A storage box 15 is arranged from above the main tube 2 to above the front part of the seat rail 5, and a tandem-shaped seat 16 that also serves as a pillion seat is placed on the seat rail 5 behind it.

Due to the presence of the storage box 15, the fuel tank 17 is installed in a space surrounded by the seat rail 5 and the body tube 6 below the seat 16.

Both sides from the front of the engine unit 7 under the storage box 15 are covered with a cowling 18, and continuously below the lower edge of the seat 16 and both sides of the fuel tank 17 are covered with body covers 19.

The storage box 15 is connected to this upper main tube 2a.
and following the shape of the seat rail 6, viewed from above,
It has an almost oval profile with a round front end and a narrow rear end, and when viewed from the side, the lower edge of the front half follows the upper main tube 2a, and the rear wall 20 slopes rearward and downward so as to be parallel to this.
It takes on the shape of a parallelogram.

This storage box 15 has a bottom (bottom plate 21), has a volume that can store a full-face helmet 22, and has an opening 23 on the top surface through which it can be taken in and taken out. A lid 25 whose front end can be opened and closed forward and upward by a hinge mechanism 24 is attached to the opening 23 . Further, the lid 25 is locked by a locking mechanism 26 in the closed position.

The lower surface of the rear end of the storage box 15 is pivotally supported via a hinge mechanism 28 on a base plate 27 spanning the left and right seat rails 5 so as to be able to swing rearward and upward, and the lower surface of the front end is supported by a cushion.
