The thickness of the tyres and the natural balance.

counter steer input of the rider through handle bars, and gyroscopic effect of the wheels rotating,
accelerating stands the bike up and can help to keep balance when turning
at low speeds its mainly the riders own balance and the bike is kept nearly up right, and again wobbles can be caught by acceleration

in a straight line with the bike upright the rider is not needed for balance. thats how stunt men can skate along the ground behind being towed by the bike like a water skier and the bike stays upright till they get back on it

I assume you mean in a straight line.

Without imput from the rider the bike on it`s own would fall over. These minute imputs are the same when riding a kids scooter or a push bike. To get the idea, sit on a stationary push bike, as you lift your feet off the ground, you may well hold the bike upright for a few seconds, but you will slowly lose balance and begin to fall, you naturally counteract this movement by turning your handlbars into the direction of fall to regain balance. That`s how a motor cycle stays upright

The rotating mass of the wheels creates a gyroscope effect, meaning that a rotating object will try to remain in a straight line. The natural tendency of the wheels to stay in a vertical position is what keeps a motorcycle upright.

Ever played with a gyroscope when you were a kid? Same here - the wheels spin (along with the engine and other bits) and they produce the force that keeps the bike upright.

Main reason novice bikers often fall over at the traffic lights :)

motorbikes stay balanced by the use of the gravity of your body to the motorbikes.your the one controlling it.Motorcycles must be leaned in order to turn. This lean can be induced by a method known as countersteering, in which the rider turns the handlebars in the direction opposite of the desired direction of turn. In other words, press forward on the handgrip in the desired direction—press right to go right, press left to go left. This concept is counter-intuitive and often very confusing to novices—and even to many experienced motorcyclists.Important factors of a motorcycle's ergonomic geometry that determine the seating posture include the height, angle and location of footpegs, seat and handlebars. Likewise, factors in a rider's physical geometry that contribute to seating posture include torso, arm, thigh and leg length, as well as overall rider height

If you are not a motorcyclist then you will struggle to understand

It is the same principal as a push bike. If you can ride a pushbike then once you have mastered the controls you will be able to ride a motor bike

Lady Domina has it, gyroscopic forces are difficult to deflect, on a flat surface with no wind a motorcycle, that is moving at a little above walking pace, will stay upright until another force acts against it.

It's called "Angular Momentum".
The rotating tires have a special kind of inertia that makes it difficult to change the direction of the spinning tires.

This is the way gyroscopes work. Look it up in wikipedia.

Mine uses an unbalanced operator, which cancels other effects, leaving the bike upright.

Usually through momentum and a series of minute adjustments by the rider.
