This Race Tachometer works independently from the Bike’s Electrical System. It has its own Battery and signal pickup from the Sparkplug wires. it is very robust and reliable. This Model counts one Cylinder Spark as on Rotation.
I have 2 for sale. Both function without any problems, the Battery is in good condition.
Special Charging Cable is included. One Tach has very thin crack in the glass (€150) the other one is flawless (€175)
