I bought this model honda eterno in 2004, but whole of its engine was one sided which gives average of approx 45-50 km per 1 litre.
Once while driving its rear wheel left its chasis and hardly I was saved from dangerous accident its whole balance goes to right side of the handle and it is very hard to handle it in top speed, its service to is very expensive and most of its parts are not available in market and have to look for alternatives.
Although this model has been discontinued by Honda but still if you are going to buy it a second-hand model of this scooter I will advice that not to go for it, it will cost you a lot. Not only that, the scooter is very heavy also, which creates difficulty in handling. So, I will suggest not to go for it.
