PS: rumor is that there's no knock sensors around. This combined with a rather crude Alpha-N system + no ion sensing + narrow band L-sensors = Armageddon or what?

That jagged front beak could have yer eye out

Some really revealing photos in that link. Looks good to me -and probably encapsulates all the improvements I'd be looking for - over the existing machine:

Watercooling
Wet, multiplate clutch
More grunt

I just wish there was a more road-orientated option (17" road wheels which take a 120 front, 180 rear tyre.)

So-called precision cooling (a principle similar to that used in Formula 1) involves only those engine elements being cooled with coolant, which are particularly exposed to thermal stress. The engine still continues to use air cooling, thereby preserving the characteristic appearance of the opposed twin boxer engine. The two radiators are small and inconspicuously integrated.

Erm...triumph of marketing over engineering that one or what? I.e. this means that 1M other engines out there who work a bit "differently" (purely water cooled, that is) are "wrong"? (or not Formula-1 "compliant", he he).

Maybe you should ask the question why was the decision made to go with water cooling for the cylinder heads?

my understanding was that water cooling allows tighter tolerances, which allows more power and less emissions?

Also reduces the noise from combustion.

Didn't I hear that this is a Porsche designed engine?
not sure if thats a good thing or a bad thing really!

Didn't they also do the Vrod motor too?

Yep and the early SEAT Ibiza's

I thought the Porsche design element of the early Seats was limited to chassis/ suspension?

Steve

It was emblazoned onto the cam covers, I worked for SEAT for a year once and they used to make a big thing of the Porsche design

Aha, a little more reading shows that to be closer to the truth, it seems Seat and Fiat were going through a difficult divorce, and arguing over who designed what and who owned what name etc, so strategic partnerships were started which is where porsche comes in, very little in design at all, more like a marketing strategy which led to VAG buying the brand,

So we were both right......or both wrong..

They did Steve - HD's Powertrain Engineering team designed and built the original VR1000 motor for the race bike, Porsce stepped in to assist with the motor's design programme and carried on with an active role when the V-Rod was under development.

Got to admit, the Revolution motor in the VRSCR I onced owned goes down as one of the nicest engines I've owned. Really smooth, powerful (yes really - it went like the clappers!) and sounded fabulous. Very thirsty though.

I would have loved to see that engine in a Buell chassis
