Abstract:
1. A brake system for a motorcycle, comprising: a brake operating lever; a master cylinder operable in response to actuation of the braking actuation member; a wheel braking mechanism operable to apply a braking force to a wheel by hydraulic pressure operation; a main brake line connecting the master cylinder to the wheel braking mechanism; a hydraulic pressure modulator operable to generate hydraulic pressure corresponding to driving conditions and a braking operation of the motorcycle, and for modulating a supply of hydraulic pressure to the main brake line and discharging the hydraulic pressure from the main brake line, the hydraulic pressure modulator being connected in fluid communication with the main brake line; an electromagnetic on-off valve which is provided in the main brake line, the electromagnetic on-off valve controlling fluid flow between the master cylinder and the wheel braking mechanism; and a reaction force modulator operable to cause pseudo reaction force against the hydraulic pressure to function on the master cylinder corresponding to an amount of operation of the brake operation lever while the electromagnetic on-off valve closes the main brake line, wherein the reaction force modulator comprises:
