12-Pole Stator for Honda TRX 300 Fourtrax and TRX 300 FW
Honda TRX 300 Fourtrax and TRX 300 FW - 1988 to 2000 - OEM reference 31120-HC4-014 and 31120-HC4-004
A brand new 12-pole replacement stator for the Honda TRX 300 Fourtrax and the four-wheel-drive TRX 300 FW, built as a direct replacement for the original unit fitted from 1988 through to 2000. It is a plug-and-play, direct fit part: six wires into two plugs on six pins, laid out as the original, so the stator seats in the same position inside the cover and the loom reconnects with no cutting, splicing or adapting. Part number RM01289 cross-references the Honda original part numbers 31120-HC4-014 and 31120-HC4-004.
The 12-pole winding is built on highest grade lamination materials with highest grade copper insulated to 200 degrees Celsius, which is what keeps a long-serving utility quad charging properly through repeated heat cycles. Two bench checks confirm the unit: the alternator winding reads 0.4 ohms yellow to yellow, and the pickup reads 335 ohms from blue/yellow to green, each within a 20 percent tolerance. The stator measures 88 mm across the outside, 34 mm through the centre and 15 mm thick, matching the original envelope, and the harness runs 65 mm from the stator to the grommet then a further 290 mm to the plug. The pickup pulsar coil, the connector and the rubber grommet are supplied on the assembly, and all units are tested before shipment.

Frequently Asked Questions
Will this fit my TRX 300 without modification?
Yes. It is a direct replacement for the original stator fitted to the Honda TRX 300 Fourtrax and TRX 300 FW between 1988 and 2000, with the same six wires, two plugs and six pins. No cutting or splicing is required. Check the number on your existing unit against 31120-HC4-014 or 31120-HC4-004 before ordering.
Does the 12-pole design matter?
Yes. This is the 12-pole version of the TRX 300 stator. Count the poles on the unit you are removing and check it against the OEM numbers above, because a stator with a different pole count will not match the flywheel and loom on your machine.
What is included?
The stator assembly, the pickup pulsar coil, the connector and the rubber grommet.
How do I know my old stator has failed?
A battery that will not stay charged, dim lights and a weak or missing spark are the usual symptoms. With a multimeter you should see 0.4 ohms yellow to yellow and 335 ohms blue/yellow to green, each within 20 percent. An open circuit reading, or continuity between a winding and the stator plate, means the unit has failed.
