mmmmmmmmm,
For me I love the Ducati 4v V twin engine. In fact I have ridden quite a few of the recent V Twins on the market and liked em all.
Never ridden a V4 though. I expect something like an RC30 or RC45 is pretty awsome.

I imagine a Ducati V4 would be quite a serious bit of kit as well. Just cant get over what it would sound like with some open cans on it, hopefully a bit like the GP bike.
