Abstract: A motorcycle tyre with a low void-to-rubber ratio while providing a stiffness suitable for good performance on dry ground and on track. A tread band with grooves is arranged to provide a draining effect without structurally weakening the tread band. According to one aspect, the tread band has a tread pattern with two pairs of grooves having segments or portions that produce a warming effect when the compound of the tread band is cold. The tread band provides grip to the ground and limited local warming when the compound of the tread band is at the operating temperature or when driving on dry ground, to provide stiffness and readiness of response.

Abstract: A tyre that can be fitted to the front of a motorcycle. The tyre has a high void-to-rubber ratio and includes grooves located asymmetrically across the equatorial plane of the tyre, arranged substantially orthogonally to the equatorial plane of the tyre at the equatorial plane itself. According to one aspect, the grooves are close to one another in the circumferential direction of the tyre to increase their number in a footprint area of the tyre.

Abstract: A motorcycle tyre intended to be fitted to the rear wheel of a motorcycle. The motorcycle tyre has a tread pattern with a high void-to-rubber ratio that provides a suitable draining. The tread pattern has pairs of primary grooves to carry out the draining function of the tyre, and arranged substantially according to the stress lines of the tyres to reduce the probability of triggering uneven wear. Also included are secondary grooves having a reduced dimension, in terms of both extension and width, arranged between the primary grooves to increase the grip of the tyre to the ground. Orientation of the secondary grooves increases stabilizing features against drift forces acting on the tyre, particularly in low or very low friction conditions.

Abstract: A motorcycle tyre (1) has a tread band (1) comprising a plurality of grooves that form at least part of a tread pattern including a module (T) replicated along a circumferential direction and having a predetermined circumferential length (Cl). The module (T) comprises a pair of circumferential grooves (20) arranged on opposite sides with respect to the equatorial plane (X-X) of the tyre (1). Such circumferential grooves (20) extend along the circumferential direction for at least part of said predetermined circumferential length (Cl) and define between them a central annular portion (A) of tread band (8) having a void to solid ratio substantially equal to zero and a predetermined axial width (Al). The module (T) further comprises a pair of first lateral annular portions (B) arranged on opposite sides with respect to the equatorial plane (X-X) in an axially outer position with respect to said pair of circumferential grooves (20) and each having a void to solid ratio substantially equal to zero, and a plurality of transversal grooves (30, 31, 32, 33) arranged on opposite sides with respect to the equatorial plane (X-X), in an axially outer position with respect to said pair of first lateral annular portions (B).
