# Forces on a motorcyclist

I have never studied any form of mathematics other than through 'getting through life' and working stuff out and trying to understand the mechanics/ physics in terms I understand. Non scientific / mathematical terms but words in English.
I have a few questions I would like to ask a physicist to explain in words and terms I understand.
Along the way I am sure I could get to know some interesting characters and learn your terms to my thinking.

Q. What are all the forces in play with a motorcyclist negotiating a corner at speed, and leaning into the corner by moving his/ her mass off the bike (and down), in order to reduce the angle of lean of the bike itself.
Thank you.

Consider the tyres to be radial with as much traction on it's overall surface, whilst in a constant state of rest.
Consider the centre of gravity to be midway between the two wheels in a constant state of rest.
The rider weighs half as much as the bike.
What else?

Taking your question literally ("all the forces in play") there are three forces:
