I am an owner of a Hinckley Triumph. To me, it is a British bike. Brakes are Nissin, forks are Showa, ECU is Kiehin. Very few parts on this bike are made by Triumph, or even sourced in the UK or EU. To me, that doesn't make it any less British. Even though Mr. Bloor sources many parts in Thailand and Malaysia, and even has an assembly plant in Thailand, the bikes are Hinckley designs.
Is a Benelli an Italian bike, or a Chinese bike? It now has Chinese ownership, but still has some manufacturing in Italy, and the design is definitely Italian.
In the US, most Ford, GM and Chrysler cars are assembled with parts sourced from around the world, and often the car is assembled in Mexico or Canada. Similarly, Hondas, Toyotas, Nissans, Mazdas, BMWs, Mercedes-Benz, etc. are assembled in the US, often with a large percentage of locally-sourced parts. Does this make an Ohio-built Honda more American than a Mexico-built Ford?
