Explained here: https://www.facebook.com/share/v/18kaSRvWSp/? The cornering equation is tan (theta) = V^2 / g R Theta is the lean angle V is velocity or speed g is the gravitational constant (9.81 m/s^2) R is the turn radius in metres Rearrange for R and the radius of your turn is proportional to the velocity squared divided by the lean angle. So what? Well, it helps to understand the physics behind riding so you know what happens and why. It also helps you understand how to approach things like
