Abstract
An exhaust control apparatus for a motorcycle includes an exhaust collection pipe, which collects and combines exhaust gas from a plurality of exhaust pipes, and an exhaust valve. The exhaust valve is operatively attached to the collection pipe and controls flow of exhaust gas within the collection pipe. A pivot shaft of the exhaust valve is situated at an angle and is displaced from the centers of the exhaust pipes, such that the shaft is not aligned with the centers of the exhaust pipes. This arrangement of the pivot shaft provides a smooth, non-turbulent flow of exhaust gas, and reduces impedance to the flow of exhaust gas. The exhaust control apparatus may be mounted to reside within a recess formed in a motorcycle body frame, to reduce vehicle width.
