Koso KOS-BB551B20 2-3/8" Digital Tachometer Silver

The digital HD-01R Tachometer for Harley-Davidson® gives precious informations on the oil pressure, and its warning function could also save the engine from bad damage. This instrument will fit with the OEM oil pressure sensor. To make the needle stable for the high vibrations, we adopt the stepper motor on all our needle meters. With the auto-scan function, the HD-01R Tachometer for Harley-Davidson® will scan when the engine is turned on. This tachometer with illuminated needle is very easy to read at night. Want something different? This is the right meter.

* IMPORTANT:  Will not work with CANBUS system
