Winston Yeh and his team at Rough Crafts are making it look easy, having won the 2013 AMD World Championship in their first attempt. The winning custom Harley-Davidson Sportster — dubbed the Stealth Bullet — is shown off here in a series of beauty shots that highlight its sleek monochrome aesthetic. The low-slung bike is outfitted with a handful of upgraded parts that include a custom headlight and seat, fitted on a minimalist girder suspension that rides on a 21-inch Performance Machine wheel in the front and 18 inch wheel in the back. A custom swingarm, rocker and cam covers round out the details. Check out additional images below.
