I've had several bikes with a wet clutch. They all worked fine and quiet. In my search for a Ducati I see there are wet and dry clutch bikes over the years. I'm interested in a used bike by they way. In the past, when I wasn't really interested in owing a Ducati, I have heard Ducati bikes pulling up to a spot at the side of road making lots of noise and I always assumed it to be from the dry clutch. My question is do the bikes come from the factory without a noise barrier/cover over the clutch or are they removed or modified for effect? Also is there any benefit to one over the other?
