Currently only three EDR events can be stored in the motorcycle's Engine Control Unit (ECU). Once three events are recorded, no other events can be recorded. The EDR events are triggered when the motorcycle falls and goes into Emergency Shutdown (ES). In addition to the shutdown, the rear wheel would've had to been in motion within the ~10 seconds prior to shutdown. Some motorcycles take it a step further and require a deceleration of the rear wheel to trigger an event (i.e. from a hard brake). Once the bike shuts down, eight seconds of data is stored prior to the shutdown. Some of the main data parameters in a typical download include: engine RPM, throttle position, rear wheel speed, front wheel speed (if equipped), clutch position, gear position, grip position (if equipped), and more.
Various motorcycles have been instrumented to validate the pre-ES data. Road tests have been performed to validate the wheel speeds as compared to GPS based data acquisition systems. A partial list of the validated motorcycles to date can be seen below:
13-17 Ninja 300
18-23 Ninja 400
24-up Nina 500
17-24 Ninja 650
13-24 Ninja ZX-6R
16-24 Ninja ZX-10R
16-23 Ninja ZX-14R
14-24 Ninja 1000
15-16 Vulcan S
18-20 Z900RS
17-22 Z900
24-up Z500
20-22 KLX230
20-21 Teryx KRX1000
EDR capability for any particular motorcycle can be confirmed by reviewing the Owner's Manual. However, if you have an off-road vehicle, the manual may not indicate as such. As an example, the Owner's Manual for the 2020-21 KRX1000 does not make mention of its EDR capability.
