The documented failure patterns on used Ducati Monsters — the mileage window where each shows up,
and what the repair typically costs at an independent shop. This is the same data NoLemon's Brief checks
against every VIN.
Desmodromic valves need checking about every 6,000-7,500 miles on the air-cooled twins, and cam belts must be replaced roughly every two years — skipping either can wreck the engine. Ask for receipts showing the last valve service and the belt date. No records means budgeting a full service the day you buy.
BEFORE YOU BUY Ask for repair records covering this item. If it hasn't been addressed and the
car is in or near the mileage window, price the $500–$1,000 repair into your offer — or make it the seller's problem.

Dry clutch wear (plates and basket)
Older dry-clutch Monsters rattle loudly at idle — that part is normal — but the plates and basket wear fast in city riding. Feel for slip under hard roll-on in a tall gear and for grabby, shuddering engagement from a stop. It is a routine wear item on these bikes; price it into the deal rather than walking away.

Plastic fuel tank swells and deforms
The nylon fuel tank swells with ethanol gas until it jams against the frame and can leak; a US class action forced Ducati to extend tank warranties on these years. Sight down the tank for bulges and check that the tank still lines up with the seat and side panels. That extended warranty is long expired, so a bad tank is now the buyer's problem.
