Beschreibung
Zusammenfassung:	A tyre for motor cycles has a belt layer (7) comprising aromatic polyamide fibre cords spirally wound around a carcass (6) substantially parallel to the equator (c) of the tyrel wherein the belt layer (7) is divided into a central region (M) and shoulder regions (S) at border (P) spaced apart in the axial direction by a distance of 0.25 times to 0.35 times the tread width (TW) from the equator of a tyre, and the initial modulus of elasticity of the belt cords in the central region (M) is larger than that of the cords in the shoulder regions (S).
