I have owned 11 motorcycles, one of which was a Ducati 1200 MTS Touring.
Ducati's are great bikes, but they are not as reliable as Japanese bikes and maintenance and parts are crazy expensive.
For example, the Multistrada 15,000 mile service is about $1200. Main parts replaced are the timing belt and spark plugs. I think the spark plugs are like $50 each (OEM Denso's from the dealer). The newer 1200's (1198) have 2 spark plugs per cylinder. $200 for spark plugs is insane.
Having said all that, the sound of a 10,000+ RPM Ducati is worth the cost if you have the money to blow.
