If it's an '06 it's most likely a Tourer. These actually were an '07 only model although I'd imagine a number would have been '06 build. The a Tourer was really just a Classic with screen, panniers, backrest/rack (and silver engines) - done as a run-out to shift the silver engines I bet. Triumph did the same thing (screen, bags, backrest) in '09 with Standards to shift them before the Roadster came along.
The Touring is a different beast altogether with single headlight, gauges on the tank, hard bags and narrower (and smaller) rear wheel. They were first released in '08.
Not that any of this matters, except for when you might be seeking help with something and it's important to know which model you have.
