The speed kit is composed of 1 phonic wheel and 1 magneto resistive speed
sensor.
The phonic wheel is made of Teflon and is composed of two separate parts: an
internal ring, which includes 4 magnets, and an external bushing, which protects
the internal ring. The external bushing is fixed to the internal one using 2 hex-key
screws. The magneto resistive speed sensor is composed of a sensing end,
included inside the brass threaded cylinder, and of a 10” (250 mm) long cable to
be plugged into the gauge’s SPEED input.
