Bridgestone - The Ducati is faster with Checa onboard over a full lap because he is faster round the corners than the other riders. It has less power and less straightline speed than the fours.

A twin will produce less power than a four of the same capacity. The reason that a figure of 1200cc was chosen with 1000cc for 4 cylinder bikes is that a 1200 is slower revving and weeps the same volume at 12,000 revs as a 1000 4 at 14,400 revs (do the math).

2cilinder has so much more torque and the ducati with desmodromic valve's can rev higher then that and you know how much the gsxr revs? up to 14.000 and its over.
you know high the duc revs? no? i know 13.500 revs!
did you know that the KTM 1190 RC8R punished their engine at 14.000 rpm befor in production? no? you should read more...thats with spring valves. you know what desmodromic means.....! right?!

2007 ducati gp7 makes 19.000 rpm sinds that Yamaha and honda have Pneumatic valves. honda even later. to make up the rev.
does desmo helps SURE

while we are on about different configurations of engines and fairness, what would have been fair for say Honda/Aprilia 500cc 2 stroke 2 cyl, Roberts 500cc 2 stroke 3cyl, and any manufactures that i may have forgot, during the days of 500GP? not been of an academic or engineering back ground, i can't understand why it's relevant now and not then?

The GP7 is a V4, big difference. There is a reason Ducati doesnt run a twin in GP, it would get destroyed.

Why don't you explainb to all the boys and girls that while revving to 13.5K the Ducati still doesn't produce the same HP as an I4 reving to the same peak.

Since his first day in GP500, the guy was crumbling like a wet firecracker every time he met his own shadow...

Sure they found the solution: No more pressure, he's walking every race by a country mile,

Not too shabby for a privateer bike !
