That is, the force of arms, the friction surfaces have the catalyst when the bike tilting to the left. Friction torque occurs at the surfaces of f Force (f l ´) made to front wheel.
Which is an arm of the force of friction on the ground when the bike axial tilt to the left of friction f the ground to the moment of force (f'l) acting on the front wheels.
Which is the arm of force of friction surface on axial when cycling tilted to the left. The friction f ground is born moment of force (f pixel L). Towards the front wheel.
