Another simple thing to check: check tire pressures front and back and adjust if necessary.
Couple of times I had been remiss in checking pressures and figured it out when ABS light came on. (Changes in tire pressures change the tire circumference and hence the relative rotation rates which makes the ABS computer think something ain't kosher with the ABS system.)
I knew someone else that had that problem or a similar one and it had to do with him backing up at a speed greater then 6mph. Does it do it when you back up slower?No it has stayed on
Rocky: I certainly understand the skepticism but it has happened at least twice and the ONLY thing done that resolved the ABS warning light was adjusting air pressure. Not sure what else it could be.Jim.with all due respect.No way..
Darksiders guys run tires that aren't OEM OD all the time and no such thing has happened.
I think it was just a coincidence what you found,but not the cause of why the light came on.
In the past I have had a dusty sensor on my own and two other bikes that triggered the ABS light.
