If you notice its "Universal Spoiler for fairing windshields" so not really specific to Yager.
I've tried them on other bikes and they can get the air up higher but I think the Yager
needs wider as well as taller.
I tried this as an experiment on my Yager;
It defiantly helped but it felt wrong somehow. There seemed to be a lot of noise, that might have
taken away from the enjoyment some...
