So. Does the "one bike does all" holy grail exist? What would your pick be?

Bubbler..I watched that as my dad got older. In his youth he rode Indians, then Harleys. As he got older he got rid of the heavy Harleys and dropped down to a 350 Yamaha, a 350 Honda 4, then dropped down to a CB200, then a CB 175 and I believe his last and smallest bike was a Ducati 125 single. I think dad was in his mid 70s at that point. I always wondered if I would follow the same path. My older brother (he's 75) still rides a Sportster having dropped down from a Goldwing. At 64 in May I am still riding the heavy bikes, the ST 1300 and my " little" CB 1100, and my younger brother (62) has dropped down from Goldwings to a FZ 1000 and a Triumph Bonneville.

I too have no interest in riding a trike at this point, but could see myself riding a Yamaha 250-400 scooter.
