Changing my exc from 21" to 16.5".

The speedo is set to 2205... Which from the manual is the "circumference of a 21" wheel"... Wrong... its actually 2010cm (guessing metric).

So then i thought well maybe its the outside of the tire. 90/90/21 is 2128cm (well getting closer.... but still not 100%).

So i could set it to either the circumference of the tire or the wheel... But which is it?

Tire will be 120/75/16.5

101900


TIA
