post a picture of your bike and we can tell you what model year it falls into, no problem.There are a good few discriminating factors between 05-06 and 07-onwards. 2010 I believe they made some very small changes, but i'm damned if I can remember and I'm pretty sure they were internal - so you'd never spot it by looking alone.
as I'm flying to Brazil in a few hours, I probably won't see if you do post up a pic, so very quickly, the differences I'd be looking for to see if your bike was 05-06 or 07-on;
Headlight mask - easy one, that.
Speedo - again, very easy - 05-06 is the two piece orange backed affair, analogue tacho, wheras 07-on is an all-digital one piece
^^^ the above are often changed, so can fool people...
Radial brakes on the 07-on
Bigger tank and slightly different tank spoilers on 07-on
Different "super duke" font on tank spoilers
^^^ not many people change this so this is the first thing I'd look for
Black swingarm on mid/late 08-onwards
and, umm, those are the biggies.
I'm talking standard SD here, not SDR by the way
