    • A motorcycle has a head pipe supporting a steering shaft, a pair of bilateral main frame pipes having front ends fixed to the head pipe and extending rearward therefrom, an engine unit disposed below the main frame pipes and having cylinders projecting obliquely forward from an engine casing, an air cleaner covered by an air cleaner casing which is disposed between both the main frame pipes, and intake devices extending upward from the cylinders and having air intake inlet portions inserted into the air cleaner casing. The air cleaner casing has a bottom portion to which a downwardly protruded portion is formed at a rear position of the intake devices, and the main frame pipes are connected through a first coupling member disposed between the intake devices and the protruded portion of the air cleaner casing. The air cleaner casing is formed with a recessed portion at the bottom portion thereof, and the recessed portion has a shape suitable for accommodating the first coupling member. A pair of bilateral head frame pipes are further provided so as to be fixed at the front ends thereof to the head pipe and extending rearward therefrom below the location of the main frame pipes, and second coupling members connecting the first coupling member to each of the head frame pipes are also arranged.
