Makes total sense. In any RBW system, the bike’s main computer looks at several sensors to determine when and how far to open the throttle plates, which are not physically controlled by the rider. The ECU compares what you’re requesting at the throttle grip to a pair of sensors on the throttle rack itself, one that’s part of the drive motor that, in effect, says, “Here’s where the throttle plates should be.” And there’s another, separate sensor that confirms, “Yes, that’s how far they’re open.” If any of those key sensors disagree, the ECU goes into a safe mode. You certainly don’t want a bike as powerful as the XR to default to maximum power, do you? The broken wire took one of those sensors out of the loop.
