The TVS Radeon 110 has a claimed mileage of 69.3 kmpl with 11.5 liters of fuel capacity. This will give you roughly 780 kilometers of range on a full tank, including the reserve capacity. On the other hand, the Hero Splendor has a mileage of 65 kmpl and a fuel capacity of 11 liters. This will give you a range of roughly 700 kilometers. However, the mileage of the Radeon is still on paper and is not according to the road and city conditions. However, the mileage of the Hero Splendor is tried and tested. If you have the mileage in mind, the Splendor will always be the better option of the two.
