An intake system for a vehicle engine includes an air cleaner and a plurality of throttle bodies. The air cleaner encases an air cleaner element in an air cleaner housing for filtering air flowing from an unfiltered air chamber to a filtered air chamber of the air cleaner housing. The throttle bodies control the amount of air supplied from the filtered air chamber to a cylinder head. Operating noise of the throttle bodies is minimized by situating the throttle bodies within the air cleaner housing. Operating noise of fuel injectors associated with the throttle bodies is minimized by situating the fuel injectors within the air cleaner housing.

An air cleaner housing includes an upper case, a partition wall and a lower case. The inside thereof is partitioned into an upper, filtered side and a lower unfiltered side. Intake funnel pipes, connected to front and rear cylinders, project into the filtered side. An air cleaner element is provided on the front side relative to a hollow plenum above the intake funnel pipes. Inlets in side surfaces of the unfiltered side face toward a V bank of the engine. During use, air enters the bottom of the housing, and is cleaned by the air cleaner element. The clean air flows through the filtered side of the housing, into the intake funnel pipes and toward the cylinders on the lower side. A raised portion is formed on the front upper side of the upper case, and the air cleaner element is disposed inside the raised portion.

A motorcycle body frame includes a main frame including a head pipe for supporting a front suspension at the front end thereof, a single leading frame portion extending rearwardly from the head pipe, and a rear frame portion for supporting a rear wheel suspension. The rear frame portion extends substantially downwardly from a rear part of the leading frame portion. The main frame, cast from an aluminum alloy, includes two component parts arranged front-to-rear. For example, a front frame portion is provided, and a rear frame portion is fixed to the rear side of the front frame portion. The leading frame portion has a small section portion, where the main frame is smallest in sectional area, disposed substantially centrally in the longitudinal direction thereof. The two component parts of the frame are joined at a coupling portion of the main frame situated in back of the small section portion.

A rear cushion unit has an upper end mounted on a swing arm and a lower end coupled to pivot brackets in a position below a pivot shaft. The pivot brackets are independent of each other and are not coupled to each other. With the above construction, a fuel tank, electric parts, or other parts, for example, can be clustered between the left and right brackets. Accordingly, the parts can be disposed near the center of gravity of the vehicle body. Therefore, the maneuvering capability of racing and off-road vehicles incorporating such an arrangement can be increased. The vehicle frame can be simplified in structure and can be manufactured at a reduced cost. When the vehicle is assembled, the distance that the worker needs to move can be reduced, and hence the productivity of the vehicle is increased. The size of the vehicle is reduced because of the clustered arrangement of the parts.

To operate a pillion step in one action. The pillion step is formed in a generally L shape and includes an arm portion and a foot rest portion. One end of the arm portion is pivotably secured through an oblique pivot shaft to a side face of a seat rail located under a rider seat and is pivotally moved around the oblique pivot shaft. When the pillion step is to be retracted and is pivotally moved backward, the foot rest portion moves into a gap between the rider seat and a pillion seat and its tip end is received within a grip space formed in a grip.

A saddle-riding type vehicle includes a vehicle body, a pivot frame that supports a swing arm for rear wheel suspension, and a rear master cylinder disposed rearwardly of the pivot frame. A reservoir tank supplies hydraulic fluid to the rear master cylinder, and the reservoir tank is disposed between the pivot frame and the rear master cylinder. A portion of the swing arm, adjacent to the reservoir tank, is configured with a concave recess formed therein extending inwardly towards a longitudinal center line of the vehicle body. The reservoir tank is situated closer to a vehicle body inner side, and is deeper in the recess than the rear master cylinder.
