no?

No
try this. get your torque wrench out and holding it on the end turn it to 65ft lbs. Now do the same holding half way along the handle. That is how the engine feels  IE to travel at the same speed you will need a wider throttle/more pressure. This is because the leverage is less advantageous to the engine, just like holding the torque wrench handle closer to the pivot point.
For any given speed it is a balance of the pressure in the cylinder(s) versus the leverage and the resistance.
at the same speed the resistance is the same. so you are down to balancing the cylinder pressure against the leverage.
Regarding cruising speeds, often I hear here that people want a bike that will cruise all day at 100 mph.
There is no such bike.
not even half a day.
probably not even six hours.
Most bikes struggle to run for much over three hours before needing to stop at a garage.
I like to use the smaller roads, here in France the speed limit for any non dual carriageway is 56 Mph. This is precisely where the Enfield is happiest. Dual carriageway speed limit is 65 Mph which the Enfield can just manage without any drama. Only on the peages (motorways) which I try to avoid can I legally ride faster than my bike is happy. I think this is close to the situation in most of Europe with a few minor differences.
My bike can manage to run for nearly eight hours before needing to stop at a garage. Which means the bike is capable at covering 400 miles legally in the same time a Hyabusa could only cover 382 legally (due to fuel stops).  Sadly I could never prove this because I would need to stop before the 400 miles were up
