yeah agreed, its all about the torque figures... hence why my 996cc Ducati eats Jap bikes in the bends but is sometimes caught in the straights...
Or my 1100cc Moto Guzzi takes 1580cc Harleys to task like they're standing still!
I would say any engine with a greater number of cylinders but with the same cubic capacity would lay down power better... at least be more free revving...
