The system has a target associated in rotation to a front wheel (1) of a two-wheeler, and a Hall effect sensor (7) to deliver an information of rotation speed of the wheel. The target is formed by a crenulated peripheral portion (6) of a brake disc associated to the wheel. The sensor is disposed radially in opposite to the crenulated peripheral portion of the brake disc.
