Triumph Thruxton 400 mileage and running cost

The Thruxton 400 is rated at 27 kmpl (claimed mileage). Treat that as a ceiling: real-world figures are usually 15–25% lower.

Among the 114 sports bikes we have reviewed it ranks 72th for mileage, 6 kmpl below the group average of 33 kmpl.

At Delhi's petrol price of ₹94.80 a litre and a claimed 27 kmpl, the Thruxton 400 costs about ₹3.51 per km in fuel. Ride 30 km a day and that is roughly ₹2,739 a month, or ₹32,864 a year, before servicing.

Spread over five years and 46,800 km, the Thruxton 400 works out to about ₹11.2 per km all-in, of which 31% is fuel and 60% 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 Thruxton 400: keep tyres at the recommended pressure (under-inflation by 5 psi can cost 2–3 kmpl), shift up early 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.
