MOTOR METER RACING 85mm 3-3/8″ W PRO 2 in 1 GPS Speedometer Tachometer
Best for: Builders who want GPS-based accuracy in a rugged 2-in-1 unit. Why: Combines speed and RPM data with a white dial and red LED for clear daytime visibility. Caution: Installation may require panel space to accommodate the 85mm diameter and behind-panel clearance.
Digital Chainsaw Tachometer Adjustable Backlight
Best for: Riders needing a backlit, adjustable RPM gauge for small engines or ATVs. Why: Backlit readability and calibration options suit variable lighting. Caution: Ensure mounting space fits behind-panel clearance for the gauge.
0011 Digital Gauge Motorcycle Speedometer/Tachometer/Odometer
Features include high-quality ABS shell, speedometer, tachometer, odometer, gear oil meter, and LED indicators for headlights and signals. Best for: Universal dashboards needing several functions in one unit. Why: Consolidates speed, RPM, and indicators in a single panel. Limitation: May require calibration for exact speed reading and careful installation per provided notes.
ARTILAURA GPS Speedometer with Tachometer
Best for: Boats, cars, and off-road vehicles needing GPS-based speed data. Why: GPS signal avoids traditional speed sensors, with a 0-120 MPH range and 0-8000 RPM tachometer. Caution: Requires clear sky view for optimal GPS performance; installation notes specify panel fit and rear clearance.
Universal Motorcycle Speedometer with Tachometer
Best for: Motorcycles needing a full data dashboard in one unit. Why: 12V digital speedometer with multi-function data display and turn signal indicators. Caution: Some units may require calibration for both MPH and KM/H to reflect actual ground speed accurately.
Buying Guide
What to consider when shopping for a motorcycle tachometer speedometer combo:
- Display type and readability: GPS vs. sensor-based, backlit or anti-glare LCD, dial diameter (85mm/3-3/8 inches) to fit your gauge cluster.
- Data scope: Speed, RPM, odometer, trip meters, indicators (turn signals, high beam), and additional functions like voltage or oil level.
- Power and wiring: 12V systems, installation complexity, and compatibility with existing wiring harnesses.
- Weather performance: Waterproof/IP rating for motorcycles, boats, or all-terrain vehicles.
- Sky visibility (for GPS units): GPS speed accuracy depends on sky view; ensure mounting provides clear signal.
- Calibration needs: Some models require manual calibration for speed or RPM accuracy. Check the included instructions.
- Panel fit and space behind the dash: Ensure the unit fits into the board and has enough clearance behind for connectors.
