Bore to Stroke Ratio
Ducati's new panigale motor has a wild Bore Stroke ratio.
Bore to Stroke Ratio
500cc gp bikes 54x54 1:1
duc 1198 106x67.9 1.56:1
duc 1199 Panigale 112x60.8 1.84:1
Duc moto gp bike 86x42.56 2.02:1
Ferrari F1 v8 98x38.9 2.52:1
CBR250RR 1986-99 1.43:1
CBR900rr 1996-99 1.22:1
CBR600 2008-12 1.57:1
Ferrari's stroke is almost as short as the NR 500's was.

Re: Bore to Stroke Ratio
I like it!
heres a little more to add to the list to compare.
current 1000RR is 76×55.1 = 1.379 and peak power @ 12K RPM
1098S stroke 64.7mm peak power @ 9750 RPM
1198 stroke 67.9mm peak power @ 9750 RPM
with the 1199's longer stroke (67.9mm) it's making peak power @ 10.75K RPM
