What is a motorcycle?

Apart from being a commuter or sport instrument. A piece of art. It’s even more. Let’s see from a technical point of view.
The internal combustion engines generally work with an efficiency up to  30-40%. The rest, 60-70 percent of the energy that an engine produces is not translated into motion but simply into heat. So the motorbike is a machine that produces heat. Therefore it is also a machine designed to cool itself !
It gets all the power by burning liquid into gas. And that has to flow through its system, so, it is also a flow technology based design.
But it’s even more than that. It has two wheels, yet when running it is stable, and maintains a straight line of motion. It’s a gyroscope ! Given not only by the mass of the wheels, but even more importantly the crank shaft’s rotation. This effect actually plays a huge role in defining the riding experience (for example, 4 cylinders has a wider and heavier crankshaft then v2).
The story doesn’t end here. It has lights, it communicates, ignites, and does even more that requires electricity. So it is an electric device too!
And… It won’t go anywhere without a rider. A good rider perhaps. But that’s another story. Now we can see, that it is in fact a very complex organism, that requires a fine balance from many aspects to operate smoothly and sustainably.
