Right Justin! As of now I've had to dismantle the horns to fit the fairing.
It is quite an interesting exercise, fitting the fairing, given the rather small tolerances, but after loosening a few screws, repositioning the brace, and using a measured amount of force I succeeded without braking, scratching, or bending anything to get all the parts in their proper place.
Tomorrow will be the big day, when the screen get into place and the rubber bellows on the forks will be fitted. If I am lucky the brake hose and the choker control cable will arrive tomorrow as well, and then it is riding time!
If I get the time, I will write an RS-fairing fitting manual for the wiki.
greetings from a sunny north with good riding conditions
