Tyre for motorcycles

A tyre for motorcycles, having a tread band comprising a central annular portion symmetrically located astride an equatorial plane;

• two lateral annular portions located on axially opposite sides with respect to the central annular portion;
• and two shoulder annular portions located on axially opposite sides with respect to the lateral annular portions,
• the central annular portion having an axial extension not greater than 25% of an axial development of the tread band;
• each shoulder annular portion having an axial extension not greater than 20% of the axial development of the tread band;
• each lateral annular portion having an axial extension not greater than 35% of the axial development of the tread band;
• the tread band comprising a plurality of grooves adapted to define a tread pattern, the grooves of the tread pattern altogether defining a void-to-rubber ratio lower than 8% on said tread band;
• the tread band comprising a module repeated along a direction of circumferential development of the tyre comprising:
• at least two substantially longitudinal grooves oppositely inclined with respect to the equatorial plane of the tyre, wherein:
• the first substantially longitudinal grooves mainly extend in the lateral annular portions and comprise, moving axially away from the equatorial plane of the tyre, at least three substantially straight and substantially consecutive segments, wherein a first segment has an inclination with respect to the equatorial plane adapted to form an angle greater than 150°, and wherein the first segment has a length measured along an extension thereof greater than 4% of the circumferential development of the tyre;
• a second segment has a length measured along an extension thereof smaller than a length of the first segment;
• the second segment extending in a radial region of a lateral annular portion defined by radial angles between +/−5° and +/−25°, in a case of a tyre intended to be mounted on a rear wheel of a motorcycle, and between +/−5° and +/−20°, in a case of a tyre intended to be mounted on a front wheel of a motorcycle.
