Hi,
In response to all the good ideas and speculation here, I must say that I am excited. Triumph has not only not minded using several names for similar bikes - they don't mind changing names either. I do wish they'd keep the 790 engine.
It is a great intermediate size and a good starter size for some. I want my wife and daughter to ride a Triumph. Neither of them are experienced riders, and all Triumph has to offer is a 600cc bike with 48 more horsepower than mine.
That is not a beginner bike. Not only would I like to see the America become an upper midweight, I'd like to see Triumph revive the 500cc twin, or even a single. I have thought about buying a Royal Enfield for my girls to learn on, but the Rebel250, GZ250 and Virago250 are all too enticing. When they outgrow one of those in 3 months, where do they go? Triumph has got to expand to lesser sizes also.
Keep the America as it is, that's fine. Call them what you will, that's fine. Just get some variety through all sizes.
I know the 250 single wasn't real successful for Triumph or BSA, but the 500 twin was a great size for beginners - ask Fonzi!
Ride Safe,
Dennis
