1. A motorcycle tire comprising a tread that comes into contact with a road surface at a tread surface thereof, wherein
the tread includes a plurality of blocks including a center block located on an equator plane and a side block located outward of the center block in an axial direction,
each of the plurality of blocks includes a land surface that forms a part of the tread surface,
in the tread surface, a total area of the land surfaces is smaller than a total area of a portion other than the land surfaces,
a complex elastic modulus at a maximum strain amplitude of 1% and a temperature of 70° C. of each block, according to JIS K6394 as measured with at least an initial strain of 0.15% and a frequency of 10 Hz, is not less than 10.0 MPa, and
a 300% modulus at a temperature of 75° C. of each block, according to JIS K6251, is not greater than 6.0 MPa.
