Well, if they go liquid-cooled... that makes fins obsolete. So, they either get kept as un-needed lipstick, or they get lost and turn the bike into a modern CX500.
Guzzi *isn't* a modern bike. That IS it's appeal. I hate to say it, but it absolutely, 100% IS a heritage company. That's what they're about. I think Piaggio gets it, and I think that's the direction they're taking it. Let Aprilia fill the go-fast/ look-fast market. Let Guzzi sell bikes to dudes that like shaky, simple machines.
I like shaky, simply machines.
