The tread portion 2 is divided in the tire widthwise direction into five regions comprising the center tread region A, respective shoulder tread regions C, and respective intermediate tread regions B. A curved length in the tire widthwise direction of a tread surface of the center tread region A is in the range of 10 to 35% of the curved length in the tire widthwise direction of the entire tread surface, and the whole curved length in the tire widthwise direction of a tread surface of the shoulder tread regions C is in the range of 5 to 35% of the curved length in the tire widthwise direction of the entire tread surface. 100% Mod, i.e. the modulus at 100% elongation, of tread rubber forming the intermediate tread region B is larger than 100% Mod of tread rubber forming the center tread region A, and loss tangent of each shoulder tread region C is larger than loss tangent of the center tread region A.
A pneumatic motorcycle tire, including a pair of bead portions each having a bead core embedded therein, a pair of sidewall portions extending from the bead portions toward the outer side in the tire radial direction, and a tread portion extending over the respective sidewall portions, characterized in that:
