Tire for a motorcycle

A tyre for a motorcycle comprising a carcass extending between bead cores of bead portions via a tread portion and sidewall portions, wherein

• when (I) the tyre mounted on a standard rim and inflated to a standard inner pressure is in contact with a flat surface with a camber angle of 40 degrees, (II) a load (F) applied to the tyre is increased from zero, and (III) a curve is obtained by plotting a displacement (Δx) in a tyre axial direction and a displacement (Δy) in a tyre radial direction of a position of one of tyre tread edges closer to the flat surface, the displacements being from a reference position when the load (F) is zero,
• inclination of the curve increases as the load (F) increases at least in a range where the load (F) is not more than 78% of a maximum load capacity load of the tyre,
• each of the bead portions is provided with a bead apex rubber extending in the tyre radial direction from a respective one of the bead cores,
• a height (H1) in the tyre radial direction of each of the bead apex rubbers from a bead base line is in a range of from 0.70 to 1.40 times a height (H2) in the tyre radial direction of a rim flange of the standard rim from the bead base line,
• a distance (Lj) in the tyre axial direction between each of maximum width positions (Q) of the carcass and a center of gravity point (G) of a respective one of the bead cores is in the range of from 0.65 to 0.80 times a distance (LJ) in the tyre axial direction between each of the tread edges (Te) and the respective center of gravity point (G),
• a height (Hj) in the tyre radial direction of the carcass between each of the maximum width positions (Q) and the bead base line is in a range of from 0.50 to 0.85 times a height (HJ) in the tyre radial direction between each of the tread edges and the bead base line,
• a band layer formed of a band cord spirally wound is arranged on an outer side in the tyre radial direction of the carcass and inside of the tread portion,
• a width (Wb) in the tyre axial direction of the band layer is in a range of from 0.5 to 0.95 times a tread width (TW),
• the carcass consists of a single carcass ply,
• the carcass ply has a ply main body portion and ply turned up portions,
• the ply turned up portions terminate between the maximum width positions (Q) and the tread edges in the tyre radial direction, and
• the ply turned up portions each terminate between a respective axially outer end of the band layer and a respective one of the tread edges in the tyre axial direction.
