Why Your 2020 Ducati Multistrada 1260 S May Be Using More Fuel Than It Should

The 2020 Ducati Multistrada 1260 S is a liquid-cooled, fuel-injected, four-stroke L-twin with chain final drive and electronic ignition. It is a modern, high-performance adventure-touring machine, and when it starts using noticeably more fuel than you are used to, the cause is usually one of a handful of things. This article is not a step-by-step repair guide. Instead, it explains the likely reasons your Multistrada 1260 S may be getting fewer miles out of a tank, so you can decide what to check yourself and what to describe to a mechanic.
First, Make Sure the Change Is Real
Before chasing a mechanical problem, confirm that your fuel economy has actually changed. The most reliable method is tank-to-tank calculation. Fill the tank to a consistent level, reset your trip meter or note the odometer, ride normally for the full tank, then refill to the same level. Divide the miles ridden by the fuel added. A single tank is not enough to judge because fill level, temperature, and riding conditions vary. Average several tanks before drawing conclusions.
Also consider whether anything has changed the accuracy of your speedometer or odometer. A different tire size or profile can alter the effective final drive ratio, and on a chain-driven bike like the Multistrada 1260 S, changing sprocket sizes does the same. If the odometer is now reading low, your calculated fuel economy will look worse than it really is. If you have made either change, account for that before assuming the engine is at fault.
Riding Conditions and Habits That Increase Fuel Use
Many fuel economy complaints trace back to how and where the bike is ridden rather than a failed component. Cold weather increases warm-up enrichment and denser air requires more fuel. Winter-blend or ethanol-blended fuel can also reduce energy content. Headwinds, sustained highway speeds, and riding with a passenger or loaded luggage all increase drag and weight, so the engine works harder. Aggressive throttle use, short trips that never let the engine reach full operating temperature, and long idling warm-ups are common culprits. The Multistrada 1260 S has a large, powerful engine, and its fuel use is very sensitive to these factors. If your riding has shifted toward more city traffic, colder mornings, or heavier loads, that alone can explain a noticeable drop.
Rolling Resistance and Mechanical Drag
Underinflated tires are one of the most common and easiest-to-fix causes of poor fuel economy. Check tire pressures when the tires are cold and adjust them to the specification for your load. A dragging brake caliper can also cost fuel. After a ride, carefully feel the brake rotors; if one is much hotter than the others, that caliper may be sticking. The bike may also be harder to push. Because the Multistrada 1260 S is chain-driven, the final drive deserves attention. A dry, rusty, or overtightened chain robs power and forces the engine to work harder. Check chain slack and lubrication regularly. A chain that is too tight can also stress the output bearing, but even a simple lack of lubrication adds drag.
Air Intake, Spark, and Combustion Health
An engine needs the right mix of air, fuel, and spark. A dirty or clogged air filter restricts airflow, which can richen the mixture and waste fuel. This is especially relevant on an adventure-touring bike that may see dusty conditions. Worn, fouled, or improperly gapped spark plugs cause incomplete combustion, so some of the fuel you paid for does not produce power. The Multistrada 1260 S uses electronic ignition, so there are no contact breaker points to wear or adjust, but spark plugs still wear over time. If the plugs are due for replacement or show heavy deposits, that can contribute to both rough running and higher fuel consumption.
Fuel Delivery and Sensor Issues on a Fuel-Injected Multistrada
Because your Multistrada 1260 S is fuel-injected, the old carburetor-related causes – a sticking choke, a misadjusted float, or gummed-up jets – do not apply. Instead, the fuel injection system relies on sensors and electronic control. A failing oxygen sensor can send incorrect feedback to the ECU, causing it to command a richer mixture than necessary. A faulty engine or coolant temperature sensor can tell the system the engine is colder than it really is, which adds fuel. A leaking or dirty fuel injector can drip fuel or spray poorly, reducing efficiency. On this L-twin, the throttle bodies can also fall out of synchronization, which affects low-speed fueling and idle quality. Stored fault codes may be present even if no warning light is on, and a fuel leak anywhere in the system will obviously waste fuel and create a safety concern.
Engine Condition, Cooling, and Modifications
Low compression from general engine wear reduces efficiency, meaning more fuel is needed for the same amount of power. Because the Multistrada 1260 S is liquid-cooled, a thermostat stuck open can keep the engine from reaching full operating temperature. The ECU may then add fuel as if the engine were still warming up, hurting fuel economy. Modifications are another common factor. An aftermarket exhaust or high-flow air filter installed without matching fuel injection tuning can leave the engine running rich. If you added either and did not have the ECU recalibrated or a fuel management device installed, that mismatch could be the reason your fuel economy dropped.
When It Is Time to See a Mechanic
Some symptoms point to a deeper issue that is best diagnosed with professional tools. A strong fuel smell, black exhaust smoke, sooty spark plugs, or a dashboard warning light (if equipped) all suggest the engine is running rich or misfiring. Rough running alongside the mileage drop is another red flag. If you have checked tire pressure, chain condition, air filter, and spark plugs, and the problem persists, a mechanic can read fault codes, watch live sensor data, test injector flow, and check compression. Describe when you first noticed the change, whether it came on suddenly or gradually, and any recent modifications or maintenance. That information helps narrow down the cause quickly.
Fuel economy on a 2020 Ducati Multistrada 1260 S is never a single fixed number. It depends on how you ride, where you ride, and the condition of the bike. Start with the simple, free checks, then work toward the more involved systems. In many cases, the answer is a combination of riding conditions and basic maintenance rather than a major failure.
