Just wondering if I was to build a bumper lift for the front wheel of my 250cc (YY250T-2 or MC-13-250) touring scooter weight close to 400#. And if it was to break down how far could it be pull (if Possible) by the back wheel or would the engine be cranking due to the drive belt at a speed of 50mph or less

Just based on having cars towed, I know they always lifted the wheels that drive the car. So rear-wheel drive, they'd lift the rear wheels.
Going by that, I would think you'd need to tow a scooter lifting the back wheel off the ground. But read my official title over there under my name and understand that I am NOT an expert here!

The CLUTCH ASSEMBLY consists of the PULLEY and the CLUTCH as one part. In order for the clutch pads to be thrown out, the PULLEY has to be turning fast enough creating enough centrifugal force to have the clutch pads thrown out WHICH IN TURN GRABS the bell WHICH then turns your wheel.
And what turns the CLUTCH PULLEY in order for the CLUTCH PADS to be thrown out to grab the bell, the Belt which is Driven by the Variator which is attached to the Crank and is only turned when the motor is running.
So you can put you scoot on the center stand with the wheel off the ground and spin the tire as fast as you want the only thing that will be turning is the BELL BUT NOT THE CLUTCH ASSEMBLY.

Yes you can but you will be putting stress on the front forks and steering head that they were not designed for and forcing the geometry to out of where its supposed to be (bike naturally wants to lean into a turn due to the angle of the tree and steering head). Also you will be loading (mildly albeit) the back of the gears constantly as the rear wheel will be turning the gear reduction unit the whole time which at highway speeds could generate quite a bit of heat.

My thought as a welder would be to build a small trailer that consists of a center U .channel that the wheels sit in and a axle , , you are not going far or fast so it does not need to be that heavy , if you ride with other riders you could build it as a group to spread the cost to next to nothing with everybody having it's use if they break down . And you having a 250, put a hitch on it and you could be the rescuebike , nothing looks better than a bike pulling another bike on a trailer

I use one of those U channel rigs that plug into the hitch receiver and hang off across the the back of a pick-up truck. Pretty much like what is used for dirt bikes. Easy and safe to load by ones self since it is not being loaded into the bed of the truck. So it is lower and easier to manage alone. It can safely and securely carry a 375# Honda Reflex scooter. I added trailer lights to the channel since the bike partially covers the truck lights.
There are gadgets that allow you to tow a bike by securing the front wheel. A bike can safely be towed this way but it would be best to limit transport speed to about the max speed of the bike. No harm should come to the transmission turning at that speed. AND! the engine would not be running so the transmission would run cooler besides.
The front end of the bike would/should not be raised too high and should be fine. Kind of like riding an extended wheelie, except the rear wheel does not carry the full weight of the bike, but rather is shared with the front too.

From the manufacture of the caddy type tow devices:
"May not be suitable for towing drive shaft motorcycles, most scooters and other bikes like the Yamaha TW200. Be sure to check with your dealer and read your owner's manual to be sure your bike will not be damaged towing in neutral.
The Caddy is NOT for use on a Motorhome, Camptrailer, 5th Wheel, Bus or other LONG vehicle.
The turning radius will lay the bike over and cause DAMAGE to the bike!"
So in tight turns the steering head angle would cause the bike to lean which is a know issue with this type of unit which the maker admits to expecially if used with a long vehicle. Not really intended for bikes with a final gear reduction drive like a shaft drive or a scooter either.
Note that the units available for sale cost three or four times what a hitch rack carrier does and twice what you'd pay for a Harbor Freight trailer.
