An inner fender includes a cover surface, a left projecting portion, and a right projecting portion. Under a condition that a body frame is in an upright state and that a left front wheel and a right front wheel are not turned, the left projecting portion projects forward from the cover surface behind a rear edge of the left front wheel; the right projecting portion projects forward from the cover surface behind a rear edge of the right front wheel; and a portion of the cover surface between the left projecting portion and the right projecting portion faces a space defined between the left front wheel and the right front wheel.

Vehicle

A left front fender includes a left upper wall portion, a left side wall portion, and a left guide portion. The left upper wall portion defines a left upper inner surface facing a portion of an upper surface of a left front wheel. The left side wall portion extends downward from the left upper inner surface to define a left side inner surface facing a left side surface of the left front wheel. The left guide portion defines a left guide surface extending rightward from the left side inner surface toward the left side surface of the left front wheel.

An excessive torque restricting mechanism restricts a magnitude of a torque which is to be transmitted from a steering shaft to a connecting mechanism including a tie rod, a magnitude of a torque which is to be transmitted from a left shock absorbing mechanism to the connecting mechanism, and a magnitude of a torque which is to be transmitted from a right shock absorbing mechanism to the connecting mechanism.

A vehicle prevents interference of a right lamp and a left lamp with a link mechanism without increasing the size of the vehicle in its width direction. A right link side portion of a right lamp is located on the right of a locus along which a link mechanism extends when an upper cross portion turns when looking at the vehicle from the front of an upper middle axis. At least a portion of the right link side portion is located on the left of a right end portion of a body cover, above the upper middle axis, and below an upper end portion of the link mechanism that results when the upper cross portion turns clockwise to a maximum extent relative to a body frame, when looking at the vehicle from the front of the upper middle axis.

A vehicle includes a center transmission plate, a first center turnable portion configured to turn about a first center turning axis extending in an up-down direction, a second center turnable portion configured to turn about a second center turning axis extending in a front-rear direction, a left transmission plate, a first left turnable portion configured to turn about a first left turning axis extending in the up-down direction, a second left turnable portion configured to turn about a second left turning axis extending in the front-rear direction, a right transmission plate, a first right turnable portion configured to turn about a first right turning axis extending in the up-down direction, and a second right turnable portion configured to turn about a second right turning axis extending in the front-rear direction. A tie rod is supported on the second center turnable portion, the second left turnable portion, and the second right turnable portion.

A right front fender and a left front fender are displaceable relative to a vehicle body frame in accordance with an operation of a link mechanism. At least a portion of the right front fender is disposed above a center in the up-down direction of the vehicle body frame between an upper end of a right front wheel and a lower edge of the link mechanism or a steering mechanism directly above the right front wheel, as seen from a front in the front-rear direction of the vehicle body frame when the vehicle body frame is in the upright state. At least a portion of the left front fender is disposed above a center in the up-down direction of the vehicle body frame between an upper end of a left front wheel and a lower edge of the link mechanism or the steering mechanism directly above the left front wheel, as seen from the front in the front-rear direction of the vehicle body frame when the vehicle body frame is in the upright state.

At least a portion of a tie rod of a steering force transmitting mechanism overlaps with a portion of a first support member or a second support member when viewed from a front of a vehicle in a fully-tilted condition in which the vehicle body frame is fully tilted in the left-right direction. At least a portion of the tie rod is disposed below a second cross member, above a first front wheel and a second front wheel, behind a front end of the first front wheel and a front end of the second front wheel, and ahead of a first axis of a first side member and a second axis of a second side member when viewed from the left or right of the vehicle when the vehicle body frame is in an upright state.

A right front fender and a left front fender are displaceable relative to a vehicle body frame in accordance with an operation of a link mechanism. At least a portion of the right front fender is disposed above a center in the up-down direction between an upper end of a right front wheel and a lower edge of the link mechanism or a steering mechanism directly above the right front wheel, and is disposed below a right lower edge of a front portion of a link cover portion, as seen from a front in the front-rear direction of the vehicle body frame when the vehicle body frame is in the upright state. At least a portion of the left front fender is disposed above a center in the up-down direction between an upper end of a left front wheel and a lower edge of the link mechanism or the steering mechanism directly above the left front wheel, and is disposed below the left lower edge of the front portion of the link cover portion, as seen from the front when the vehicle body frame is in the upright state.

A transformation restricting mechanism is configured to change a resisting force between a first connecting member, a second connecting member, and a caliper that are configured to be displaced relative to each other. The first connecting member includes a turn supporting portion supported by a first shock absorbing device. The second connecting member includes a turn supporting portion supported by a second shock absorbing device. The turn supporting portion is supported by the first shock absorbing device closer to a first center axis than an intermediate axis which is coincident with a turning axis of a steering shaft when the vehicle body frame is in an upright state. The turn supporting portion is supported by the second shock absorbing device closer to a second center axis than the intermediate axis when the vehicle body frame is in an upright state.

A vehicle includes a stop element supported on a first support portion which is provided on any one of a link mechanism, a body frame, a right shock absorbing device, and a left shock absorbing device at a first end portion thereof so as to turn about a support axis of the first support portion, a lock caliper supported on a second support portion which is displaced relative to the first support portion and which is provided on any one of the link mechanism, the body frame, the right shock absorbing device, and the left shock absorbing device and which is configured to change a frictional force with the stop element, and a guide member which guides a middle portion or a second end portion of the extended member to the lock caliper. A turning angle of the stop element relative to the first support portion based on a turning operation of a first cross member and a second cross member relative to the body frame is smaller than a turning angle of the first cross member or a turning angle of the second cross member relative to the body frame based on the turning operation.

Motorcycle

A motor cycle incorporates a sensor detecting a condition of the tire, such as, for example, tire pressure. A transmitter transmits the tire condition and a receiver receives the tire condition. An indicator indicates the tire condition. A battery supplies electric power to an engine of the motorcycle, the receiver and the indicator. A control device controls the power supply to the engine, the receiver and the indicator from the battery. A main switch assembly and an activating switch, which activates the receiver and the indicator, are interposed between the battery and the control device. The control device allows power supply to the engine, the receiver and the indicator when the main switch assembly is turned on. The control device also allows power supply to the receiver and the indicator when the activating switch is turned on. In some arrangements, the activating switch is automatically turned on when another sensor detects a condition change of a frame assembly of the motorcycle.
