I don't know about Ducati reliability first hand, but I recall reading an article in Cycle World (or one of those) and they took a ST3 and ST4 for a cross country ride. I recall them talking about stuff breaking on the trip and they were new bikes. I also recall that while a friend of mine met up with a guy with a new ducati 998 (I think). Anyways, he had problems and they had to push start him every time they stopped. Also I have heard of very high prices when it comes to having the dealership do work on your bike.
I worked at a Ducati dealer of several years.
So what does it cost to have a dealership check the valve clearances? Or how about a tune up?
I saw the same article, and in it they mentioned that the rest of the staff joked that they must be off their rocker, doing a Ducati road trip without a chase truck.
I have also heard electrical problems are an issue with them.
They are sexy, handle very well, not as fast as Jap sport bikes, a small fortune to fix, and at least where I live, a very limited supply of dealers to choose from. Oh yes, and you better check insurance rates, as where I live, they share the same insurance dilema as BMW, due to very expensive parts if you happen to drop one. And also, the salesman at my local dealership tells me they really don't hold up to depreciation any better than a Suzuki.
It's like comparing a Ferrari to a Toyota I figure, Both will get you from point A to point B, only one will do it with practibility, the other with style (and grief)
I just did never see the reason to spend huge dollars on a bike that at the end of the day, will not do things any better than lets say a Suzuki.
