Common problem to most motorcycles here, 7% error on an FJR. A little up or down on that for other bikes. Compensation for what kind of tire you might install one day? A bit much overcompensation IMHO......
A car tire will fix you up and get really close, maybe 1% error. A 190/55 rear tire will get you more like 5%. Mostly fergedaboudit, read the speed on your GPS instead, it's not perfect but darn near.
If you want to spend money, get a SpeedoHealer, you can vary the algorithm to get near perfect. I don't recommend that on a Gen3, since you have to buy two of them, one for the front and one for the rear... can mess up the cruise engagement or restrict it (as we found out on a buddy's 2016). Save yer money for a GPS.
Keep yer stick on the ice....
