Q. What is the reserve fuel capacity of Apache RTR 180?

Contrary to what TVS claims i have found that 9 to 10 litres fills up the tank almost up to the cap ( including about 1.75 litres in reserve.) Its never a good idea to fill more. The correct way to measure your mileage is to let it come to reserve, note the km. reading, fill whatever quantity you want, and finally note the km reading exactly when the next reserve comes up. This will give you your correct mileage if you divide the kms by the litres you have filled.

12 litters tank and you must keep 2 litter fuel in your bike always if its less then 2 litters and you drive it will destroy you fuel kit and which not have any guraanty

In general, 10-12 percent of the overall fuel capacity is the reserved capacity of the vehicle. The TVS Apache RTR 180 features a 12 liters fuel tank and the reserved fuel capacity would be around 1.2- 1.4 liters.
