How does the ST stack up?

Here are the stats for the ST1100, compared to the Magna VF750C, the Gold Wing 1100 Interstate, and the Harley Davidson FXD Dyna Super Glide.

	ST1100	VF750C	GL1100	FXD
Displacement	1100	750	1100	1574
Peak HP	100	84	64	61
Peak Torque	82	50	41	77
Dry Weight	634	505	718	666
Weight/Horsepower	6.3	6.0	11.2	10.9
Weight/Torque	7.7	10.1	17.5	8.6

I'm surprised to see how much more power the ST1100 has compared to the GL1100, with the same displacement and number of cylinders.

I'm aware that "not all displacement is created equal"; for example Harley's with their large displacement twin cylinders, don't compare in horsepower to a sport bike with half the displacement. But I'm still surprised that the V4, compared to the flat four, has such a disparity.

No wonder I love V4's.

I've added two metrics which I don't usually see discussed in the trade magazines, but which seem to me to offer a basis of comparison.

Weight divided by Horsepower, or what I call "Pounds per horse". How much weight does each of those horses have to carry. Seems like a way of leveling the horsepower playing field by factoring in the effect of weight.

Weight divided by Torque. This is similar to the "Pounds Per Horse" measurement, except this one blows my mind when I attempt to do dimensional analysis on it. If torque is measured in foot-pounds, and weight is measured in pounds, then pounds divided by foot-pounds equals what? The inverse of feet? 1/foot? I need to consult a physics textbook to figure this one out.
