Frequently Asked Questions

Will this CDI box fit without any modification?

Yes, this is a direct plug-in replacement for the Honda CB 250 Nighthawk and CMX 250 Rebel and requires no modification to install.

What is included in the box?

One complete CDI ignition module, ready to fit in place of the original.

How do I know my old CDI has failed?

Common signs include no spark, an engine that turns over but will not start, intermittent misfiring, or a sudden loss of power while running. The most reliable test is swapping in a known-good unit from the same year/make/model.

Is this CDI covered by warranty if it fails?

No. Due to the sealed electronic nature of CDI units, they cannot be tested for a fault before fitting and are excluded from warranty and non-refundable once fitted or tested, as noted above.
