Q. What is the reserve tank capacity of ktm duke 250?

Fuel injected motorcycles does not have a fuel reserve mechanism. The low fuel warning will turn on after the fuel level go below 1.4 litres. However, unlike most other motorcycles (e.g., I think the last 1.5 to 2 litres of fuel in Dominar will not be used by the fuel injection system), Duke 250 does not have any unusable reserve. Meaning, most of the fuel within the tank can be used up by the rider.
