That is a good reason why the computer is on my bars and not hers. I have a governer built into the bike. When RR starts squeaking, I can only go about 5 mph faster then I better start exercising the dual disc brakes. I always remember that my back is exposed but she won't do anything during the descent. She will wait for a slow moment and then there will be remediation. The fastest we have ever been is 49 mph and that was on a long straight run with no curves.
