Greybeard:
"The Bonneville America name went away in '03 instead of '04. It officially went away when the '03 model year began, but it unofficially went away after they used up the '02 side covers a month or two after '03 production began."

2004 unofficial:
Bonneville America name starts its phase out from Bonneville America to "America"

2005
Speedmaster gets the 865cc engine


The 2007 model year for the Americas and Speedmasters flipped the aesthetics, i.,e. they swapped looks. With hindsight, this model year was the second to the last step towards EFI. All that was lacking chassis-wise was the fuel tank.

* Adjustable clutch and front brake levers
* Black engine with chromed covers

Speedmaster gets:
*New cast wheels
