1350 mmProduct descriptionThese Speed Sensors are responsible for the transmission of the wheels rpm rate to the speedometer unit. They are suitable for attachment to either the front wheels suspension assembly or the engine casing at the rear. The differently sized wiring adapters allow their fitting to all common vehicle types. Suitable brackets for easier mounting are necessary. The Active Speed Sensors can detect the wheels fixings to register the rotation speed, although a magnet always provides a more solid signal transponder. If you are looking for a more simple plug & play solution, our very own Speed Sensors are ideal! They can be securely mounted in position on your scooter using the existing PIAGGIO speedometer drive facility. Our Speed Sensors are not only unobtrusive, but also extremely robust and reliable in all conditions. – TIP : Do not forget to order our speedometer/rev counter for perfect results!
