To change the look of my Yamaha MT-09, I bought the "Gullwing" windscreen of DPM. It's made of aluminium and is mounted to the already existing mounting points of the MT-09.
This windscreen has only visual purpose. I didn't notice a difference in wind protection after mounting it to my bike.
The windscreen is mounted firm to the bike and does not wobble while riding.
Note: This windscreen doesn't come with a Vehicle Type Approval.
For mounting the 4 screws in the head of the Yamaha MT-09 are used. 2 metal holder are fastened to the bike and the windscreen is mounted to them with the delivered screws.
The looks of the own motorcycle is determined by each user differently. I made some comparison images so that you can see the change in looks, if you mount a DPM Gullwing windscreen to your MT-09.
