My ABS failed 2 years ago. I tried to have it rebuilt, but with no success. Could have saved myself months of time, effort, (and a lot of money), in teardowns/rebuilds if someone would have told me that simply removing the ABS unit, and rigid brake lines, and replacing the system with one Speigler rear brake line would have given me my bike back. I have removed the ABS unit, put the control circuit board in protective plastic, and now have a fully functional motorcycle, (without ABS). Speedo, Brakes, Cruise Control, everything works fine; I have a normal MC with normal brakes with minimal costs.
