where to buy a touring screen ??

True. KTM also makes one. The Skidmarx one is like a slightly longer version of the OEM screen (with the same bend at the top). I've got it and it makes some difference in wind blast without, IMO, being too ugly. KTM's screen is substantially longer and presumably stops lots more wind but, IMO, easily clears the ugly hurdle.

better than stock for sure, but don't let the word "touring" fool you...
