Dynatek ARC-2 Asynchronous Restriking CDI - Dynatek

Dynatek has introduced the ARC-2 for 4 cylinder Motorcycle applications. This CDI ignition is capable of producing over 50,000 Volts at the spark plug, and has the highest spark energy of any CDI on the market. It is designed to optimize the ignition of modified vehicles, providing the strong spark needed to develop peak power for turbocharged, nitrous oxide and high compression applications. Intelligent Spark Profiling allows for less delay between successive sparks. It also features a built in launch limiter (3,000 to 11,900 RPM) for drag style launches as well as a built in retard mode (10 degrees fixed).

The lightweight and compact ignition will be offered in plug in kits for select motorcycle models that will make installation a breeze, with no need to cut into the stock harness.
