.. welcome to DSC.
Service intervals on the models you're looking at are annual or every 6,000 miles, whichever comes first. Belts should be changed at two years or 12,000 miles if in warranty or every year if out - a form of insurance really. The annual service is important because engine oil and brake fluid deteriorate with age, seals dry out and tyres flat-spot if left sitting in the one position. As said before best to buy with full history. Apart from that just let the engine tick over when first starting from cold to allow the oil to reach the rockers. Be warned - Ducatis become a passion
