3. Setup and Installation
Installation should ideally be performed by a qualified technician. Ensure the motorcycle's power is off before beginning installation.
3.1 Wiring Instructions
The speedometer connects to your motorcycle's electrical system via multiple connectors. A detailed wiring diagram is typically included in the product package. Please refer to that diagram for specific wire color codes and their corresponding functions (e.g., power, ground, ignition, turn signals, high beam, fuel sensor, speed sensor, etc.).
General Wiring Tips:
- Connect the main power (usually red wire) to a switched 12V source.
- Connect the ground wire (usually black wire) to the motorcycle chassis.
- Connect signal wires (e.g., turn signals, high beam) to their respective circuits.
- Ensure all connections are secure and insulated to prevent short circuits.
3.2 Speed Sensor Installation (for models with sensor)
If your package includes a speed sensor, install it according to the following general guidelines:
- Mount the speed sensor securely near a rotating part of the wheel (e.g., brake disc bolts, wheel spokes) using the provided hardware.
- Ensure the sensor is positioned to detect the magnets (if included) or metal protrusions on the rotating part.
- Adjust the gap between the sensor and the rotating part to the recommended distance (usually a few millimeters) for accurate readings.
- Route the sensor cable safely, away from moving parts and heat sources, and connect it to the designated input on the speedometer wiring harness.
4. Operating Instructions
4.1 Power On and Initial Display
Upon turning on the motorcycle's ignition, the speedometer will perform a self-check, illuminating all indicators briefly before settling into its normal display mode.
4.2 Adjusting Backlight Color
The instrument features a 7-color adjustable backlight. To change the backlight color:
- Under the ODO (Odometer) display condition, press and hold the right button on the instrument.
- The backlight color will cycle through the available 7 colors. Release the button when your desired color is displayed.

4.3 Switching Mileage Units (km/h and mph)
To switch between kilometers per hour (km/h) and miles per hour (mph):
- In the ODO mode of the working interface, long press the button to toggle the speed unit.
- The display will show either 'km/h' or 'mph' accordingly.

6. Maintenance
To ensure the longevity and optimal performance of your RYSJM Motorcycle Dashboard Speedometer, follow these maintenance guidelines:
- Cleaning: Use a soft, damp cloth to clean the display and casing. Avoid abrasive cleaners or solvents that could damage the plastic or LCD screen.
- Wiring Inspection: Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure insulation is intact.
- Sensor Check (if applicable): If your model includes a speed sensor, inspect it for dirt or damage. Ensure the magnets (if used) are clean and properly aligned with the sensor.
- Environmental Protection: While the unit is designed to be waterproof and impact-resistant, avoid prolonged exposure to extreme weather conditions or direct high-pressure water sprays.
7. Troubleshooting
If you encounter issues with your speedometer, refer to the following common problems and solutions:
- No Power/Display:
- Check the main power and ground connections.
- Verify the motorcycle's battery voltage is sufficient (12V).
- Inspect the fuse in the motorcycle's electrical system.
- Inaccurate Speed/Odometer Readings:
- Ensure the speed sensor (if installed) is correctly positioned and the gap to the rotating part is appropriate.
- Check the speed sensor wiring for damage or loose connections.
- Verify the wheel circumference setting (if adjustable on your model, refer to the full product manual for adjustment steps).
- Indicators Not Working (e.g., Turn Signals, High Beam):
- Check the specific wiring for the affected indicator.
- Ensure the motorcycle's original indicator lights are functioning correctly.
- Backlight Not Changing Colors:
- Ensure you are in ODO mode before attempting to change colors.
- Press and hold the right button firmly.
For persistent issues, consult a professional motorcycle technician.
8. User Tips
- Compatibility Check: While this speedometer is designed for universal 12V motorcycles, specific models may require custom mounting brackets or wiring adaptations. Always verify compatibility with your motorcycle's electrical system and physical space before purchasing and installing. For example, for older models like a Moto Guzzi Breva 1100 (2006), professional installation or specific adapter harnesses might be necessary.
- Professional Installation: Due to the complexity of motorcycle electrical systems, professional installation is highly recommended to avoid damage to the unit or the motorcycle.
- Secure Mounting: Ensure the speedometer is mounted securely to prevent vibrations from affecting its performance or causing damage during riding.
