flow of the exhaust gas by the exhaust valve can be reduced with the result that a smooth flow of the exhaust gas can be ensured and the discharge efficiency is enhanced fig9 shows the arrangement relationship of the exhaust pipe and the exhaust valve of the exhaust control apparatus of the motorcycle according to the present invention the exhaust control apparatus 11 ensures a smooth flow of the exhaust gas and the exhaust efficiency is improved by providing the exhaust valve 12 which controls the flow rate of the exhaust gas within the exhaust collection pipe 33 and by arranging the valve rod shaft 62 of the exhaust valve 12 at a position away from the centers c 1 c 2 of the plurality of exhaust pipes first and second pipes 31 32 as a result the ability to control the exhaust gas using the exhaust control apparatus is enhanced in fig9 reference numeral 61 indicates a valve of the exhaust valve 12 which is mounted on the valve rod shaft 62 the exhaust control apparatus 11 should be understood such that when the number the plurality of exhaust pipes is set to two the valve rod shaft 62 of the exhaust valve 12 can be inclined or tilted within a range of e 1 to e 2 35 to 55 degrees with respect to the straight line l 1 which connects the centers of two exhaust pipes first pipe and second pipe 31 32 that is the exhaust control apparatus 11 is formed such that when the number of the plurality of exhaust pipes is set to two the valve rod shaft 62 of the exhaust valve 12 is inclined within a range of e 1 to e 2 35 to 55 degrees with respect.
