Indicated 70 mph ~5200
Indicated 80 mph ~6000
Indicated 55 mph it would depend on which gear you are in. I don't know.
That doesn't tell you much though. It doesn't say how the motor feels at that rpm. 6000 rpm is a lot for some motors, heck it is redline on a lot of motors. On the Wee, that is the sweetest range 5000-6500 for highway riding. The motor feels really good at that rpm on the highway.
The Wee will do an indicated 80-something mph all day long 2 up with the motor spinning ~6000-6500 rpm maybe a bit more. No problems. Not much power in reserve at that point, but no problems and the motor feels good.
I am impressed with one thing about the Wee's motor and highway performance. I once rented a stunningly beautiful '99 Harley Road King. It was almost a new bike, 6000 miles and less than a year old. I distinctly remember that thing feeling out of breath at 80 mph. It felt like it didn't want to go faster if it didn't have to. I can see why so many owners modify that motor.
The Wee on the other hand feels great at 80 mph. It doesn't feel out of breath. It is a different sensation entirely. What slows the Wee down is wind resistance as you near 90 mph. Clearly the Wee needs lots of time to chew on the wind resistance that you get at 90 mph to accelerate any more. It has motor/gearing enough to go well over 100 mph but it is gonna take some time to get there. The Harley felt really pushed over 80 mph, not with fighting wind resistance but the motor's vibs felt like protests. The motor felt overdriven, very strong and unpleasant vibes compared to below 80 mph.
The Wee has amazingly long legs for 650cc's.
