A motorcycle tire having a rotation direction specified, the motorcycle tire including one or more land portions on a center part (TC) of the tire occupying 50% of a length of the tire on a tread surface of the tire along a periphery of the tread surface , the one or more land portions divided by a plurality of width direction grooves extending in a tire width direction and a plurality of circumferential direction grooves extending in a tire circumferential direction, the center part (TC) having an equatorial plane of the tire as a center of the center part (TC), wherein at least one of the land portions is configured such that, in a circumferential cross-section of the tire , wherein a reference line is a section (L2) perpendicular to a shortest virtual line (L1) connecting a first boundary (b1) and a second boundary (b2), the first boundary (b1) being between a bottom part (u1) of the plurality of width direction grooves and one side wall of the land portion at a kick-out side in the rotation direction of the tire , the second boundary (b2) being between the bottom part (u2) of the plurality of width direction grooves and other side wall of the land portion at a step-in side in the rotation direction of the tire , both the side walls facing the respective width direction grooves , the bottom parts (u1, u2) being of the width direction grooves , the section (L2) passing through a third boundary (v1) between a surface of the land portion and the one side wall of the land portion at the kick-out side in the rotation direction of the tire an inclination angle (θ1) of the side wall at the kick-out side to the reference line is ranged from -10° to 5° inclusive, where a direction of inclination toward the land portion is defined as a negative direction, and the inclination angle (θ1) of the side wall at the kick-out side is smaller than an inclination angle (θ2) of the side wall at the step-in side to a section (L3), among the perpendicular lines, which passes through the boundary (v2) between the surface of the land portion and the side wall at the step-in side. at least one of the land portions is configured such that, in a circumferential cross-section of the tire , wherein a reference line is a section (L2) perpendicular to a shortest virtual line (L1) connecting a first boundary (b1) and a second boundary (b2), the first boundary (b1) being between a bottom part (u1) of the plurality of width direction grooves and one side wall of the land portion at a kick-out side in the rotation direction of the tire , the second boundary (b2) being between the bottom part (u2) of the plurality of width direction grooves and other side wall of the land portion at a step-in side in the rotation direction of the tire , both the side walls facing the respective width direction grooves , the bottom parts (u1, u2) being of the width direction grooves , the section (L2) passing through a third boundary (v1) between a surface of the land portion and the one side wall of the land portion at the kick-out side in the rotation direction of the tire an inclination angle (θ1) of the side wall at the kick-out side to the reference line is ranged from -10° to 5° inclusive, where a direction of inclination toward the land portion is defined as a negative direction, and the inclination angle (θ1) of the side wall at the kick-out side is smaller than an inclination angle (θ2) of the side wall at the step-in side to a section (L3), among the perpendicular lines, which passes through the boundary (v2) between the surface of the land portion and the side wall at the step-in side. <EOS>
