## Abstract

A motorcycle prevents an increase in air resistance and prevents wind and mud from hitting a rider during travelling of the motorcycle. A side cover of the motorcycle includes a first side cover and a second side cover. The first side cover is disposed laterally outwards of a head pipe and a front fork. The second side cover is disposed laterally outwards of a portion of the first side cover. A lateral end of the second side cover is positioned laterally outwards of the first side cover. A rear edge of the first side cover is at least partially positioned rearwards of a rear edge of the second side cover.

## Claims
