A service brake caliper and the parking brake caliper (hereinafter called P caliper) are supported by a swing arm rotatably supporting the rear wheel. The service brake caliper and the P caliper are configured to brake the brake disc. In the rear brake device of the vehicle, the service brake caliper and the P caliper are fixed to a stay member, the stay member being supported by the swing arm. At least some of the service brake caliper and the P caliper are arranged in positions forward of a vehicle body and upward of the vehicle body from an axle of the rear wheel. A first boss and a third boss are arranged on a straight line passing through a center point of the axle.

Rear brake device of vehicle

A collecting exhaust pipe has a contour body and partition wall members. The contour body has a pair of contour members connected with each other. The partition wall members are joined to the contour body and sandwiched between the contour members. A plurality of swelling portions, which are swelled toward the other contour member side, are formed on at least one of the contour members so as to form tubular undulations that extend continuously along a plurality of the primary exhaust pipes, and are shaped so as to join on the downstream side of the contour body on at least one outer surface of the contour body. The partition wall members extend from the upstream portion to the downstream side of the contour body, and are joined to the contour body at the location spaced from the top portions of the swelling portions.

Exhaust device for motorcycle

A saddle-ride type vehicle that allows easy axle adjustment even if the exhaust system has such a structure wherein a muffler is close to an axle of a rear wheel. The exhaust system includes a tubular muffler connected to an exhaust pipe for discharging the exhaust of an engine. In the exhaust system, the muffler is disposed laterally to a rear wheel rotatably supported by swingarms via an axle. An end cap covering a muffler rear end portion of the muffler is detachably and attachably provided on the muffler rear end portion with the end cap being disposed on a vehicle outer side of the axle at such a position that the axle is invisible in a side view of the vehicle.

Exhaust system of saddle-ride type vehicle

A saddle type vehicle includes a throttle body arranged while restraining the effect of the exhaust air of a radiator while restraining the vehicle width even though the radiator is large. A radiator includes a mixed flow fan which flows exhaust air from the radiator rearwardly and outwardly in the vehicle width direction and a motor configured to rotate the mixed flow fan on the back surface thereof. A throttle body is arranged rearwardly of the mixed flow fan so as to be overlapped with the mixed flow fan in a front view.

Saddle type vehicle

To enable immediate and easy-to-understand confirmation of heat-dissipation capability only by entering shape data of a radiator without switching screens. Shape data input sections and a shape display section for a radiator, and a graph display section which displays the calculated result as a graph are adapted to be displayed on the identical screen of the screen device. The pattern diagram of a radiator shape and the result of heat-dissipation capability can be seen on the graph simultaneously only by entering the shape data of the radiator without switching the screen.

Radiator heat-dissipation simulation system

An object of the invention is to improve the motorcycle radiator arranging construction with a view to improving the external appearance characteristic of a motorcycle. In a motorcycle having a water-cooled engineinstalled thereon, a radiatoris arranged erect in a spacedefined between the engineand a rear wheelin such a manner that a front surfacethereof is directed in a longitudinal direction of the vehicle and is supported on a body frame, whereby the radiatoris made difficult to see from the outside compared with a case where the radiator is arranged at the front of the body frame to thereby make conspicuous, for example, the design of the engine.

Motorcycle radiator arranging construction

An engine-supporting structure for a motorcycle, in which a collar can be removed to perform engine maintenance, and can be suitably re-mounted after the completion of maintenance. The engine-supporting structure supports a rear upper mounting portion of an engine, on left and right pivot plates, by providing left and right upper engine-supporting frame portions at central areas of the respective pivot plates. interposing a left upper collar between a left upper engine-supporting frame portion and a rear upper mounting portion formed on an engine, interposing a right upper collar between the right upper engine-supporting frame portion and the rear upper mounting portion formed on the engine, and coupling the left and right upper engine-supporting frame portions, the left and right upper collars, and the rear upper mounting portion by a rod-shaped member.
