The Hardknock Story:
     Introduced in 2006 as a kit for bike builders, it was an instant hit not only with fabricators, painters and customizers, but with people who just wanted to build their own motorcycle. Through the years the kit was refined, the list of factory options grew, and the frame was enlarged and improved to accept ever larger engines. Although it was a huge success, as a kit bike, it was only street legal in the few states where builders were allowed to assemble their own motorcycle. As of this year, the Hardknock street legal motorcycle with both DOT/EPA approval in the United States and EC-Type approval in all European countries and Switzerland.

  New HK-III vs. Old HK-I

Many of the pictures you see here and on the internet are of the older, smaller kit version of the Hardknock. Although builders loved it,  they wanted 3 main improvements. First, they wanted a frame that was larger and could accept a 250cc engine, such as the Virago v-twin or the Rebel parallel twin. Second, they wanted a bike that came with a title and was 100% street legal. Lastly, they wanted more bolt-on options providing customization without fabrication. We listened to our customers, and the result is the HK-III Hardknock with DOT/EPA approval in the United States as well as European type-approval. What still remains for builders are the endless customizing possibilities, from tanks, handlebars, wheels to even the engine itself.
