We got our honda activa in Oct 2013 and so far it travelled 11000+km. While it runs smooth on road there are some big issues with honda activa.
1) It has higher maintenance cost during each servicing
2) front suspension is old age technology and gives no comfort at all
3) no pass switch and no trip meter given.
4) if you are not using it for 3-4 days, you have to kick for many times to make it start and switch start will hardly work
5) quality of mirror is not good it loosens up withing 1-2 months after each servicing
6) fuel efficiency has never been more than 50 kmpl in city.
