Company History
Under the Viper name, several American ventures pursued muscular customs and performance cruisers with billet-heavy construction and big-inch V-twins. Emphasis fell on straight-line authority and premium finishes, with chassis geometry kept rideable for highway use. As with many boutique projects, dealer coverage and certification costs limited scale, but the bikes demonstrated how American style can intersect with modern components—strong brakes, fuel injection, and quality suspension—to produce machines that look dramatic yet function as real transport.
