Both scooters are power by same 109.51cc engine and deliver similar power performance so you may expect a similar fuel efficiency too. With its sharp styling, the Honda Dio remains a popular scooter among the youth. The new addition of features has increased its appeal further, while the new cycle parts make it a better scooter to ride than before. However, it is an expensive offering for a 110cc scooter. On the other hand, the new list of updates on India’s most popular scooter have made the Activa 6G a more exciting proposition than before. However, the Activa 6G still misses out on some basic features which should have been standard by now. You may compare both the scooters according to their variants too. Do take a test ride in order to clear your all doubts. Check out authorised dealership details.
