BRAKE SYSTEM FOR MOTORCYCLE, AND MOTORCYCLE

The present invention has a purpose of improving mountability of a brake system capable of performing slip control operation of a front wheel and a rear wheel to a motorcycle. The present invention further has a purpose of obtaining a motorcycle that includes such a brake system. In a front-wheel braking section (), a friction force, which is applied to a front wheel () by a first friction application device (), varies according to a hydraulic pressure of a brake fluid in a master cylinder () during service braking and varies by control of a hydraulic pressure adjustment mechanism ( and the like) by a controller () during the slip control operation. In a rear-wheel braking section (), a friction force, which is applied to a rear wheel () by a second friction application device (), varies by control of an actuator () by the controller () during the service braking and during the slip control operation.
