Of course, it now looks nothing like the bike on which it's based - more like what Harley might have produced if it got into road racing a couple decades ago.
In a video featuring the creation, Icon says the custom Sportster is "600 pounds of antiquated mechanics uncorked to maximum velocity with only guile and cunning to keep her in check" and it's "the most beautiful and ugly thing we've ever built." We have to agree. See Iron Lung for yourself in the first video below, and then head further down to watch Everything is Process, in which you'll find out the driving force behind Icon's custom bikes and see Iron Lung in the build process. Enjoy!
