I have said this before and you are all wrong. The name of the 2 up Bobber will be Bobberett.
If you look on the Triumph web page they have made the Bonneville a class of motorcycles instead of a single bike.
I have been on the Bobber a couple times and even though it looks small it is a peppy thing.

On both the 900 and 1200 the specs do not look great, but they did a good job with the power band in the engines.
I also agree with the statement of when is engine size big enough. I would not give up my 2005 America for nothing. I love the bike and I love the 790cc engine and being able to play with it.
I did get a Rocket 3 Touring in the spring and I will say it is a much better interstate bike than the America. The America is still more fun to ride.
