Hi Paragon,
The Adventure screen remains exactly the same dimensions as standard. It may look like it is pushed out from the pics but this isn't the case. In order to handle the extra width of the Adv screen over the stock screen, the triangular Tobinator "spreaders" are used to make the Adv screen fit properly. It may be these spreaders which make you think the screen is pushed out wider, but this isn't the case.
The Adv Tobinator kit does away with the large plastic screen mounts which come with the Adv bike. Instead, screen mounts from the standard 1150GS are used which are narrower than the Adv mounts, then the Tobinator risers are fitted to those, then the Tobiantor spreaders are fitted to the risers. All in all, the width of that setup is exactly the same as the original Adv mounts.
Hope this answers the question.
Cheers
Tobers
