[5-pin AC-CDI] High-performance AC ignition module, compatible with 50–125 cc horizontal CH80/NC50 engines for ATVs, scooters, and motorcycles. Universal CDI ignition module.

【Important Product Information】

This is a 5-pin AC CDI ignition system, specifically designed for small, horizontally mounted vehicles with engine displacements from 50 to 125 cc. It is fully compatible with classic models such as the Honda CH80 and NC50, as well as ATVs, scooters, and other vehicles with similar ignition systems. As the central control unit of the ignition system, it significantly improves starting performance, low- and mid-range torque, and high-end response through precise ignition timing control. This makes it the ideal choice for replacing faulty original parts or for performance optimization. Precise Compatibility: Fits horizontally mounted engines with AC ignition systems in 50 cc, 70 cc, 90 cc, 110 cc, and 125 cc displacements. Connection: Standard 5-pin connector (please ensure the original CDI is a 5-pin AC type). Compatible vehicle models: Honda: CH80 (Elite), NC50 (Tact). Common vehicle models: Most ATVs, scooters, small ATVs, and motocross bikes with horizontal engines. Important checks: Before installation, you must check the number of pins (5 pins), their color sequence, the type of ignition system (magneto ignition with coil), and the engine's mounting position (cylinder parallel to the ground). Incompatibility will prevent the vehicle from starting.
