Stator for Honda TRX 250 Fourtrax Recon and TRX 250 EX Sportrax
Fits TRX 250 Recon TM and TE 1997-2004 and TRX 250 EX Sportrax 2001-2005 - Part RM01309
This is a brand new aftermarket stator for the Honda TRX 250 family, covering the Fourtrax Recon TM and TE built between 1997 and 2004 and the TRX 250 EX Sportrax built between 2001 and 2005. The stator sits inside the left-hand engine case behind the flywheel and does two separate jobs at once. Its alternator windings generate the alternating current that the regulator rectifier turns into charging voltage for the battery and the lights, while the pick-up and source coils feed the ignition system with the timing signal and the energy it needs to fire the plug.
Because both functions live on the same plate, a failing stator on these machines can present in two quite different ways. Sometimes it is purely a charging fault - a battery that goes flat overnight, dim lights at idle, a machine that will start on a jump but not on its own. Sometimes it is an ignition fault instead - an intermittent misfire that gets worse as the engine warms up, a sudden cut-out, or a machine that will not spark at all. This replacement is a direct fit for the original Honda unit, wound with the highest grade copper and insulated to 200 degrees Celsius, built on high grade laminated cores, and supplied with the pick-up pulsar coil, the connector and the rubber grommet already fitted. Every unit is tested before it is shipped.

Frequently Asked Questions
Will this fit without modification?
Yes. It is a plug-and-play direct fit for the Recon TM and TE from 1997 to 2004 and the TRX 250 EX Sportrax from 2001 to 2005. The plate, the harness route and the connectors match the original, so no cutting or splicing is required. Check the OEM number on your existing unit against 31120-HM8-004 before ordering.
What is included in the box?
The stator assembly, the pick-up pulsar coil, the connector and the rubber grommet. Everything is pre-fitted, so the unit goes in as one piece.
How do I know my old stator has failed?
Measure with a multimeter on the ohms range. Between each yellow wire you should read about 0.4 ohms. Blue/yellow to green should read about 280 ohms, and black/red to green about 190 ohms, all plus or minus 20 per cent. Any reading that is open circuit, or any continuity between a winding wire and the metal body of the stator, means the unit has failed.
My machine has no spark rather than a flat battery - can the stator still be the cause?
Yes. On this model the same plate carries the pick-up and source windings that feed the ignition, so a break in either one will cause a misfire or a complete loss of spark while the charging side may still appear to work. That is why the specification lists three separate resistance readings - all three need to be within tolerance for the unit to be healthy.
