Motorcycle tire

A motorcycle tire comprising:

• a tread portion having a tread face,
• a pair of sidewall portions,
• a pair of bead portions,
• a carcass extending between the bead portions through the tread portion and the sidewall portions, and
• a tread reinforcing layer disposed radially outside the carcass in the tread portion, and having a developed axial width (Wa) of not less than 75% of a developed tread width (TWe) between tread edges of the tread face, each measured along the tread face in a tire meridian section,
• wherein
• the tread reinforcing layer is made up of a first halved reinforcing layer disposed on one side of the tire equator, and a second halved reinforcing layer disposed on the other side of the tire equator,
• the first halved reinforcing layer is composed of a helically-wound first strip of parallel reinforcing cords coated with topping rubber,
• the second halved reinforcing layer is composed of a helically-wound second strip of parallel reinforcing cords coated with topping rubber,
• the reinforcing cords of the first strip include an axially inside first reinforcing cord and an axially outside second reinforcing cord disposed axially outside the axially inside first reinforcing cord,
• the reinforcing cords of the second strip include an axially inside first reinforcing cord and an axially outside second reinforcing cord disposed axially outside the axially inside first reinforcing cord,
• in each of the first strip and the second strip, an initial elongation percentage a2 of the axially outside second reinforcing cord is greater than an initial elongation percentage a1 of the axially inside first reinforcing cord, wherein the initial elongation percentage of a reinforcing cord is an elongation of the cord in terms of a percentage when a load applied to the cord is increased from 2.5N to 49N,
• the first strip and second strip are helically wound from the tire equator to the respective edges of the tread reinforcing layer,
• in each of the first halved reinforcing layer and the second halved reinforcing layer, the first reinforcing cord and the second reinforcing cord are alternately arranged from the tire equator to the respective edges of the tread reinforcing layer, and
• the winding pitch P of the helically-wound first and second strips is larger in a central part and axially outer shoulder parts of the tread reinforcing layer than in middle parts of the tread reinforcing layer between the central part and the shoulder parts.
