I buy it. Since superbikes begin life, technically, as road machines, they start out life with a motor that is tuned for street usage. Given that an engine such as one would find in a MotoGP bike, with a stratospheric redline and powerband, would not be ideal for street usage, it makes sense that you'd have more torque in one of the superbikes than the 200cc smaller, race-focused GP bikes.
