Abstract
A motorcycle tyre has a tread band () comprising a plurality of grooves that form a tread pattern including a module (T) replicated along a circumferential direction of the tyre () and having a predetermined circumferential length (C). The module (T) comprises a pair of circumferential grooves () arranged on opposite sides with respect to the equatorial plane (X-X) of the tyre (). Such circumferential grooves () extend along the circumferential direction of the tyre () for only part of said predetermined circumferential length (C) and define between them a central portion (A) of tread band () having a void to solid ratio substantially equal to zero and a predetermined axial width (A). The module (T) further comprises a plurality of transversal grooves () arranged on opposite sides with respect to the equatorial plane (X-X) at a distance from said equatorial plane (X-X) greater than that of said circumferential grooves () and a pair of first lateral annular portions (B) axially arranged between said circumferential grooves () and said plurality of pairs of transversal grooves (), each of said first lateral annular portions (B) comprising, in a position axially adjacent to the respective circumferential groove (), a respective part (B) of tread band having a circumferential length at least equal to that of said circumferential grooves () and a void to solid ratio substantially equal to zero. The tyre () has a curvature ratio lower than about 0.32.
