2021 Ducati Monster 0.9L Petrol · OV21 UHE

The 937cc Monster typically returns fuel economy in the mid-40s to low-50s mpg depending on riding style, with annual fuel costs of roughly £400-£600 for low-mileage leisure use. Road tax for a Euro 5 petrol motorcycle of this capacity is modest, usually around £100 per year. Insurance for a naked sports middleweight sits in the middle groups, so expect £250-£450 annually depending on the rider's profile and history.

Servicing costs are higher than for a Japanese equivalent, with Ducati specialist labour rates typically £70-£100 per hour. Major services including valve clearances and timing belts are required at 18,000-mile intervals and can run £500-£800. Tyres for the 937 Monster are mid-priced, with a set of quality rubber around £200-£280 fitted. Overall annual running costs for a low-mileage owner are likely £800-£1,100.

The MOT history identifies a leaking fuel system component as a failure point, so carefully inspect the fuel lines, injector seals, and quick-connect fittings for any signs of weeping or staining. Although the retest passed, fuel leaks can recur if the underlying seal or hose was not properly replaced. Check under the tank area for residual fuel smell or discolouration on the frame.

The headlamp aim failure is worth a close look. Verify the headlamp mounting bracket is not cracked or bent, as a misaligned beam can result from a loose or damaged mount after a minor drop or vibration over time. Check both low and high beam alignment against a flat wall. Also examine the headlamp connectors and wiring for corrosion.

General Ducati Monster 937 inspection points include the rear subframe bolts (a known inspection item on this generation), the single-sided swingarm pivot, the radially-mounted front brake calipers for seized pistons, and the quickshifter operation if fitted. Check the chain and sprockets for wear, and confirm the date codes on the tyres to ensure they are not aged out despite low mileage.
