This is a brand new aftermarket generator stator, a direct replacement for the original unit on the Honda CRF 250 L and the CRF 250 RL Rally. It is a plug-and-play, direct fit part with the same 18-pole core, the same three plugs and the same wire lengths as the factory item, so it bolts back into the left-hand engine cover and plugs into the standard loom.
It is built with the highest grade of lamination material and the highest grade of copper winding, resistant to 200 degrees Celsius. The pick-up pulsar coil is included and already fitted, along with the connectors and the rubber grommet. Every unit is tested before it is 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 RL Rally 2017-2020 and the CRF 250 L 2013-2020. The three plugs and the mounting pattern match the factory unit, so no loom modification is needed.
What is included?
The stator, the pick-up pulsar coil, the connectors and the rubber grommet.
How do I know my old stator has failed?
Common symptoms are a flat battery that keeps returning, lights that dim or flicker, or a total loss of spark. Check the windings with a multimeter: the alternator should read about 0.7 ohms Yellow to Yellow and the pick-up about 231 ohms Blue/Yellow to White/Yellow, each within plus or minus 20 percent. Open circuit, a short to the core, or values well outside those ranges confirm a failed stator.
Which models does OEM number 31120-KZZ-901 cover?
That Honda part number is the original stator for the CRF 250 L from 2013 to 2020 and the CRF 250 RL Rally from 2017 to 2020, and this unit replaces it directly.
