Had mine break out a couple of times on gravel patches on Lincolnshire's finest Russ. What tyre's are on the new CT ? Have you been chasing that GS too hard ?
Just found this.
When the rear wheel is unable to maintain traction through its contact patch, it slides, and the rotation of the rear wheel no longer matches the rotation of the front wheel. The sensors relate this information to the bike’s ECU. Since the ECU controls fueling and engine speed, it already knows the amount of power the bike is delivering to the rear wheel. In some cases, it also registers throttle position, gear position and even lean angle. With the combination of wheel speed sensor data and engine speed data, the ECU can make a determination on available traction, and trigger one or more responses
Have you maybe got a rather sensitive sensor ?
