Why Your 2025 Ducati Multistrada V4 May Be Burning More Fuel Than It Used To

Shop parts for a 2025 Ducati Multistrada V4 Motorcycle.

Your 2025 Multistrada V4 carries the 1,158cc V4 Granturismo engine: a liquid-cooled four-stroke with electronic fuel injection, ride-by-wire throttle control, and a fully electronic ignition, sending power through a chain final drive. That configuration shapes everything below. There is no choke to leave on, no float bowl to stick, and no ignition points to wear. When a bike like this starts drinking noticeably more fuel, the explanation usually lives in one of three places: how and where you are riding it, how freely it rolls and breathes, or a sensor or mechanical fault that has pushed the fueling away from where it belonged.

Riders notice the problem in two different ways. Some track every fill-up and see the numbers slip. Others simply realize they are pulling into fuel stops more often than they used to. Both observations point at the same short list of possibilities, and neither one is automatically a sign of something serious.

Confirm the Change Before Chasing It

A single tank proves nothing. Fuel economy on an adventure-touring bike swings with temperature, load, wind, and route, so you need three or four consistent fill-ups before a trend means anything. Fill the tank to the same level each time, note the odometer or reset a trip meter, ride normally, then refill and divide the distance covered by the fuel you added. Keep the receipts or notes and compare like trips to like trips.

One easy way to fool yourself: a speedometer and odometer that no longer read true. Because this bike is chain-driven, a sprocket change alters the relationship between engine speed and road speed, and a different rear tire size or profile does the same thing. If the odometer is under-reporting distance, your calculated economy looks worse than reality even though nothing about the engine has changed.

Riding Conditions and Habits Cost Real Fuel

Cold weather is a frequent culprit. The engine takes longer to reach its efficient operating range, and the fuel itself can change seasonally, with winter and ethanol-blended blends delivering less energy per volume than what you burn in summer. Add a headwind, and the aerodynamic load climbs quickly with speed — which is why long stretches at sustained highway pace hurt far more than the same distance of mixed riding. Carrying a passenger and loaded luggage adds mass to accelerate and a larger frontal area to push through the air.

Your right hand matters just as much. Repeated hard acceleration away from stops, holding a gear or two lower than necessary so the V4 sits high in the revs, and selecting a sharper ride mode all raise consumption. Long idling warm-ups waste fuel too — and this engine already deactivates its rear cylinder bank at a standstill specifically to cut fuel use and heat, so sitting still for minutes works directly against that design. Short trips that end before the engine is fully warm are the least efficient miles you will ever ride.

Rolling Resistance, Brakes, and the Chain

Start with tire pressure, checked cold against the spec for your load. Underinflation is the single most common and cheapest cause of a quiet economy decline, and it also wears the tires faster. Next, check for a dragging brake caliper. After a ride where you did not use the brakes hard, carefully feel each rotor; one that is noticeably hotter than the others, or a bike that is hard to push around, points to a caliper that is not fully releasing. On a chain-driven machine like the Multistrada V4, the chain itself deserves attention: a dry, rusty, or overtightened chain soaks up power and loads the drivetrain, and a worn chain and sprocket set does the same. Clean, lubricated, correctly adjusted, and properly tensioned is the goal.

Air Filter, Spark Plugs, and Combustion Quality

An engine only makes useful power from the air and fuel it can actually burn. A clogged or heavily dusted air filter — easy to pick up on gravel and dirt roads — restricts airflow and throws off the mixture. Spark plugs that are worn, fouled, or gapped incorrectly can fail to ignite the charge cleanly, so some of the fuel leaves without doing work. Because your bike uses electronic ignition, there are no contact points to wear or timing to drift, but the plugs themselves are still a maintenance item and a reasonable thing to inspect when economy drops.

Fueling and Sensor Faults on This Injection System

Modern fuel injection relies on sensor feedback, and a sensor reading incorrectly can push the mixture rich without any obvious symptom at first. The oxygen sensors in the exhaust are what the engine control unit uses to fine-tune fueling in closed-loop operation; a slow, contaminated, or failing sensor can bias the mixture richer than needed. A coolant or engine temperature sensor that reports the engine as colder than it truly is tells the ECU to add fuel, much like a choke would on an older machine.

A leaking or dirty injector can deliver more fuel than commanded or spray poorly. On a multi-cylinder engine like this V4, throttle bodies that are out of sync can cause rough running and uneven fueling. Stored fault codes may be present even if no warning light reached the dash, and a fuel leak anywhere in the system — a damp fitting, a seeping connection, or a persistent fuel smell — wastes fuel directly.

Engine Condition, Cooling, and Modifications

Low compression from general engine wear, poorly sealing valves, or worn rings reduces how efficiently the engine converts fuel into forward motion, and no amount of tuning will recover it. Because this bike is liquid-cooled, a thermostat stuck open lets the engine run below its intended operating temperature, which keeps the ECU in an enrichment mindset. Modifications belong here as well: an aftermarket exhaust or high-flow air filter installed without a matching calibration changes airflow in ways the stock fueling map was never written for, and the result is often a richer, thirstier running condition than the bike had when it was stock.

When to Hand It to a Mechanic

Some symptoms justify skipping further guesswork. A strong, persistent fuel smell, black or unusually dark exhaust smoke, spark plugs that come out sooty, a dashboard warning light if your bike has one, or rough running that appeared alongside the mileage drop all point toward a fueling or sensor problem best diagnosed with proper equipment. The same is true if you have addressed tire pressure, the chain, the air filter, and your riding patterns, and consumption is still high. At that stage, describing what you have observed — when the drop started, how the bike behaves when cold versus warm, and what you have already checked — gives a technician far more to work with than a simple complaint about fuel economy.
