Improves the performance of your motorcycle and provides an aerodynamic protection adaptable to each moment and situation of your driving thanks to the manual lifting mechanism for your screen (M.E.M.). It is a compact mechanism that allows your to modify the position of the screen of your motorcycle without tools to adapt itself to the different situations that the route demands. You can raise and increase the aerodynamic protection on fast roads or adverse weather conditions, and you can also decrease it in the city or when driving off-road for a wide field view without interference, or of a sport look. You can use the mechanism and place the screen in the position you want with a quick and easy twist on the fixings, and fix it again with just your hands, without the need of tools. The mechanism works for your O.E.M. screen or for Puig screens for your motorcycle.
