Contacted Madstad about an adjustable screen for the XTZ and they were very keen but as they don't have the bike in the U.S. They needed measurements etc to make one up. Never got around to it.

I like the idea as a fixed screen has a few problems in my opinion.
1 make it big enough to provide good wind protection and now it's a hazard offroad, very likely to put it through your face in an off or simply standing up.

2 the wind dam effect produces the buffeting we experience and accentuates the airflow up through the tank/fork area. If the screen was off the bike at the front the airflow under the screen would neutralise the buffeting from the fork area.

3 being able to lift the screen or at least play with the height and angle should enable any size people to find their sweet spot that stops the buffeting on the helmet. Even more important for keeping the minister of war-and-finance on the pillion happy.

So to that end I would still be interested in one as the make the support that the screen mounts to and reinforcing the headlight mount assembly would also fix a weak point on the bike for me. Then the larger selection of adjustable screens should suit any rider.
Worth shooting them an email and seeing if they are interested still, might be a good solution. They may do a universal kit that is just the windscreen of your choice and the Robo-brackets that could be mounted to a cut down screen.
