Yes.

No surprise at all, it was being discussed openly by the DD Race Committee (well the Chris Bushell/John Montgomery part of it) with Tim Macabee at the NEC last November so must have been "known about" before then

Yes but, why would you? The 800ss is eligible now and has more potential. As does the 800M. Mind you, what now the 800M? The gap between the 695 and 800 is narrow enough for the 800 to be axed.

Agreed, the 800 surely must make more torque and have more potential for a monster midrange?

Mmmmmm ...

God, wouldn't you love to race an 800 in minitwins!

I shall have my PC in my grubby hands next week and shortly after some Ti race cans. They're going on the new 800 whilst the other one is undergoing some surgery. Dyno runs in a week or two - I shall post the charts up here. Did you know that the latest PC's allow you to add some extra tweaks that simulate the accelerator pumps on flatsides? That should be interesting for instantaneous response exiting corners.

As for torque - mine's making well over 50lb-ft now. I promise you a go when it's all sorted m8.

Are there any technical details of this 695? It sounds like they've probably done the same thing with the 695 as they did with the 800. Longer stroke, more valve lift and shorter duration. That seems to work well with the 2vlv motors - I think Moto-One does a good appraisal of the 800 summarising how they developed it.

Ooh, that sounds interesting. This thing sounds like it would be a real weapon in the class!!

I can't wait to have a go on it! At Cadwell please, I'll order the sun and plenty of it!! And a brand new set of supercorsa pro's. Mmmmm

not sure about the 800ss, but the s2r monster only makes an extra 4bhp and is heavier. than the 695

[twpd]

My 800ss is making 77bhp at 8200 with std pipes, filter and fuelling after a little tweak I found. More important was the midrange boost I got. I posted the chart up elsewhere in the SS forum. The S2R is less powerful than the 800M according to various sources. Whilst the 695 sounds good I doubt it will touch a well set up 800.

I've just added all the info to ducati-upnorth.com click here for more details. More HP and longer service intervals, woo hoo
