摘要： A tire for a motorcycle comprising a tread, sidewalls extending inwardly from both ends of the tread in a radial direction, bead portions positioned at the radially inward ends of the sidewalls, a toroidal reinforcement carcass composed of reinforcement cords which extend approximately parallel with each other in the radial direction of the tire and of which both end portions are turned up around bead cores, a breaker arranged on the radially outer side of the carcass, the breaker comprising reinforcement tire cords whose tensile strength is not less than 7 g/d and initial modulus is not less than 200 g/d laid at angles of 10.degree. to 45.degree. to the circumferential direction, and a band over the breaker and having a width greater than the breaker so as to axially extend past the outermost edges of the breaker and comprising parallel reinforcement cords laid at angles of 10.degree. to 25.degree. to the circumferential direction, the reinforcement cords of the band having a modulus less than the modulus of the reinforcement cords of the breaker.The tire has resistance to wear, good grip, and stable high speed running properties.
摘要翻译：一种用于摩托车的轮胎，包括胎面，沿径向从胎面的两端向内延伸的侧壁，位于侧壁的径向内端的胎圈部分，由增强帘线构成的环形加强胎体，所述增强帘线彼此平行延伸在轮胎的径向方向上，并且两个端部围绕胎圈芯卷起，设置在胎体的径向外侧的断路器，该断路器包括抗拉强度不小于7g / d的加强轮胎帘线，初始模量不小于200g / d，与圆周方向成10°至45°的角度，并且在断路器上方具有宽度大于断路器的带，以便轴向延伸穿过断路器的最外边缘并且包括与圆周方向成10°至25°角的平行加强帘线，带的增强帘线的模量小于断路器的增强线的匝数。轮胎具有耐磨性，良好的抓地力和稳定的高速运行性能。

摘要： Radial tires for motorcycles comprising a tread portion, side wall portions, bead portions, a carcass, a breaker, and optionally a reinforcing cord layer arranged outside the carcass and extending from one bead portion to the other bead portion and bead apexes made of a hard rubber, said tread portion having a plurality of longitudinal grooves in the circumferential direction at an angle of at least 5.degree. with respect to the cords of the most outer ply of the breaker. The motorcycle radial tires of the invention have an improved transverse stiffness at the side wall portions and moreover do not cause cracks at the bottom of the grooves in the tread portion.
