Most powerful, um, dunno actually - I don't pay any attention to numbers like that.
Scariest, a little fizzy 50CC thing I once road from one friend's house to anothers for them. I swore then I'm never riding something that small again. I felt so vulnerable, slow, unresponsive and light that those few miles were amongst the worst in my life.
I'm honestly less daunted by a Goldwing that a Scooter.
