I'm not sure of any other "fixes" for the issue. I bought the KTM dongle that plugs in. I have set my ABS the way I want it (front wheel - ABS enabled, rear wheel - ABS disabled) and everything works. It's that way each time I start the bike and take off. The speedo and odometer all work fine. I know it's $120 dollars. But in my mind this is one of those electronic things that ya just bite the bullet and do it. Then you never look back and there are no mysterious issues on the road.
Once I wrapped my mind around the ABS off-road I like it. Ride into the corner HARD - grab a handful of brake and shut it down. No drama - just ride. What a change from the old DT Enduro days.
