SERIOUS technology being employed on the Ducati GP 19 front wheel. With several sensors utilized for data acquisition(disc temperature, gyroscopic, wheel speed).

?*Note:The use of titanium screws*?

At the top you can just see the bottom of the suspension position sensor. Behind that, the red orange housing of the infrared temperature sensors which measures the temperature of carbon disc brakes. At the front, and hidden by a cover, is a Two axis accelerometer. One axis is measuring the acceleration in the direction of the fork legs. This sensor and the one attached to the bottom of the triple clamp is used to measure how much impact energy is absorbed by the suspension. The second axis is lateral, and measures the sideways slippage of the tire, more commonly referred to as understeer.
At the bottom, you can see two wheel speed sensors. Two sensors are fitted to each wheel, and their signals constantly cross checked against each other, to ensure values are correct. Some of the most important elements of electronics strategies depend on this information, so it cannot afford to be incorrect.

Maybe those engineers should go work for Boeing since they understand that dynamic decisions should not rely on a single sensor.

Pedrosa's crash some years ago, following a wheel-speed-sensor failure (after contact with another bike), probably prompted the redundancy on that sensor.

This reminds me ... I need to put a zip-tie around one of the fork legs on my new race bike, because that's all the data-logging I've got LOL
