One thing that I noticed looking at the Scramblers at the Seattle motorcycle show is that there is small tank/canister on the Icon that isn't on the Urban Enduro. I didn't notice it until someone pointed it out later, so I didn't check for it on the other models.
On the Icon, it is on the left side, just forward of the engine. You can see it just to the left of "Ducati" in the Icon picture below. It looks like some kind of emissions part, so I wouldn't expect it to be model-specific.
Anyone know what it is and why it isn't on the Urban Enduro?
