Why Your 2019 Ducati Multistrada 1260 S Is Using More Fuel Than It Should
Shop parts for a 2019 Ducati Multistrada 1260 S Motorcycle.The 2019 Ducati Multistrada 1260 S is a liquid-cooled, fuel-injected, chain-driven four-stroke V-twin, and that specific combination dictates which causes of poor fuel economy are actually worth chasing. There is no carburetor to leave a choke partly engaged, and no ignition points to drift out of adjustment, so the realistic suspects on this bike live in the electronic fuel and spark management, the intake tract, the drivetrain, and the way the machine is being ridden. If a tank no longer carries you as far as it once did, work through the following from free and simple checks toward deeper mechanical ones.
Start by Confirming the Drop Is Real
Before assuming a component has failed, measure properly. Fill the tank to a consistent level, reset the trip meter or note the odometer, ride normally, then refuel at the same pump to roughly the same level and divide the distance covered by the fuel you added. A single tank proves very little, because one windy day or an extra passenger can skew the result. Track three or four consecutive tanks before drawing conclusions.
It also helps to know that changes to rear tire size or to final drive gearing will alter how far the odometer believes you have traveled, which can make economy look worse than it truly is. If a sprocket was recently changed or a different size tire fitted, that alone may account for the change you are seeing.
Riding Conditions and Habits That Quietly Cost Fuel
Not every drop in economy is a fault. Cold weather increases warm-up enrichment, and ethanol-blended or winter-blend fuel returns slightly less energy for the same volume. Sustained high-speed highway running, strong headwinds, a passenger, and loaded panniers all raise the workload on the engine. Short trips that never let the engine reach full operating temperature are especially costly, because the injection system deliberately runs richer while the engine is cold. Long idling warm-ups before pulling away do the same thing.
Riding style matters just as much. The Multistrada 1260 S offers selectable ride modes, and a bike left permanently in its sharpest, most aggressive setting delivers quicker throttle response and consumes more fuel than the same machine in a gentler mode. If most of your recent riding fits one of these patterns, the change may simply reflect how the bike is being used rather than anything broken.
Rolling Resistance, Brakes, and the Chain
Underinflated tires are the most common and most overlooked cause of a gradual economy decline. Check pressures when the tires are cold and set them for the load you are actually carrying. A brake caliper that drags — often from sticky pistons or aged fluid — adds constant resistance the engine must overcome. After a ride, feel near the discs for unusual heat concentrated on one side.
This motorcycle is chain driven, so the chain deserves attention as well. A dry, rusty, or over-tightened chain robs power and fuel in equal measure. Set the slack to the correct specification, keep the chain clean, and lubricate it regularly. A seized link or a hooked sprocket can cause the same drag even when the adjustment looks right.
Air Filter and Spark Plugs
A clogged or heavily contaminated air filter restricts airflow, and the fuel injection system compensates in ways that hurt economy. If the filter has not been serviced in a long while, or if you ride in dusty conditions, that is an inexpensive place to start.
Worn, fouled, or incorrectly gapped spark plugs cause incomplete combustion, meaning less useful work from each drop of fuel. Pull them and look: a heavily sooted appearance points toward a rich mixture rather than a worn ignition component. On this bike the ignition is fully electronic and its timing is not adjustable by the owner, so timing drift is not a realistic diagnosis. Plugs, coils, and their connections are the more probable culprits when spark quality is in question.
Fuel Injection, Sensors, and Stored Fault Codes
The 1260 S uses closed-loop fuel injection with oxygen sensors, so sensor health has a direct effect on consumption. A slow, contaminated, or failing oxygen sensor can bias the mixture rich. A coolant temperature or intake air temperature sensor that reads colder than reality tells the engine management system the engine still needs enrichment, and it responds by adding fuel.
Injectors are another common source of trouble. A dirty injector sprays poorly, while a leaking one delivers more fuel than intended. On this V-twin, throttle bodies that fall out of balance cause uneven running that can also cost fuel. Fuel leaks at hoses, connections, or injector seals are easy to overlook and waste fuel directly — a strong fuel smell in the garage after a ride deserves prompt attention.
The management system also stores fault codes when it detects a problem. A dealer can read those codes even if no warning light ever appeared on the dash, which makes a diagnostic scan a sensible early step rather than a last resort.
Engine Condition, Cooling, and Modifications
Low compression from worn rings or sealing problems reduces efficiency, so the engine needs more throttle for the same speed. On this bike, valve clearance is a scheduled service item, and clearances that have drifted out of specification can affect how well the engine breathes and burns.
Because the Multistrada 1260 S is liquid-cooled, a thermostat stuck open keeps the engine below its intended operating temperature, and the engine management system continues enriching in response. That is a specific, checkable cause rather than a general one.
Modifications deserve a mention too. An aftermarket exhaust or high-flow air filter installed without matching fueling correction is a frequent cause of a rich-running condition and reduced economy. On a bike like this, the correct mapping or reflash is part of doing that job properly.
When to Involve a Mechanic
Some symptoms point beyond routine maintenance: a persistent raw fuel smell, black smoke from the exhaust, spark plugs that come out heavily sooted, rough or uneven running alongside the mileage drop, or a dashboard warning light if your bike displays one. The same applies to a drop that survives fresh plugs, a clean filter, correct tire pressures, and a properly adjusted chain.
At that point, a diagnostic session where fuel trims, sensor readings, and stored codes can be examined directly is far more productive than replacing parts on suspicion. Bring notes on when the change began, what conditions you ride in, and anything recently changed on the bike — that context shortens the path to an answer considerably.
