lower performance in gears

The speeds you report all come in at 5500rpm.
That's pretty accurate point to reach top speed per gear, so that sounds like you are hitting a limiter.

Are you getting these speed readings from the speedometer or a GPS device?
What specification rear tyre are you running?

Assuming speedo readings; given your bike's modifications I would point first at the accuracy of the speedo. You can use an app on your phone to get accurate speed, and verify speedometer circuit accuracy.

After that - have you got tuneboy or tune ecu?
Hook it up and see what your rev limit is set to.
And while you're there, check speedo calibration adjustment (assuming you read your speeds from the speedo and not a GPS)

Also on my 2010 Roadster 6500rpm in 2nd is about 80mph, not 87. The other 2 speeds you give correspond however.

sorry but now, unluckily, I don't know accurately.. it has been with tuneEcu, some years ago, by authorize service dealer.. doubtless however so, not less 5900 rpm but not more 6150 rpm.. speed insteaad checked with GPS too, for rear tyre while I opted for Bridgestone Exedra Max

Make surre that you don't have the restricted Euro- tune, I think it is for France, that limits the power to some amazingly low number.
