A motorcycle tire set comprising:

• a front-wheel tire;
• and
• a rear-wheel tire,
• wherein
• each of the front-wheel tire and the rear-wheel tire comprises a tread portion, a toroidal carcass, a band layer arranged outwardly in a tire radial direction of the carcass in the tread portion, and a tread rubber arranged outwardly in the tire radial direction of the band layer,
• the carcass comprises a carcass ply comprising a plurality of carcass cords,
• the band layer comprises a jointless band ply in which a band cord is wound spirally in a tire circumferential direction at an angle equal to or less than 5 degrees, and
• the tread rubber comprises an outer surface between tread edges,
• the outer surface of the tread rubber consists of
• a crown rubber portion formed of a rubber material and disposed in a tread crown region so as to cross a tire equator, and
• a pair of shoulder rubber portions formed of a rubber material different from the rubber material of the crown rubber portion and each extending in a tire axial direction from the crown rubber portion to a respective one of the tread edges,
• wherein
• an angle θ1 of the plurality of carcass cords of the front-wheel tire is equal to or less than 65 degrees with respect to the tire circumferential direction,
• a rubber hardness Hc2 of the crown rubber portion of the rear-wheel tire is greater than a rubber hardness Hc1 of the crown rubber portion of the front-wheel tire,
• in the front-wheel tire, the rubber hardness Hc1 of the crown rubber portion is greater than a rubber hardness Hs1 of the pair of shoulder rubber portions,
• in the rear-wheel tire, a rubber hardness Hs2 of the pair of shoulder rubber portions is greater than the rubber hardness Hc2 of the crown rubber portion, and
• the rubber hardness Hc1 of the crown rubber portion of the front-wheel tire ranges from 58 to 68.
