High Output Generator Stator 200 W - Honda ATC 250 and TRX 250 R
Honda ATC 250 / TRX 250 R 1985-1989 - Part number RM01011
This is a brand new high output aftermarket stator producing 200 watts, built as a direct replacement for the original unit on the Honda ATC 250 and TRX 250 R. It delivers 20 per cent more output over stock and works with all other OEM components, so it suits any machine running added lights, a winch or other electrical load the standard charging system was never designed to carry. Installation is plug and play: it uses the original 88 mm outer diameter, 34 mm inner diameter and 17 mm thickness, with 35 mm between the fixation hole centres.
It is built with the highest grade lamination materials and wound with the highest grade copper, resistant to 200 degrees Celsius, which is what allows it to carry the extra output without overheating. It arrives complete with the pickup pulsar coil, connector, rubber grommet and back plate fitted, and every stator is tested before it ships. Our wire colour code may differ from your original: all wires are installed in the correct order, so do not change the wiring configuration.

Frequently Asked Questions
Do I need to modify anything to fit this stator?
No. It is a direct plug-in replacement, matching the original 88 mm outer diameter and 35 mm fixation hole centres, and it works with all other OEM components, so the flywheel, CDI, regulator and harness are retained. Always use a locking compound when bolting the stator in.
What is included in the box?
The stator is supplied complete with the pickup pulsar coil, connector, rubber grommet and back plate, all already fitted. The flywheel, regulator rectifier and CDI unit are not included.
How do I know my old stator has failed?
Check the AC output, then measure the windings: 0.4 ohms plus or minus 20 per cent white to ground, 115 ohms plus or minus 20 per cent pickup green to blue, and 210 ohms plus or minus 20 per cent source black/red to ground. Battery condition is extremely important, because no stator can work correctly with a weak battery, so fully charge it before any charging system test.
What should I check while the stator is out?
Replace any burned or corroded connectors on the stator and regulator rectifier, and repair any melted wiring, otherwise the same fault returns. Use high temperature dielectric grease on all connectors. Because the pickup coil is included, set its air gap as close as possible and no less than 0.010 in. Disconnect the battery before servicing.
