Cool? No. In the same way that wearing pants down around your arse isn't cool. In the same way that being a Chav isn't cool. In the way that modifying the body, wheels, and exhaust on an otherwise bone-stock Honda isn't cool. In the way that any other male attempt to over-compensate for a perceived "shortage" in the package department is not cool.
Visible? Yes. Dorky as hell? Yes. It's the bike equivalent of wearing a day-glo safety vest when you ride.
