Product Number: 18607N
The WAI 18607N is a brand-new 12V Mitsuba PMDD starter motor. It is replacing Honda original-equipment numbers 31200-HN5-671, 31200-HN5-A81 and 31200-HN5-M01, as well as the Remy reference RS41225. Sourced directly from WAI and supplied new, it is a like-for-like replacement for worn or failed units carrying these Honda or Remy references.
Built to the Mitsuba PMDD (Permanent Magnet Direct Drive) design, the 18607N operates on a 12V circuit with counter-clockwise (CCW) rotation — confirming the correct drive direction before fitting is essential. Permanent magnet direct drive technology removes the need for field windings, keeping the motor compact and delivering reliable cranking performance from a straightforward electrical circuit.
The 18607N carries 7 OE cross-references in total across Honda and Remy, covering the three hyphenated Honda numbers and their condensed equivalents alongside the single Remy reference. Use our cross-referenced catalogue or the selection widget to verify the correct fit against your OEM number before ordering — every reference shown is backed by our Fit Guarantee.

A. The 18607N replaces six Honda OE references: 31200-HN5-671, 31200-HN5-A81, 31200-HN5-M01, 31200HN5671, 31200HN5A81 and 31200HN5M01 — these are the hyphenated and condensed variants of the same three part numbers. Search our cross-referenced catalogue by any of these numbers to confirm the match, or use the selection widget if you have your machine model to hand. Every OE reference shown is backed by our Fit Guarantee.
A. Yes. Remy RS41225 is one of the 7 OE cross-references listed for the WAI 18607N, alongside the six Honda numbers. If your current unit carries the Remy reference, the 18607N is the corresponding replacement. Search our catalogue by that reference number to verify, or ask Simon if you need further confirmation.
A. The 18607N rotates counter-clockwise (CCW) when viewed from the drive end. Fitting a motor with the wrong rotation direction will cause it to spin the ring gear backwards and fail to start the engine. Always confirm your application requires CCW rotation before ordering.
A. PMDD stands for Permanent Magnet Direct Drive. It means the motor uses permanent magnets in place of wound field coils, and the drive pinion engages the ring gear directly without a gear reduction stage. The design is compact, electrically straightforward, and well suited to the applications for which this Mitsuba unit was originally specified.
A. It is supplied brand new — not remanufactured or reconditioned. The condition is confirmed as Brand New in the product specification.
A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
