Abstract
A motorcycle tire includes a tread portion having a crown region extending across a tire equatorial plane, and a pair of shoulder regions located axially outside the crown region. A tread rubber includes a surface layer of first rubber arranged on the radially outer side, a bottom layer of third rubber arranged on the radially inner side, and a pair of middle layers of second rubber arranged between the surface layer and the bottom layer. In terms of a loss tangent tan δ at 100° C., the second rubber is greater than the first rubber and the third rubber. The surface layer and the bottom layer extend from one shoulder region to the other shoulder region through the crown region. Each middle layer extends through the respective shoulder region and is not arranged in the crown region. The surface layer and the bottom layer are directly connected in the crown region.
