A seat frame for a motorcycle includes a plurality of aluminum parts manufactured with different manufacturing methods. A seat frame includes front members, middle members, and a rear member, the front members, the middle members, and the rear member being formed of aluminum. The rear member is formed by integral molding based on a gravity casting method. The rear member includes a pair of left and right rail portions, a front cross portion, a rear cross portion, and a plurality of attachment bosses for attaching other parts. The left and right rail portions each have an attachment portion to be connected to a rear end portion of corresponding one of the middle members provided on an end portion thereof on the front side in the vehicle longitudinal direction.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame. A secondary storage compartment may be located under the seat. Additionally, the storage compartments may have electronic locking mechanisms that are activated via a wireless connection to a remote electronic device.

A saddle riding vehicle includes a body frame and a cable. The body frame includes a main frame extending rearward from a head pipe, a seat frame extending rearward from the main frame, and a rear frame extending rearward from the main frame and connected to the seat frame. The cable is routed so as to run along the body frame. A concave portion depressed in a vehicle width direction is disposed in a connecting portion. The connecting portion connects the main frame with a front end portion of the rear frame. A plate-shaped member that covers the concave portion is disposed. The cable is routed between the concave portion and the plate-shaped member.

A vehicle includes a plurality of ground-engaging members and a frame supported by the ground-engaging members. The frame includes a front frame member and a rear frame member coupled to the front frame member. The vehicle also includes a powertrain assembly supported by the frame and an air intake assembly operably coupled to the powertrain assembly and the front frame member. The air intake assembly includes at least one air inlet member extending into a portion of the front frame member. The air inlet member extends from an inlet opening to an outlet opening, and a portion of the air inlet member intermediate the inlet and outlet openings has a diameter less than a diameter of the outlet opening.

A vehicle body frame includes a main frame that extends from a head pipe toward the vehicle rear side above an engine and a down-frame that extends downward from one end fixed to the head pipe. The main frame is assembled into a truss shape from a pair of left and right upper frames and a pair of left and right lower frames and reinforcing frames disposed between these upper frames and lower frames. Front end parts of the upper frames are fixed to the upper end side of the head pipe and front end parts of the lower frames are fixed to a part close to the head pipe in the single down-frame.

A motorcycle frame including a left side frame member, a right side frame member, and a steering head member positioned along a longitudinal center plane of the frame between the left and right side frame members. The steering head member includes a steering head portion defining a steering axis. A plurality of fastener joints are established between the steering head member, the left side frame member, and the right side frame member, the plurality of fastener joints positioned rearward of the steering head portion. A fastener joint, separate from the plurality of fastener joints, is established rearward of the plurality of fastener joints between the steering head and the left side frame member. A fastener joint, separate from the plurality of fastener joints, is established rearward of the plurality of fastener joints between the steering head and the right side frame member.

An electric vehicle includes a battery having a housing. The housing includes a rear side which is defined as a side facing away from a forward travelling direction of the electric vehicle. The electric vehicle further includes a frame, a motor having a housing, and a pivot shaft stack-up assembly co-aligned along a pivot shaft axis. The pivot shaft stack-up assembly includes first and second portions of the frame, a swingarm extending therebetween, and an idler bracket. A shock mount is integral with the battery housing. The shock mount extends from the rear side of the battery housing. The battery housing is configured as a stressed chassis member in which each of the motor housing, the frame, and the pivot shaft stack-up assembly are aligned thereof. The shock mount provides a path along which a load is directed to the battery housing.

A vehicle body frame includes a head section that rotatably supports a steering shaft, and main frames extending from the head section toward a rear side of a vehicle body. A cross section of the main frame in a direction crossing a vehicle body forward/rearward direction is formed in a substantially rectangular shape having a vertical width larger than a lateral width. A carbon fiber reinforced resin in which carbon fibers are oriented uniformly in the vehicle body forward/rearward direction is installed on at least one of upper surfaces and lower surfaces of the main frames.
