I bought honda cativa 4g with 109cc engine and its overall performance is good.but the main problems in honda activa scooters is there suspension system.unlike motorbikes.the suspensions of both the wheels of activa are very hard.even at small pits.it gives great shock to that person mostly who is sitting at the back.thats why at the time of second service of my activa, I ask the serviceman to do something for the suspension.he says that there is a liquid in suspension system which is responsible for the bouncing of suspension.he says he is not able to modify it.but thats ok.it is bearable.
