This is a brand new aftermarket stator for the Honda CRF 250 F, built as a direct replacement for the original unit. It is a plug-and-play, direct fit part: the 12-pole core, the three plugs and the wire lengths follow the factory item, so it installs into the ignition cover and connects to the standard loom with no modification.
It uses the highest grade of lamination material and the highest grade of copper winding, resistant to 200 degrees Celsius. The pick-up pulsar coil, connectors and rubber grommet are included with the stator, and all units are tested before they are shipped.

Frequently Asked Questions
Will this fit my bike without modification?
Yes. It is a direct, plug-and-play replacement for the original Honda stator on the CRF 250 F, and the connectors and mounting points match the factory unit. No cutting or splicing is required.
What is included?
The pick-up pulsar coil, the connectors and the rubber grommet are supplied with the stator.
How do I know my old stator has failed?
Look for a battery that will not stay charged, dim or flickering lights, or no spark. A multimeter check is the confirmation: the alternator winding should read about 1.1 ohms from White to ground and the pick-up about 233 ohms White/Yellow to Blue/Yellow, each within plus or minus 20 percent. Open circuit, a short to the core, or values well outside those figures indicate the stator has failed.
Which years of CRF 250 F does this cover?
This part covers the Honda CRF 250 F from 2019 to 2025 and replaces Honda OEM part number 31120-K99-A01.
