I guess I get second place, I turned 19 last September.
Bought my zuki GS450 the spring after I turned 16, rode that for like 2 months then got bored with it, and bought the Magna that summer. Rode that until about halfway through this past summer when I upgraded to the Max.
Crotch rockets never appealed to me. Too uncomfortable, and the insurance would have been insane. Plus, I'd rather cruise than be able to go 160mph at the drop of a hat. Which doesn't mean I don't like to go fast, so that's how I settled on the Max as a good balance. Posture and (almost) cruiser comfort(at least for me at only 5'8"), yet it's the fastest "cruiser" around. Gotta love that feeling that doing 70 is effortless for the engine, and you're only at 1/8th throttle, and 100+ is only about a sec or two away.
