From what i saw in your video, you can gain more top speed if you install a double bubble screen without holes like the one i have, Fabbri Double Bubble screen, or if you want to keep your original screen, try to cover the holes with a strong tape, according to a UK bike magazine test, you should gain around 5 km/h more!!

I'm glad that you have liked the clip although I did not formed correctly my GoPro. Also I surprised the speed difference, because the wind that existed was side and not straight ahead, it can be that in the minutes that passed there has been some change in his direction ó intensity. I do not like walking in the route without mirrors because here there are motorbikes very fast and it is necessary to be with attention, but this day angered me that the motorbike was not spending 307 km/h and that's why I folded them because the previous weekend the motorbike it ran 319 km/h with the mirrors, a pity that was starting raining and I had to flee
Very interesting the test with the bubble without holes.
My bike has putting a ZG Racing and the bike improved in speed, but I did not bear in mind that thing about the holes. Checking the catalogue of BMW S 1000RR I found the following thing on his pages 28/29:
...... ' And above this is the windshield, incorporating two holes on either side to air reduces turbulence around the rider s head. '
Clearly the holes are for comfort of the pilot and not thinking about the maximum yield.
My next tests will be:
1- Transmission 520. Until there does not come to me the chain EK ZZZ, I do not want to change because here, several have broken 520 of other marks. If the motorbike improves, as they say, I will keep on extracting him teeth to the rear sprocket, because I want more speed but not to overcome 13.900 rpm.
2- To lower the motorbike and principally to diminish the distance between the front wheel and the fender, I do not want to make one more surrounding (models like Hayabusa ó ZX-14), because I believe that they do uglier to the bike, but it is necessary because with our fenders we must lose penetration.
3- Of course to cover the holes of the bubble and to prove if the turbulency does not make me see double, that was happening to me with a ZG DB in my anteriror R1, which was slower. Thank you very much for the advice.
