Speed sensor

Digital speedometer like those found in a suzuki shogun 125 and raider 150 wherein there is no cable attached to front end of the bike uses the so called, GEAR TOOTH magnetic sensor, as shown in the picture.













This is bolted in the area where the front sprocket shaft is as shown below

As the gear spins or turns, each spline or tooth in it will be detected by the magnet as it passes and a corresponding electrical pulse is sent out. The faster the gear spins the faster the electrical pulses the sensor sends and thus a speed reading is made.
