Yamaha OE / Replacement Numbers
- 5VY-81410-00-00 – original early YZF-R1 stator reference
- 2D1-81410-00-00
- 2D1-81410-01-00
- 2D1-81410-10-00 – later Yamaha superseding stator reference
These Yamaha numbers are supplied for identification and cross-reference only. This listing is for an aftermarket replacement stator and is not represented as Genuine Yamaha.
Reference Dimensions
Specialist replacements for this Yamaha OE family are commonly specified at approximately:
- Stator inner diameter: 18 mm
- Stator outer diameter: 68 mm
- Stator thickness / stack depth: 42 mm
- Wire length from stator to grommet: approximately 125 mm
- Wire length from grommet to plug: approximately 500 mm
Some aftermarket manufacturers measure the winding stack slightly differently, so use the product photographs, connector and original OE number as the final fitment check.
Electrical Reference
A specialist replacement for this OE family specifies approximately 0.4 ohm ±20% resistance between each pair of alternator output wires. Resistance should be even across all three phases and there should be no continuity from an output wire to the stator core / earth.
Important Fitment Checks
- Compare the original Yamaha OE number where available.
- Confirm the stator body diameter, centre bore and mounting-hole arrangement match the original.
- Compare the rubber grommet position and wiring length.
- Confirm the motorcycle has the matching 3-pin charging-system connector.
- Check the regulator/rectifier, connector condition and charging-system wiring before replacing the stator.
Installation Advice
Disconnect the battery before electrical work. Inspect the generator rotor, stator cover and wiring for heat damage, loose magnets, burnt connectors or contamination. Use thread-locking compound on the stator retaining screws where specified by the workshop manual, route the cable through the original grommet correctly and prevent the wiring from contacting the rotor.
After fitting, verify charging voltage and AC output before returning the motorcycle to service. A failed regulator/rectifier or damaged connector can cause repeat stator failure.
Package Contents
