Guide for choosing your motorcycle electronic components
Choosing an electronic module depends mainly on its compatibility with your ignition system and the power of your engine.
Compatibility is the primary criterion. Check the number of connector pins (for example, 4, 6, or 8 pins) and the type of current (AC or DC) required by your motorcycle or scooter. An unsuitable module will not allow the engine to start.
Engine power influences the choice of case. Some modules are designed for specific displacements, such as engines from 50 to 125 cm³. Others, like CDI for GY6, integrate speed adjustments via DIP switches to optimize performance.
Heat resistance is an important technical feature for longevity. Ensure that the module case is designed to withstand the high temperatures generated by the engine during use.
Technical criteria for selecting your electronic module
| Criterion | Selection advice |
|---|---|
| Connector compatibility | Check the number of pins (4, 6, or 8) and the connector configuration to ensure a correct physical connection with your vehicle. |
| Current type | Identify whether your system requires an AC or DC module. Using an incompatible type can prevent the ignition from functioning. |
| Engine displacement | Select a module suitable for your engine's power, for example for displacements between 50 and 125 cm³. |
| Thermal resistance | Prefer a case capable of withstanding high temperatures, such as 105 ℃, to ensure component reliability. |
Frequently asked questions about motorcycle electronics
How to choose the right CDI module for my motorcycle?
The choice depends on the number of connector pins, the type of current (AC or DC), and the engine displacement. Check these specifications before purchasing.
What is a DIP switch on a CDI case?
A DIP switch allows you to adjust the settings of the card, such as the speed range, to optimize engine performance according to your needs.
What maximum temperature can a CDI module withstand?
Some modules are designed to withstand temperatures up to 105 ℃, which is essential for their long-term reliability.
