P.S.
Your not going to find anything that is reliable for $1,000 now. It is Spring.

New Taoi, 50cc, still in breakin @170miles/285km. Today, ran it out-of-gas... took 0.95gals, but manual says 6L & dealer said 1.5 gals. When gauge hit E, I had another 50km. Running 92 octane, pure gas. Driving scooter hard, full throttle on hills up/down on ~40% of time. Based on 2 fills, 104mpg

I'm getting over 100 mpgUS at 50 mph with E10 gas in my Honda PCX150 including a couple miles on the highway at 65 mph.

I picked up a used Chinese 50cc 4 stroke scooter for $300 about three years ago. I use only in town as the top speed is about 30 mph. I usually run it wide open sometimes with a passenger and hills and still get right around 100 mpg. This scooter sold new on-line for only $800 shipping included.

For comparison of FE by displacement and rpm look at the mass rate of flow. That is how many cc per minute of air/fuel mixture is going through the engine. Compression ratio, air drag, and weight all affect FE. What you may want to ask is the total average annual cost per mile. This includes fuel cost, depreciation, and the value of your time spent on the road.
In Northern climates traction in snow and wind chill are key safety issues that need to be seriously addressed. Dual purpose tires, a full fairing, and a heater would be necessary on a motorcycle. An electric mountain bike with a Mullen fairing is the cheapest outlay but you need to value your time on the road. If you build your own Vetter style full fairing the drag will be cut in half so range or FE will increase by 50%.
Driving overtired is like driving drunk.

With >100,000 miles ridden on motorcycles, I can say 144 mpg is indeed possible with a 50 cc. scooter. My mid-60s Honda Cub got 145 mpg. I owned a series of two-stroke cycles which were gas guzzlers compared to the four-stroke Honda. My 90 cc 1970 Suzuki TS-90 averaged 75 mpg, my '66 Suzuki T20 (250 cc.) X-6 Hustler got 55 mpg, and my 500 cc T500 Titan got 30 mpg. My '77 Suzuki GS-1000 (four-stroke) got 50 mpg. All were ridden WFO with no clue about hypermiling.

Heated gear such my full set of jacket liner, glove liners, pants liners, and foot beds from Venture Heat are indispensable to a two wheeled commuter depending on the length of your commute. Mine is almost one hour each way and there many mornings that start at 45F even in July. I rarely ever turn this gear up past 40% even late into the season at 30F. I am toasty warm. Power draw is minimal.

A nice full face helmet is also a must for cold weather. You must use a pin lock visor to eliminate fogging and I appreciate the tight seal all the way around my neck offered by a modular helmet like my Schuberth C3 or the Shoei Neotech.

Unfortunately, snow tires for motos are nearly nonexistent. I may try to find an automotive snow tire small enough to put on my PCX150 for winter use around town.

The PCX150 is expensive but it is far and away the most advanced high fuel economy two wheeler on the market that is almost super highway capable. I run mine for one exit at 65 mph ever day but I wouldn't want to ride it all the way home on the interstate at redline so I keep to the back highways at 55 mph and still break 100 mpgUS. Used PCX125's are starting to pop up in the $2,000 range.

I had regular 100MPG on my 63cc scooter, sometimes even 105MPG.
I think it's very possible, when the scooter is variator limited.
Meaning, if the engine is going at max legal speed (in many places that is 30-35MPH), while doing only 5 or 6k rpm. The engine can do more, but the RPM limitation allows it to run less hot, and more efficient, compared to a lower geared scooter, that will do the same speed at 7.5k rpm.

Also, a fuel injected 50cc running 35MPH at about 4-5k rpm could easily exceed 120MPG. 144MPG is a bit hard to attain, but possible, especially when getting rid of the Variator, and install a gearbox (usually tri or quad-speed gearbox).
Speeds above 40MPH tax the 50cc too much, and will make it run less efficient.
Also speeds above 40MPH bring more wind resistance.
