PROBLEM TO BE SOLVED: To provide a pneumatic tire for a motorcycle capable of improving stability in straight running when the motorcycle runs straight on a road surface while maintaining satisfactory grip performance during cornering by making distribution of moduli of tread rubber constituting a tread part proper. SOLUTION: This pneumatic tire for the motorcycle is provided with a pair of bead parts 1 having a buried bead core, a pair of side wall parts 2 extended onto an outer side in the radial direction of the tire from the bead parts 1, and the tread part 3 extended across and between both of the side wall parts 2. This tread part 3 is constituted by at least four tread part regions having moduli of the rubber constituting adjacent regions which are different from each other when viewed in a cross section in the direction of tire width. The modulus of the rubber constituting the central tread part region 5 including an equatorial plane 4 of the tire among the tread part regions is larger than the modulus of the rubber constituting the other tread part regions 6.
