Description

The present invention relates to a straddle-type vehicle.

There are straddle-type vehicles in which a steering wheel and a front cover are integrally rotated. For example, in the straddle-type vehicle disclosed in Patent Document 1, the front cover is supported by the front forks. When the rider turns the steering wheel left and right, the front cover rotates together with the front fork.

JP 2007-126126 A

In the straddle-type vehicle described above, a footrest is arranged behind and below the front cover. A gap is provided between the front cover and the footrest to prevent the front cover from interfering with the footrest when the front cover rotates together with the front fork. However, this gap makes it easy for muddy water splashed up during riding to adhere to the rider's feet.

In addition, the rotation of the front cover tends to collide with objects around the vehicle. Even if the front cover is damaged as a result, it is not easy to repair the front cover. Furthermore, if the front cover is enlarged in order to prevent splashing of muddy water, the front cover is more likely to be scratched.

Moreover, if the front cover becomes heavy due to the enlargement of the front cover, the operability of the steering deteriorates. SUMMARY OF THE INVENTION It is an object of the present invention to provide a saddle-riding device that suppresses interference due to rotation of the front cover, suppresses deterioration in steering operability, suppresses splashing of muddy water onto the rider's feet, and facilitates repair of the damaged front cover. To provide a model vehicle.

A straddle-type vehicle according to one aspect of the present invention includes a head pipe, a seat, a footrest, a steering device, front wheels, and a front cover. The seat is arranged behind the head pipe. The footrest is arranged in front of and below the seat. The steering device is rotatably supported by the head pipe. The front wheels are rotatably supported by the steering device. The front cover covers the head pipe. The front cover is attached to the steering device. The front cover rotates together with the steering device.

The steering device includes a steering shaft, an under bracket, and a front suspension. The steering shaft is rotatably supported by the head pipe. The under bracket is connected to the steering shaft. The front suspension includes an inner tube and an outer tube. The inner tube is connected to the under bracket. The outer tube rotatably supports the front wheel.

The front cover includes a central cover portion, side cover portions, and side protectors. The center cover portion overlaps the head pipe when viewed from the front of the vehicle. The side cover portions are arranged laterally of the central cover portion. The side protector is separate from the side cover portion. The side protector is attached to the side cover portion.

The side protector is detachably attached to the side cover portion. The side protector is arranged with a gap between it and the side cover portion. As viewed from the side of the vehicle, the side protector is arranged in front of the footrest. The side protector extends below the under bracket.

In the straddle-type vehicle according to this aspect, the side protectors that are separate from the side cover portions are attached to the side cover portions. Therefore, by reducing the size of the side cover portion, interference due to the rotation of the front cover can be suppressed. In addition, even if the gap between the side cover portion and the footrest becomes large due to the downsizing of the side cover portion, the side protectors extend greatly downward, thereby suppressing splashing of muddy water.

Furthermore, since the side protector is detachable, it is easy to replace the side protector even if it is damaged. Therefore, it is easy to repair the damaged front cover. Also, the side protector is arranged with a gap between it and the side cover portion. As a result, an increase in the weight of the front cover is suppressed, and deterioration in steering operability is suppressed.

The upper end of the side protector may be positioned above the seat. In this case, the high position of the side cover portion is protected by the side protector. The lower end of the side protector may be positioned below the side cover portion. In this case, the side protector protects the lower portion of the side cover portion.

As viewed from the side of the vehicle, the side protector may extend from above the head pipe to below the upper end of the outer tube along the axial direction of the front suspension. In this case, the large side protector protects a wide area of the side cover portion.

The side protector may overlap at least a portion of the front suspension when viewed from the side of the vehicle. In this case, the side protector protects the front suspension. The side protectors may include cutouts. In this case, the weight of the side protector is reduced.

The side protector may include a first fixing portion and a second fixing portion. The first fixing portion may be positioned above the notch. The first fixing portion may be fixed to the side cover portion. The second fixing portion may be positioned below the notch. The second fixing portion may be fixed to the side cover portion. In this case, the reduction in strength of the side protector due to the notch can be suppressed.

The side protectors may be made of a stronger material than the front cover. In this case, the strength of the side protector is improved. The side protectors may be made of transparent or translucent material. In this case, scratches on the side protector are less noticeable.

The straddle-type vehicle may further include flashers. The flashers may be arranged above the side protectors as viewed from the side of the vehicle. In this case, even if the side protector is enlarged, the visibility of the flasher is ensured.

As viewed from the side of the vehicle, the flashers may be arranged along the upper edge of the side cover portion. The front cover may further include a lid. The lid portion may be attached to the upper edge of the side cover portion. The lid may cover the flasher from above. In this case, mounting of the flasher is facilitated.

According to the present invention, in a straddle-type vehicle, interference due to rotation of the front cover is suppressed, deterioration of steering operability is suppressed, and splashing of muddy water to the rider's feet is suppressed, and damage to the rider's feet is prevented. It becomes easy to repair the front cover.
