ELI5: Why is the steering inverted on motorcycles at high speeds?

E.g., when I turn my handlebars left and I'm going 40+ mph, the bike tilts and turns to the right.

You are turning the front wheel to the left, the wheel goes left slightly, and the entire bike (and you) keeps going straight. The bike goes from looking like 

this: l 

to looking like this: / 

See how the bottom of the bike moves to the left? you have turned the front wheel slightly left, moving the bottom of the bike to the left, and now you and the top of the bike are leaning right. In order to keep from falling over, you bring the handlebars to the right and make the turn to the right.

This happens the same at any speed, but feels more drastic at higher speeds. Most people don't think about this motion when you turn, but it happens in motorcycles and bicycles. This is just how they turn.
