Abstract: An integrated handlebar extension and master cylinder apparatus for use on the handlebar of an associated motorcycle is provided. The integrated handlebar extension and master cylinder apparatus includes a main body member with a connection interface for selectively connecting the apparatus onto the handlebars of an associated motorcycle. A master cylinder unit is formed integrally with the main body member and has an elongate bore defining a first longitudinal axis. A piston is disposed within the bore and is slidable relative to the master cylinder unit along the first longitudinal axis. A trigger member is pivotably movable relative to the master cylinder unit and is adapted on a first end to receive an actuation force and on a second end to cause relative movement between the master cylinder unit and the piston in response to the actuation force. A handlebar portion extends along said first longitudinal axis on a side of said main body member opposite from said connection interface.
