The Dirtbag Challenge is a San Francisco favorite among the motorcycling community. You may have seen a chopper build off or two, but nothing quite like this.
Although the website doesn't include details for 2012, the general rules are the same; $1,000 budget, no Harleys (*gasp*), 1 month build time and must be rideable (100 miles the day of, in fact).
It's a unique showcase of creative and cool motorcycle minds coming together to worship motorcycles and do loads of burnouts. It wouldn't be a motorcycle event without burnouts, right? Here are some pics I obtained from a few friends and a link to Glen Coddington's photo album on UrbanMoto.
