Am using activa since 2011 and it had not faced any serious problem related to its engine an all its handling and cantrol is very smooth and its pick up is all very good but the thing which disappointed me is its fuel consumption in add they say it will run more than 60km in 1 liter petrol but actual petrol consumption is 35-40 km in 1 liter petrol which is ok I have no issue with it look because it look is very good and it is very comfortable .
