The invention has a purpose of obtaining a brake hydraulic pressure controller capable of securing durability with a simple configuration and a motorcycle brake system. The brake hydraulic pressure controller is a hydraulic pressure controller for a vehicle brake system and includes: a base body that is formed with a channel filled with a brake fluid therein; a hydraulic pressure regulation valve that has a plunger and opens/closes the channel by translatory movement of said plunger; a drive coil that has a hollow section, is vertically provided in the base body in a state where one end of the plunger is inserted in said hollow section, and causes the translatory movement of the plunger to drive the hydraulic pressure regulation valve; and a coil casing that accommodates the drive coil. The coil casing includes a wall that covers at least a part of an apex of the vertically-provided drive coil, and the drive coil is pressed toward the base body by a projection formed in the wall.
