Stator for Honda CR, Yamaha YZ & Suzuki RM
CR 125, 250 and 500, YZ 250 and RM 125, 250 - part number RM01294
This is a brand new aftermarket stator for Honda CR 125, CR 250 and CR 500 models from 1984 to 1986, Yamaha YZ 250 from 1985 to 1986, and Suzuki RM 125 from 1989 to 1993 and RM 250 from 1986 to 1993. It replaces a long list of Honda and Yamaha part numbers, including 31120-KA3-741 and 56A-85510-K0-00, so a single unit covers several closely related machines.
This is a compact two-wire stator, 58 mm across the outside and 16 mm thick, with only 75 mm of lead from the winding out to the terminals. The original grommet is reused and the supplied connector is fitted, after which it goes back in as a plug-and-play part. The core uses the highest grade lamination materials and the winding the highest grade copper, resistant to 200 degrees Celsius, which matters on air-cooled two-strokes where the ignition side runs hot.

Frequently Asked Questions
Does this stator need any modification to fit?
No modification to the bike is required. The only assembly step is reusing your original grommet and fitting the new connector, after which it goes back in exactly as the original did.
What is included in the box?
A new stator complete with connector and wires. The original grommet must be reused, so keep it when the old unit comes out.
How do I tell whether my old stator has failed?
Measure between the white and red wires with a multimeter. The reading should be 160 ohms plus or minus 20 percent. An open circuit, a very low reading, or continuity between either wire and the stator body means the winding has failed. A weak or missing spark and a bike that becomes hard to start once hot are the usual symptoms.
One part number covers three makes. How do I confirm it is right for my bike?
Compare the number on your original unit with the cross reference table, and check the physical size: 28 mm interior diameter, 58 mm exterior diameter, 16 mm thick, two wires with a short 75 mm lead. These models share the same ignition stator design, which is why one part covers Honda CR, Yamaha YZ and Suzuki RM applications.
