Also in my opinion the flyscreen does help a lot to for the wind to flow above your helmet in a tucked in position, before the screen install I can really feel the wind pressure on the face of my helmet at high speed and it’s pretty much gone after the screen is installed.
@aitomartin just checkout aliexpress and search for ktm mirrors and you will see number of sellers selling similar type. I bought a “Fenrir” branded one from a more expensive seller but I don’t think it makes a difference, seller probably get them all from the same supplier.
Just find the cheapest one and quality will be the same. I would have prefer a non branded one for $12 from this seller
if there’s a problem just take pictures and open a dispute and aliexpress will refund you.
