Every standard speedometer has tolerances, wich can introduce also significant spreads in speed shown. Moreover speed reading is linked to tyre diameter and gear ratio. After a gear ratio change (after crown wheel or pinion replacements) the speed displayed on the stock speedometer may be very inaccurate. For example decreasing by one pinion theeth you can introduce a 7% error. How to obtain accurate readings, then? It is not necessary to use a precision instrument, a speed calibrator is sufficient. The speed calibrator correctly adjusts the signal coming from the sensor
Speed Clibrator must be connected between the sensor and the speedometer and corrects real-time the speed signal.
Thanks to its small size and weight, it can be mounted in very confined spaces. Internal resin coating renders the system rugged and vibration proof. Installation and set up are fast and easy.
