I guess I'm one of the lucky few. '13 White 1199 with about 4000 miles, 5 track days (so far this season) and have been caught out in the pouring rain a few times with no issues.
I do thoroughly check the bike often, do some of the maintenance myself and have found no leaks and nothing has fallen off... yet lol
The only problem I had was when I bought it brand new and had the hot start issue (charcoal canister) but that was an easy fix and starts up fine every time now.
I also disagree about this bike only being a head turner. Yes, it definitely does turn a lot of heads, but it also has a lot of character & does really well at the track (though I do favor my old '13 Triumph Daytona 675 for track use)
Anyways, I do strongly agree that Ducati is the one responsible for having every single bolt/nut tight before shipping. I also do not think the dealerships are necessarily the one to blame when such things happen. Yes, they are supposed to check that all the electronics are working as they should during the PDI process and I would assume they make sure the axle nuts, triple, brakes, etc are all torqued, but it is not their job to disassemble the whole bike and retighten everything that the factory should have already done.
My opinion comes from the fact that I am a ASE Master Certified Technician for Lexus and I have PDI'd plenty of cars and also have had plenty of cars come back with little things wrong here and there. There has been plenty of cars come back with oil leaks within a 100 miles and I've had to drop engines just to fix them. It's not my fault that this has happened, it's the factory. They're the ones that should have made sure that the front timing cover should have been properly torqued before shipping. These cars have maybe one or two miles on them by the time it gets to us so you know they're not driving them nearly enough before shipping them out to dealerships. It's not necessarily that the quality has gone down, it's that they're having to produce more of these cars/motorycycles in a shorter amount of time to meet the demand. And it's not just Lexus, it's happening in all makes for automobiles/motorcycles, anything really.
