ABS - Watch Your Modifications
On page 56 of the08 touring modelsowners manual is a interesting piece of information.
It says "ABS motorcycles must always use tires and wheels that are the same as the original equipment."
It goes on to say if you change to different size tires or wheel diameters you can upset the ABS calibration and it will not work the way it was designed.
Read the whole thing yourself and check it out with your dealer before you make any changes that might upset the ABS system.

This is the case with cars and trucks equipped with ABS as well. Slip threshold is calibrated to have a small buffer to account for noise. Different size tires can cause a speed difference greater than the buffer and cause false triggering. Not a good thing!

Yes it says that in the book. It also says Never use after market parts on your Harley. Page 5 says don't operate with the forks locked. I didn't expect HD to say yes it ok to change wheel size. The sensor is in the bearings, after lots of checking I'm going to keep mine 21/18's
