The cushion unit is pivotally attached to the rear end of the arm, and the cushion unit is connected between the rear part of the power unit and the upper rear part of the frame. The lower end of the cushion unit and the arm tip of the upper front part of the power unit are connected by two link bars and a swing arm. This is because the front part of the power unit is pressed downward when is contracted.

A rubber bush is also inserted between the arm and the shaft attachment portion at the front lower end of the power unit. And when the cushion unit shrinks,
Since the front portion of the power unit is pressed downward by the two link bars and the swing arm, the cushion rubber and the rubber bush can be bent downward, and the amount of upward movement of the power unit can be reduced. This makes it possible to reduce the gap between the upper side of the power unit and the frame.

It is possible to reduce the amount of upward movement of the front portion of the power unit by bending the cushion rubber and the rubber bush to which the front lower end of the power unit is attached to be deformed downward.
As a result, the gap between the upper side of the power unit and the frame can be reduced, the height of the seat can be lowered to facilitate riding, and the storage space under the seat can be increased. Also, the cushion rubber and rubber bush reduce the transmission of engine vibration of the power unit to the frame. Especially, the engine has the largest vibration when idling at low speed, and the cushion rubber and rubber bush flex when the cushion unit is compressed. Even if it is deformed, it has almost no effect on vibration reduction.
