KTM 1390 Super Duke R mileage and running cost

1390 Super Duke R's claimed mileage is 16.9 kmpl, and unusually, owners and our own riding land right on it: expect 17–24 kmpl in everyday use. Few bikes get this close to their brochure figure.

Among the 67 sports bikes we have reviewed it ranks last for mileage, 25 kmpl below the group average of 42 kmpl.

At Delhi's petrol price of ₹94.80 a litre and a real-world 20.5 kmpl, the 1390 Super Duke R costs about ₹4.62 per km in fuel. Ride 30 km a day and that is roughly ₹3,607 a month, or ₹43,284 a year, before servicing.

The 17.5-litre tank gives a realistic range of about 359 km, so a 30 km commute means a fill-up every 2 weeks.

Spread over five years and 46,800 km, the 1390 Super Duke R works out to about ₹62.1 per km all-in, of which 7% is fuel and 87% is the purchase price itself. Resale value is not counted; expect roughly 50–60% of ex-showroom after five years for a well-kept example.

The quickest wins for the 1390 Super Duke R: keep tyres at the recommended pressure (under-inflation by 5 psi can cost 2–3 kmpl), shift up early, use Eco mode in traffic and avoid idling at long signals.

Short trips hurt most. A cold engine on a 2 km run can return half its normal mileage; if that is your use, expect the low end of the real-world band.

Service on time. A clogged air filter or old spark plug shows up in mileage before it shows up anywhere else.
