Thor- those bars (and barends) are standard on the new model Mercbike. They are swept forward to extend the reach. You can rotate them any way you want though.
spambait11- it can't really shift nor would I want it to in this instance. The lower one will float a little but the middle idler sprocket need to track closely to the rear sprocket's chainline. All I did was grind a little spacer that shims the sprocket over. In my case after shipping it appeared to be too much. So I took off about 0.7mm to move it just a bit.
