i don;t own a bike yet, its just something i always wondered, as i always thought the heat came from the engine because of it moving

It really depends on the bike, as to what would happen. Alot of bikes have thermo fans, that will run cool air over the radiators, or cylinder, when it gets too hot, to stop it from seizing. I've seen a BMW, on an endurance test bed, and the exhaust headers are glowing orange. They'd run it, for ( I think, off memory) 36 hours, at redline, and it was still going strong.

If it was an air cooled engine, the motor would seize (lock up). It needs air rushing by the cylinder fins to cool and help dissipate the heat of the engine.
Like Silverstang said, on a water cooled engine, air has to be flowing through the radiator to cool the coolant. On a super hot day (over 100 degrees) the radiator fan might not be enough.
One thing people don't think about, is the oil in the engine can over heat. The piston & rings might not seize to the cylinder, but the oil will loose some luberication properties.
I saw a guy trying to look cool doing a smoke show (squeese the F brake, lock the F wheel, put the bike in gear and let the back wheel burnout until he's surrounded in smoke). He had the rpm's red-lined and a connecting rod exploded through the bottem of the crankcase!

Yes, it would over heat.
A motorcycle is usually "air cooled", and as it moves along, the engine loses heat as it dissipates into the atmosphere...
If its water cooled, then it still loses heat as air flows through it, going down the highway and byways...
Standing still, it will just build it up with out any way to dissapate the heat, thus, it has to fail after a good long time...
I wish you well...

Is possible, as there isn't sufficient airflow around the engine to help it dissipate the heat generated from the engine. If its coolant type cooling system, then it could from not getting enough airflow thru the radiator.

usually yes, but most newer bikes that are fuel injected will shut down at certain temperatures. The cooling system's fan can help with overheating but it cannot overcome a complete lack of movement, especially if you are constantly revving the motor.

Don't know a thing about motorcycles, but I do know that all engine have a heat limit untill that temperature is exceeded then that when the engine burns out and stops.

no most bikes stay cool because of the ari moving across the front of the engine when it is moving, bikes that are not liquid cooled overeat when they sit and are running

Most are air cooled and would burn up the motor.

it d-pends on the coolant system...
