Motorcycle tire

A motorcycle tire comprising a tread portion provided on each side of the tire equator with:

• primary oblique grooves arranged circumferentially of the tire and extending axially outwardly from a tread center region to at least the vicinity of the tread edge;
• and
• secondary oblique grooves each disposed between the circumferentially adjacent primary oblique grooves, and each having an axially outer end positioned axially inside the axially outer ends of the primary oblique grooves,
• wherein each of the secondary oblique grooves comprises:
• a pair of gradually widening parts respectively extending from two pointed extreme ends of the secondary oblique groove in its longitudinal direction toward an intermediate position between the two extreme ends, while gradually increasing the groove width measured perpendicularly to the longitudinal direction;
• and
• a pair of gradually narrowing parts which respectively extend from the gradually widening parts to the intermediate position, the groove widths of which gradually decrease from the gradually widening parts to the intermediate position, wherein
• each of the secondary oblique grooves has a pair of opposite groove edges, each groove edge being made up of a first part and a second part, wherein the first part is an arc being convex toward the outside of the secondary oblique groove and extending from one of said pointed two extreme ends to said intermediate position and wherein the second part is an arc being convex toward the outside of the secondary oblique groove and extending from the other of said pointed two extreme ends to said intermediate position.
