A vehicle includes an upper frame, a lower frame, a front frame, a rear frame, a pair of rear wheels, a drive motor to drive the pair of rear wheels, a battery supported by the upper frame and the lower frame to supply electric power to the drive motor, a straddled seat at a higher position than the drive motor, and a bar handle at a higher position than the straddled seat. The battery includes a battery lower portion and a battery upper portion. The battery upper portion includes a projection that overhangs in at least a horizontal direction with respect to the battery lower portion. At least a portion of the drive motor is below or directly below the projection.

Vehicle

A vehicle, including: a pair of front wheels; a pair of rear wheels; a saddle-style seat, positioned at an intermediate region in a width direction of the vehicle; a steering shaft provided ahead of the seat; a bar handle connected with an upper portion of the steering shaft, the bar handle having a pair of grips; a front fender provided above the pair of front wheels, striding over the pair of front wheels in a plan view of the vehicle; and a pair of suspensions, top ends of which are located ahead of the two grips, and are positioned, in the plan view of the vehicle, more inboard than widthwise ends of the two grips in the width direction of the vehicle. Each suspension includes, at an upper portion thereof, a suspension adjusting portion. The front fender includes a pair of openings through which the suspension adjusting portions are accessible.

A vehicle includes a front differential, a pair of constant-velocity joints, and a steering mechanism. The steering mechanism includes a pitman arm, a pair of tie rods, a pair of first link arms each connecting the pitman arm with a corresponding one of the pair of tie rods, and a pair of second link arms each connecting a corresponding one of the pair of first link arms with a body frame. In a plan view, at least a portion of each constant-velocity joint is located between first and second straight lines extending in a fore-aft direction and through first and second connectors extending between the tie rods and the first link arms. The first connector, the second connector, and at least a portion of each constant-velocity joint are located between third and fourth straight lines extending between the first and second link arms.

An upper arm projected line Lis defined as a straight line formed by projecting an upper arm line Lonto the projection line P. a lower arm projected line Lis defined as a straight line formed by projecting the lower arm line Lonto the projection line P. An intersection point Pxbetween the upper arm projected line Land the lower arm projected line Lis located in a region Adefined higher than the horizontal plane Pand defined farther outward in the right-left direction than the skiThe suspension enables turning performance of the straddle-type vehicle to be improved.
