know about Ducati and can guess about Honda but if you guys come accross any other stuff on engine configurations or 'not so secret' tests, post em here!

As soon as HRC pass on the technical data,and full spec of the new 800cc bullit to me, you will be the first to know !

.......s won't answer my emails

Heres some stuff from the mcn,a bit of feed back on the new Ducati gp7 800 motogp bike ?


I have to admit that the first lap with the GP7 was really exciting. I am used to testing new solutions on our bikes, but this was different to the others: it is a totally new machine, and so it's even more exciting than usual. It seems just like yesterday that we were testing the Desmosedici GP3 here at Mugello for the first time, but four years have gone by! Today we made another important step forward in the MotoGP project: it is as if our family has given birth to a second 'baby' and the first noises it has made are not bad at all!" said Guareschi.
"Today the new 800cc engine finally moved from the dyno to the track and we are quite satisfied with this debut. We started off by running a check on all the components of the new bike and over the next two days, if we don't encounter any particular problems, we will move on to phase two and begin the first set-up work," said Ducati Corse technical director Filippo Preziosi.
"Today is certainly very important, but it is just the start of a long path that we know lies ahead of us. A special thanks goes out to all the guys in Ducati Corse who have worked hard over the past few months to get the bike, with which we will race in next year's championship, out onto the track today, as well as all of our suppliers and technical sponsors, above all Shell Advance, who with their technology, experience and availability are making a decisive contribution to our project".

Does anyone know what configuration Ducati are using? I had heard Honda V3 in the past but in another thread Skid said he has heard of another V5 from them. I had heard a crazy rumor that Suzuki will go to a six cylinder but I find that highly unlikely. Past that, I haven't heard a thing from Yamaha or Kawasaki.

What sorta lump are they using in the Duke? They released any basic info or is it all just breif snapshots and how they "feel"?

The Suzuki 6 cyl rumour started because they might be using a 800cc version of the 1100cc stratosphere inline six. Its a very narrow engine, so that shouldnt be too much of a problem. But a V6 would be better for saving real estate. But with the new weight and fuel restrictions a 6 pot screamer is a step in the wrong direction. Honda have (once again) hit the nail on the head with thier (Still rumoured but now probably true) 3 cylinder. It will be lighter than the RCV, and it will use less fuel. Theres a good chance a 6 cylinder 800 will use more than a 4 cylinder 990.
To Suzuki`s credit, I can now see the logic in introducing air valves this year. If they can get it sorted and running at full potential by the end of th the season, theyll have a tried and tested system ready for thier 800, with a years experience to boot

not to sure on the spec for the Ducati,but the bike has been devloped and is being tested ?As for the Honda engine from all the sources i know,i will be the V3,but with Honda they could have V6 somewhere. ?very unpredictable,until you actually see it on the track !
Have a look at this,it does tell a little more ?
Ducati Test

The Ducati is a V4, Desmodromic valve management, tubular frame.

Honda will be either 3 or 4 cyl. Track debut on August in Japan with Okada.

Yamaha and Kawasaki haven't said a word, but I'd be surprised if they did something that is not an inline 4 cylinder.

King Kenny says he will use Honda power, though Honda haven't confirmed that yet.

i find it very difficult that suzuki will build an inline 6cyl engine for their gp bike. this sounds way to absurd to me

It`s just a ........ rumour. Probably came from England.

Thanks for that Teo, god I`d love to be able to speak Spanish and a subscription to Motociclismio

aah, so that`s my mission impossible sabotage target! I need more details. When? Where?

Typical. Yamaha have no imagination and Kawa just copy them.

You speak the truth. Yamaha develop an inline four MotoGP machine, Kawasaki develop an inline four MotoGP machine. Yamaha introduce a big bang firing order for their bike, Kawasaki introduce a big bang firing order for their bike. Kawasaki must have an inside man over at the tuning fork factory that Brivio and co. are unaware of.

The only Yamaha identity sign is the 5 valve per cyl design they use in their R1s and older superbikes. But I think they dumped it in the 2004 M1 for the more conventional 4 valve per cyl design (not 100% sure about this).

The Kawa is also quite conventional design, but going with rare designs sometimes end very badly (ie Aprilia RS3).

yea i think ur right teo i remember them scrapping the 5 valve per cyl thing.

They still use it in the R1, theoretically it's better than 4 valves, but it seems they haven't found a way to make it work in real life, the complexity of the camshafts blows away the little gain the 5th valve gives.

The guy who built the modern day M1, I forget his name Iwagawamoto Uchimichida or somthing, now works for Kawasaki. This dude was chief of M1 technical development for a few years, then for some reason he moved to Kawa. Maybe because technically he works for Yamaha and not Yamaha Racing Team, the thrill of winning or loyalty to the team didnt have a big effect on him and he just moved to a bigger paycheque. Anyway he took the big bang firing order and a few other Yamaha tricks with him. That`s the main reason Kawasaki copy Yamaha.

I think it`s old technology. Remember when they put it in the FZR1000 way back in `88? Turned it from just another 1000cc bike into the `busa of the 80`s. It was making power comparable to the GSXR1100. Back then that was saying somthing. It was a lot more powerful than other 1000s. Fast forward 18 years to the current R1. Even with the five valve system it`s not the most powerful 1000. I`m not sure of the exact statistics but I think the power rankings of the stock Jap 1000s at the momet goes somthing like Kawa, Suzi, Yamaha, Honda. Like I said I`m not sure. How much doues that new `blade put out? Anyway the point is its gone from a huge advantage to comparable if not worse than a 16 valve layout. I think theres just been so much RnD into the 16 valve layout, with the emergance of Superbikes and 600s, that Yamaha on thier own can`t develop the 20 valve layout as fast as Kawasaki, Honda and Suzuki combined are developing the 16 valve layout in their own bikes. They don`t use it in the M1, to my knowlege they`ve never used it in a smaller 600 engine, and I think it will be leaving the R1 in a few years too.

Yep the 2007 R1 is gonna be 4 valves per pot, confirmed. Teo's right, its about the cams and higher revs.

Ichiro Yoda.

according to mcn this week,kawasaki are on the brink of finishing their 800cc bike,and will start their testing immediatly after the Czech gp at Brno in August,should be interesting ?
