This is a brand new aftermarket lighting stator, built as a direct replacement for the original unit fitted to the Honda CRF 450 X. It is plug-and-play and a direct fit, so it mounts on the original fixings behind the ignition cover and connects to the standard loom with no modification to the engine cases or the wiring. Every unit is tested before it is shipped.
This is the lighting specification stator, carrying six wires across two plugs: the alternator lighting coils, the ignition source coil and the pick up pulsar coil, which is supplied already fitted to the assembly. It is built on the highest grade of lamination materials and wound with the highest grade of copper winding, resistant to 200 degrees Celsius, which matters on an enduro engine that spends long stretches at low speed with little airflow over the cases. Connectors and a rubber grommet are included with the part, along with the opposite connector for the main harness side, as that plug is often melted, corroded or defective and is a major cause of repetitive electrical issues.

Frequently Asked Questions
Does it fit without modification?
Yes. It is a direct replacement for the original unit on the CRF 450 X years listed above, using the original mounting points and the two standard plugs. No cutting, splicing or modification of the cases or harness is required.
What is included?
The lighting stator, the pick up pulsar coil, the connectors and a rubber grommet, plus the opposite connector for the main harness side so a melted or corroded plug on the bike can be renewed at the same time.
How do I tell that my old stator has failed?
Common symptoms are lights that are dim, flickering or dead, a battery that will not stay charged on models fitted with one, a weak spark, or an engine that cuts out when hot. The figures above allow a quick check: about 0.4 ohms yellow to white, 2.0 ohms from either of those wires to ground, about 241 ohms across the pickup, and about 20 ohms across the source coil. Readings well outside those values point to a shorted or open winding.
Why does this one have six wires when some CRF stators have fewer?
This is the lighting specification stator for the CRF 450 X. The six wires cover the alternator lighting coils, the ignition source coil and the pick up pulsar coil, which is why it uses two plugs. Check the OEM number 31120-MEY-672 against your original unit if you are unsure which version your machine carries.
