<p>Improved brake disc especially suitable for motor-cross and trial motorcycles, with the central feature that the periphery (1), forming the brake plate, has a set of notches (11-12) on the inside and outside borders or edges, to reduce the weight of the disc and facilitate its cooling by increasing its area, said notches being distributed evenly around the disc periphery to maintain its centre of gravity in relation to its geometrical centre, and with said notches fulfilling the role of the traditional weight-reducing openings or drillholes, while preventing the problem of the accumulation of mud, typical of the latter. <IMAGE></p> |
