An adjustable lever assembly for a motorcycle master cylinder includes a first element pivotally connected to the master cylinder, and a manually operable second element pivotally connected to the first element. An adjuster rotatably mounted on the second element can be turned to adjust the angular rest position between the first and second elements.

The invention claimed is: 1. An adjustment device for motorcycle master cylinders, said device comprisingfirst operating means pivotally associable to a cylinder-piston unit of a motorcycle master cylinder, so as to impart an actuation movement to said cylinder-piston unit, said first operating means comprising coupling counter-means;second operating means pivotally connected to said first operating means and suitable for imparting a thrust movement to said first operating means for carrying out said actuation means of said first operating means, said second operating means further comprising a first end, two side surfaces protruding from said first end and arranged in position substantially parallel to one another, said two side surfaces delimiting a seat recessed between said two side surfaces; said device further comprisingadjustment means, arranged between said first operating means and said second operating means, said adjustment means being coupled with said second operating means and being pivotally housed into said seat, said adjustment means further being suitable for adjusting the relative angular position between said second operating means and said first operating means, said adjustment means further having a side skirt comprising coupling means suitable for geometrically and selectively coupling with said coupling counter-means of said first operating means for defining at least one angular rest position between said first operating means and said second operating means for imparting said thrust movement from said second operating means to said first operating means, operating portions comprising thrust surfaces accessible by an operator for a rotation of said adjustment means, said rotation being suitable for selecting the coupling between one of said coupling means and said coupling counter-means; and wherein, moreover, said coupling means and said operating portions are comprised between planes defined by said side surfaces of said seatwherein said adjustment means have a rotation hole and a first rotation pin, axially housed in said hole and cooperating with said first end, for holding said adjustment means in said seat and for allowing rotation of said adjustment means about said first pin, when said coupling means are uncoupled from said coupling counter-means andsaid thrust movement of said second operating means to said first operating means is actuated along an angular actuation stroke and said second operating means are also actuable along an angular adjustment stroke, opposed to said angular actuation stroke, for releasing said coupling means from said coupling counter-means and allowing rotation of said adjustment means, and further comprisingelastic means substantially housed into said seat and axially associated with said adjustment means by said first pin, said elastic means biasing said second operating means toward said angular rest position when said second operating means are actuated along said angular adjustment stroke.
