Aerohead
I suspect those are 1000cc sport bikes with close to 200hp, the modern version of my CBR600 get 125bhp and without some aero improvements would be hard pressed to go much past 160mph. they also have a Cd in the nabourhood of 0.7 or more. and in the crouched riding position would have a Frontal area around 6 sq ft.
In my youth I would consider that 186 mph as high performance, now a days unless it can also get close to 100 mpg at 70 mph on the interstate it just doesn't cut it.
