The Moturo CDI ignition box for your Honda CB 250 N (MY 78-81) and Honda CMX 250 C Rebel (MY 96-99) — a typical candidate for replacement after four decades. OE connector pinout, ready for installation.

The ignition box controls the ignition timing and is the electronic heart of the system. It operates on the principle of capacitive discharge and delivers the ignition spark to the spark plug via the ignition coil. The connector and geometry follow the original part design, making it a one-to-one replacement for the factory component.

Tightening torques for the mounting screws follow the workshop manual for the respective model. Replacement takes about half an hour with a socket wrench set and a screwdriver.
