A great innovation to facilitate the filling of petrol into the tank moped.
Typically, moped riders who face this problem are those who put in the basket quite large, causing the seat can not be opened fully. This causes the seat would tend to fall back on.
The use of universal seat damper also will enable the seat will always remain open and facilitates filling petrol and also perhaps for other things.
Suitable for Honda RS150, LC135, Y15ZR etc..
