Think I have ABS problem on my XTown 300i figured out. On mounting new Heidenau Tire and seating bead, hose on my compressor blew out.
Put tire and wheel in car, went out to buy new hose, but would be passing by Cycle Gear (where they know me) and knowing they have AIR------here is problem, he put wheel on tire machine disk side down because 90 degree valve stem faces other way----first charge of air, bead popped.
Took tire home, bought new compressor hose, let air out to install "Ride On", put wheel back on, took test ride. ABS light came on in usual way and went out as it all ways does at bottom of my driveway....and came back on after a few blocks.
Solution: ABS Pick UP Disk got bent in on tire machine, when wheel installed on bike, too much clearance on Pick Up. I have bent it out, crudely, bringing contact distance back to where it works....and light stays out. Long test ride today to see if light stay out and front ABS functions.
