Off-road motorcycle tyre

A motorcycle tyre comprising:

• a carcass structure comprising a crown portion and two lateral portions axially opposed to each other, each lateral portion being associated with a respective bead structure;
• a belt structure applied in a radially outer position with respect to the carcass structure;
• and
• a tread band applied in a radially outer position with respect to the belt structure,
• wherein:
• said carcass structure comprises at least two radially superimposed carcass plies comprising, in each ply, reinforcing cords substantially parallel with each other, oriented according to inclined directions with respect to an equatorial plane of the tyre and opposed to the reinforcing cords of the radially adjacent ply;
• said belt structure comprises at least one belt layer comprising at least one reinforcing cord disposed so as to form a plurality of windings disposed according to a substantially null angle with respect to the equatorial plane of the tyre, wherein said at least one belt layer extends at most on 70% of a lateral development of said crown portion of said carcass structure;
• and
• said tread band comprises a plurality of blocks circumferentially spaced by traverse grooves.

A motorcycle comprising a first tyre fitted on a rear wheel and a second tyre fitted on a front wheel, said first tyre and said second tyre comprising:

• a reinforcing structure comprising at least two radially superimposed carcass plies, each of said plies comprising reinforcing cords substantially parallel with each other, oriented according to inclined directions with respect to an equatorial plane of said first and second tyre and opposed to the reinforcing cords of a radially adjacent ply;
• and
• a tread band comprising a plurality of blocks circumferentially spaced by transverse grooves,
• wherein said reinforcing structure of said first tyre further comprises at least one belt layer disposed between said at least two carcass plies and said tread band, said belt layer comprising at least one reinforcing cord disposed to form a plurality of windings disposed according to a substantially null angle with respect to the equatorial plane of said first tyre, said reinforcing layer extending only on a central sub-portion of a crown portion of said first tyre.

A method for controlling a motorcycle comprising a first tyre fitted on a rear wheel and a second tyre fitted on front wheel, said first tyre and said second tyre comprising:

• a reinforcing structure comprising at least two radially superimposed carcass plies, each of said plies comprising reinforcing cords substantially parallel with each other, oriented according to inclined directions with respect to an equatorial plane of said first and second tyre and opposed to the reinforcing cords of a radially adjacent ply;
• and
• a tread band comprising a plurality of blocks circumferentially spaced by transverse grooves;
• said method comprising:
• engaging with said motorcycle a bending trajectory;
• orienting said motorcycle according to an oversteer angle with respect to said bending trajectory, and orienting said front wheel according to a countersteer angle with respect to said bending trajectory;
• and
• providing an accelerating torque to said rear wheel in at least a portion of said bending trajectory, while said motorcycle is disposed according to said oversteer angle,
• wherein:
• said reinforcing structure and said blocks of said first tyre react to said accelerating torque so as to provide said rear wheel with a traction thrust directed according to said oversteer angle;
• said reinforcing structure and said blocks of said second tyre react to said countersteer angle so as to compensate a lateral drift of said motorcycle and said oversteer angle, and keep said motorcycle on the bending trajectory;
• and
• said reinforcing structure of said first tyre further comprises at least one belt layer disposed between said at least two carcass plies and said tread band, said belt layer comprising at least one reinforcing cord disposed to form a plurality of windings disposed according to a substantially null angle with respect to the equatorial plane of said first tyre, said reinforcing layer extending only on a central sub-portion of a crown portion of said first tyre, so as to increase a stiffness of said central sub-portion of said first tyre, and consequently contribute to said traction thrust.
