Hey, even I can see the simularities... it's part of the reason that the America started in the retro range.
The cynic in me says that Triumph did a very clever thing by making them look like the older bikes. They appeal to those who are beyond the days of wrenching or have no idea how to wrench, but like the look of the older.
