Motorbike tyre of the 'bias belted' type, able to guarantee the motorbike satisfactory stability both in a straight line, at high speed and zero camber angle and in a curve with a high camber angle. Such a tyre (1) comprises a tread (2), a crown reinforcement (5) radially on the inside of the tread (2) and comprising at least one crown layer (51, 52) comprising mutually parallel reinforces, forming, with the circumferential direction (XX') of the tyre, an angle of at most equal to 30 degrees in the equatorial plane (XZ), and a carcass reinforcement (6) radially on the inside of the crown reinforcement (5) and comprising at least two carcass layers (61, 62, 63), each carcass layer (61, 62, 63) comprising mutually parallel reinforces, forming, with the circumferential direction (XX'), an angle at most equal to 65 degrees in the equatorial plane (XZ) and crossed from one carcass layer to the next. The reinforces of each crown layer (51, 52) form, with the circumferential direction (XX'), an angle at least equal to 15 degrees and at most equal to 25 degrees in the equatorial plane (XZ) and the reinforces of each carcass layer (61, 62, 63) form, with the circumferential direction (XX'), an angle at least equal to 40 degrees and at most equal to 50 degrees in the equatorial plane (XZ).
