    • A motorcycle body frame includes a main frame including a head pipe for supporting a front suspension at the front end thereof, a single leading frame portion extending rearwardly from the head pipe, and a rear frame portion for supporting a rear wheel suspension. The rear frame portion extends substantially downwardly from a rear part of the leading frame portion. The main frame, cast from an aluminum alloy, includes two component parts arranged front-to-rear. For example, a front frame portion is provided, and a rear frame portion is fixed to the rear side of the front frame portion. The leading frame portion has a small section portion, where the main frame is smallest in sectional area, disposed substantially centrally in the longitudinal direction thereof. The two component parts of the frame are joined at a coupling portion of the main frame situated in back of the small section portion.
    • 摩托车车身框架包括主框架,该主框架包括用于在其前端支撑前悬架的头管,从头管向后延伸的单个前框架部分和用于支撑后轮悬架的后框架部分。 后框架部分从引导框架部分的后部基本上向下延伸。 由铝合金铸造的主框架包括前后布置的两个部件。 例如,设置前框架部分,并且后框架部分固定到前框架部分的后侧。 引导框架部分具有小截面部分,其中主框架的截面积最小,其纵向方向大体上居中。 框架的两个组成部分在位于小部分的后面的主框架的联接部分处连接。

    • A vehicle frame structure includes a pair of main frames, one of the pair of frames extending on left side of a vehicle, and the other on the right side, from the head pipe rearwards in an overall sealed cross sectional structure. At least a portion of each main frame includes a frame upper stage and a frame lower stage, each stage made up of a closed, sealed cross sectional structure. At least a portion of each main frame further includes an outer plate and an inner plate joined into an integrated piece with the frame upper stage and the frame lower stage. The plates are installed so as to extend over both sides of the frame upper stage and the frame lower stage. The frame structure provides a well-balanced high-strength main frame, and high strength in portions which join the main frame and head pipe.
    • 一种车架结构包括一对主框架,一对框架中的一个框架在车辆的左侧延伸,另一个在右侧,以总体密封的横截面结构从头管道向后延伸。 每个主框架的至少一部分包括框架上段和框架下段,每个阶段由封闭的密封横截面结构构成。 每个主框架的至少一部分还包括一个外板和一个内框,该内板与框架上层和框架下层相连接成一体。 板被安装成在框架上部和框架下部的两侧延伸。 框架结构提供平衡良好的高强度主框架,高强度部分连接主框架和头管。

    • An exhaust valve and a catalyst can be easily disposed of in a simple manner. The interior of a triangular muffler is partitioned into three expansion chambers. A manifold pipe is connected to the second, middle expansion chamber sideways from a lower portion thereof and is accommodated therein so as to face upward. A catalyst is accommodated in the interior of the manifold pipe. Exhaust gas flowing out from an open end of the manifold pipe expands into the second chamber. A short-circuiting aperture is formed in a second separator and is opened and closed with an exhaust valve installed within the third chamber. The exhaust valve is normally closed by a spring. When the exhaust pressure reaches a predetermined magnitude, the exhaust valve opens automatically, allowing the exhaust gas to flow out into the third chamber through the short-circuiting aperture, thereby controlling the exhaust pressure.
    • 排气阀和催化剂可以容易地以简单的方式处理。 三角形消声器的内部被分隔成三个膨胀室。 歧管与第二中间膨胀室从其下部侧向连接并容纳在其中以朝向上方。 催化剂容纳在歧管管的内部。 从歧管的开口端流出的废气膨胀到第二室中。 在第二分离器中形成短路孔,并且用安装在第三室内的排气阀打开和关闭短路孔。 排气阀通常由弹簧关闭。 当排气压力达到预定值时,排气阀自动打开,排气通过短路孔流出到第三室,从而控制排气压力。
