My brother is into sports bikes, not sure what he's riding these days.
My dad has one of these for long trips and...
Something like this for cruising.
I've only ever fucked around with little 125 dirtbikes myself.
My dad and brother are basically just into anything with an engine. They've both got shelves full of trophies from stock car racing. Pretty cool. And yes, I am the loser of the family.
Edit: Oh, and a few of my cousins were into motorcross.
