Which looks more fun? a Dual-Sport:

(supermotard: 80% asphalt, 20% dirt, motorcross bike, radial tire with some dirt capability)

video... ump calls "Safe!" (you can't do THAT on a crotch rocket)

Or a serious street bike?

Or just a moped? (with NOS, of course!)

stoppies with sandals! (dude's nuts)

Or an 800pound GoldWing:

(yeah yeah, I'll never do 90% of what a bike (or moped) can do. But as long as you have a camera that can catch people doing stupider things than you'll do, then it's all good)
