Abstract

The invention relates to a secondary air supplying device for a motorcycle to facilitate the maintenance of an air cleaner for a secondary air, to eliminate the necessity of mounting an excess component to connect a suction tube to a frame pipe, and to reduce a cost, in which the part of a passage for supplying the secondary air to an exhaust system of an engine mounted in a body frame having the frame pipe having the frame pipe is formed in the frame pipe. The downstream end of the suction tube 64 is connected to the suction port of the air cleaner 3 for the secondary air supported to the body frame 25 disposed at the outside of the frame 25, and the upstream side of the tube 64 is inserted into the end opening of the frame pipe 30 by interposing a soundproof material 65 between the tube 64 and the inner surface of the pipe 30.

Description

technical field [0001] The present invention relates to a secondary air supply device of a two-wheeled motor vehicle, in which a part of a passage for supplying secondary air to an exhaust system of an engine is formed in a frame pipe. Background technique [0002] Such a secondary air supply device is disclosed, for example, in Japanese Patent Application Publication No. 3-32742, and is formed by using the inside of the frame pipe, which is difficult for dust to enter, as a part of the passage for supplying the secondary air. [0003] However, in the above-mentioned prior art, since the air filter for secondary air is installed in the frame tube, the maintenance of the air filter for secondary air is very difficult, and since the air filter installed in the frame tube is used The structure in which the hoses are connected to the connection pipes on the side walls requires the work of installing the connection pipes to the frame pipes, and thus costs will increase accordingl...
