Brake apparatus for two-wheeled vehicle

Abstract

A brake apparatus for a two-wheeled vehicle includes a hydraulic brake, which receives a hydraulic force to thereby generate a braking force, and a braking force control unit, which controls the braking force by increasing or decreasing the hydraulic pressure. The two-wheeled vehicle includes an engine disposed between a front wheel and a rear wheel. The engine includes a crankcase disposed downward thereof and a cylinder extending upwardly from a front portion of the crankcase. The braking force control unit is disposed in a space surrounded by the cylinder at a position forward thereof and the crankcase at a position downward thereof, respectively. The brake apparatus for a two-wheeled vehicle is capable of promoting enhanced maneuverability, achieving sufficient durability performance, and improving electric connection performance.
