If it makes you feel better to think they are like the old bikes you may delude yourself all you want but when you look it simply isn't so. Internally they are even farther but I think we are talking style. They even sound different.
I feel I need to add Speedmaster and America are beautifully styled bikes and are distinctly NEW Triumph and I like them very much or I wouldn't be riding one.

I learned all I need to know about life by killing smart people and eating their brains.
