Why Your 2015 Ducati Multistrada 1200 Is Using More Fuel Than It Should

The 2015 Ducati Multistrada 1200 is a liquid-cooled, fuel-injected, chain-driven four-stroke V-twin with fully electronic ignition and ride-by-wire throttle. That configuration shapes everything below: there is no carburetor to flood, no choke to stick, and no ignition points to drift, so the plausible causes are sensor, calibration, and mechanical-wear related. It is also a large, powerful adventure-touring machine that was never designed to sip fuel, so the real question is whether consumption has changed from what this bike normally delivers for you.
Confirm the Drop Is Real Before Chasing It
Many riders spot the problem as range rather than as a number: the same familiar commute suddenly needs an extra fuel stop. To quantify it, fill the tank to a repeatable level, reset the trip meter or record the odometer, ride normally through the tank, then refill to the same level and divide the distance covered by the fuel added. One tank proves very little, so repeat the process across three or four tanks before concluding anything.
It is also worth ruling out an odometer error, because a non-stock rear tire size or a change in sprocket sizes alters how far the bike travels per wheel revolution. When the odometer under-reports distance, your fuel economy math looks worse than reality, and the range estimate shown on the dash is off for exactly the same reason.
Weather, Fuel Blends, and How You Ride
Cold weather, winter-blend fuel, and ethanol blends all trim efficiency a little, and so do headwinds, sustained high-speed highway running, a passenger, and loaded luggage. The Multistrada is tall with a lot of frontal area, so aerodynamic drag climbs quickly as speed rises. Riding habits matter just as much: hard acceleration, holding lower gears longer, and long idle warm-ups all burn fuel for very little distance.
Ride modes change the picture too, since a sharper throttle map invites bigger throttle openings for the same pace. If consumption fell off right after a change in route, season, or load, that may be the whole explanation.
Rolling Resistance and Drivetrain Drag
Underinflated tires are among the most common causes riders overlook, and they are free to check — set pressures cold with a reliable gauge. A dragging front brake caliper, from sticking pistons or swollen seals, forces the engine to fight the brakes constantly, and a disc that feels unusually hot after a ride with little braking is a clue.
Because the Multistrada is chain driven, the chain deserves a look as well: a dry, rusty, or overtightened chain adds real drag and loads the countershaft bearing. Clean and lubricate it, set slack correctly, and check the sprockets for hooked or worn teeth at the same time.
Airflow, Spark, and Combustion Quality
A clogged air filter restricts airflow, and the fuel injection responds by adding fuel for the same throttle opening. Spark plugs that are worn, fouled, or gapped incorrectly cause partial misfires and incomplete combustion, and fuel that does not burn cleanly is fuel wasted. This bike’s ignition is fully electronic, so there are no breaker points to wear or drift out of adjustment, but a weak coil, cracked plug cap, or damaged plug can still degrade combustion. A slight roughness or hesitation you have learned to live with is often the earliest sign of one of these.
Fuel Injection: Sensors, Injectors, and Throttle Bodies
The Multistrada relies on oxygen sensors in the exhaust to trim mixture during normal running, and a slow or contaminated sensor can bias fueling rich in a way that quietly erodes economy. An engine or coolant temperature sensor that reads colder than the engine actually is keeps the system in enrichment longer, which often shows up as a fast idle along with heavier consumption.
Dirty or leaking injectors deliver more fuel than the ECU intends, or spray it in a pattern that burns poorly. With a throttle body for each cylinder, dirty or poorly synchronized throttle plates hurt idle quality and part-throttle efficiency. Stored fault codes can exist without an obvious warning light, and any fuel smell, staining, or wet fitting around the tank and lines should be corrected immediately.
Compression, Cooling, and Valve Condition
Low compression from worn rings or poor valve sealing reduces efficiency everywhere in the rev range, not just at full throttle. On this Desmodromic V-twin, valves that have drifted out of adjustment can cost both power and economy, which is why keeping up with service matters. Because the engine is liquid cooled, a thermostat stuck open is also worth considering: an engine that never reaches full operating temperature runs richer for longer. That penalty is most obvious on short trips, where the bike may never warm fully before you shut it off.
Modifications That Change Fueling
An aftermarket exhaust or a high-flow air filter fitted without matching calibration is a classic reason for a sudden drop in economy. The ECU adapts within limits, but a free-flowing intake and exhaust running on stock fueling often ends up rich in places, and the cost shows up at the pump. If consumption changed the same week a bolt-on part went on, that is your most likely answer — either return the part to stock or have the fueling corrected properly.
When to Involve a Mechanic
Bring the bike in if you notice a strong fuel smell, black sooty exhaust, spark plugs that come out black and coated, a warning light on the dash, or rough running, misfiring, or hesitation alongside the mileage drop. The same applies if economy stays poor after tires, chain, filter, plugs, and riding conditions have all been ruled out.
When you describe the issue, include when it started, whether it is consistent, and anything the dash has displayed. A shop can read stored codes, watch live sensor data, check compression, and clean and balance the throttle bodies far more efficiently than replacing parts on suspicion.
