A pneumatic tire for a motorcycle, wherein the tire is optimized in the ground contact shape and the ground contact pressure distribution during high-speed running to achieve excellent driving stability, is provided. Furthermore, a pneumatic tire for a motorcycle, wherein the tire is optimized in the ground contact shape and the ground contact pressure distribution during high-speed running to realize excellent gripping force to stabilize the behavior of the tire near its cornering limit and excellent cornering ability, is provided. Provided is a pneumatic tire for a motorcycle, which employs a multifilament-twist polyketone fiber cord, as a reinforcing material, having a total dtex value of 1000 to 20000 dtex per cord and satisfying the relationships represented by the following Expressions (I) and (II): sigma>=-0.01E+1.2 (I) sigma>=0.02 (II) (wherein, E is an elastic modulus (cN/dtex) at 25° C. under a load of 49 N, and sigma is a heat shrinkage stress (cN/dtex) at 177° C.).
