Abstract

An exhaust system for a motorcycle, that can improve external appearance saleability by inhibiting generation of flow noise without worsening external appearance, is provided with a tail cap 53h, a ring shaped outer cap 60 that is fixed to a rear end edge 52g of a casing 52, and an inner cap 61 that is fixed to a rear end wall 52a of the casing 52 and that has a tail hole 61c having a size that allows a tail pipe 51 to pass through it with a gap there between. A gap s is formed in a boundary region between the inner cap 61 and the outer cap 60.
