Life may begin at 30, but it doesn't get real interesting until about 150.

One hundred fifty miles per hour, that is.

It's true. The feeling of an open road and an open throttle is unmatched. Rocks Off loves motorcycles. At one point, we owned three, until we found our bike of choice: A Suzuki Hayabusa 1300 GSX1300R, arguably the world's fastest sports bike. But don't argue. We'll smoke you on 59 if you try.

And what do we love as much as motorcycles? We love hip-hop equally. In fact, we don't ride our motorcycle unless we're listening to a playlist of our favorite tracks. It makes the experience that much more stimulating.

Recently, over a "sip session" with our cousin, which is a period involving alcoholic beverages, hip-hop discussion and watching the latest rap videos on YouTube, Rocks Off ran across Philadelphia rapper Meek Mill's mutual passion for motorcycles, but his was a bit different than ours.

You see, Meek Mill loves dirt bikes. In an urban setting like Philly, where we can't imagine there are exactly endless piles of dirt to jump, you wonder if there's a disconnect. There isn't.

We first heard about dirt-bike clubs in major cities a handful of years ago from our boy Charlie, who's from the Boogie Down Bronx. He rides bikes, too, and has spoken enthusiastically about dirt-bike clubs throughout the New York boroughs.

The dirt bike scene in Philadelphia is rich. That inspired Rocks Off to count down the five best motorcycle hip-hop videos.

Here we go. Zoom, zoom.
