yes you are right ,you will show more Km than you have really done
I use this method to give me a reasonably accurate estimate of my actual speed , I work out what the bike will pull in top gear at 1k RPM for a stock busa with a sprocket combo of 17/40 and a stock wheel /tyre these are the calculated kph for each 1k rpm for
1st =12 kph at redline 125 kph
2nd = 16 kph 169
3rd = 20 kph 215
4th = 24 kph 255
5th = 27 kph 288
6th = 30 kph 314
so check your speed at these RPM
60 kph = 2000 rpm
80 kph = 2700 rpm
100 kph = 3400 rpm
110 kph = 3700 rpm
from the above figures my own bike runs between 12% to 15+ % optimistic with the higher the speed the greater the error
