Rally Computer 2 is a professional device for use in flat races, off- road and navigation rallies. The functionality and ability to reset the tripmeter on the handlebar makes it very popular for motorcycles and ATVs .

The housing is made of aluminum and is waterproof protecting against external factors.

High-end electronics componentd ensure reliable operation and high-precision measurement.

Measurement results are presented on a super-bright, red LED display.

The tripmeter is operated using a 3-button keypad and the 4-button reset switch. These buttons have been permanently assigned to most measurement functions.

Rally computer 2+ is used to measure distance, speed, car voltage and course [GPS]




The tripmeter should be installed in a visible place, allowing the user easy access

to the front panel. The tripmeter comes with two M5 screws. The gap between the screws is  

40 mm.

Do not install the tripmeter in places that may cause its damage or malfunction such as : air bags area, air outlets and in places that may put the car and the driver at risk.

NOTE !  Turning  off the device does not cut the power supply completely. The tripmeter still consumes some power (reduced to minimum). When the device is not in use, it is advisable to disconnect it from the car electric installation which will prevent from discharging the battery. For best result it is recommended to install an external switch that totally disconnects the power supply.


The power supply should be reliable and stable providing power between 8 and 30 V.

This diagram below shows how to connect the tripmeter.


[azi] Connection to Garmin

The tripmeter is connected with Garmin using a Garmin cable equipped with a Superseal-type  connector. The signal transmission is performed using the RS232 standard.

Wires used with Garmin devices:
