Helmed by metallurgically-talented Winston Yeh, Taiwan based Rough Crafts, has taken a 2009 Harley-Davidson Sportster Iron 883 and turned it into the Iron Guerilla project, something truly inspiring. The Iron Guerilla ($TBA) is a Harley amplified with a mix of muscular upgrades including Coker tires, and a custom Rough Crafts exhaust. The resulting masterpiece is meaty and manly to say the least.
