1. A method of anti-lock braking of a motorcycle having front and rear wheels each having a brakes, comprising the steps of:

  • a) applying braking pressure to said front and rear wheel brakes,b) measuring the value of rotational retardation and slip of the front wheel and the rear wheel of the motorcycle,c) comparing the value of the measured rotational retardation and slip of the front and rear wheels with a predetermined threshold value,d) maintaining or reducing said braking pressure when said measured value exceeds a predetermined threshold value,e) applying for a predetermined period of time to the brake of the rear wheel a higher brake pressure than to the brake of the front wheel,f) comparing, at the time when a higher brake pressure is applied to the brake of the rear wheel than to the brake of the front wheel, rotational speeds and rotational retardations of the front and the rear wheels, andg) adjusting said threshold value in response to said comparison.
