Product Number: 18340N
The WAI 18340N is a brand-new 12V, 0.2kW permanent-magnet direct-drive (PMDD) starter motor. It is manufactured by Denso, supplied as a direct replacement for original-equipment Denso and Yamaha units. Designed to restore reliable engine cranking, it crosses to 17 OE references including Denso 128000-1990, 128000-4850, 128000-4851, 128000-4852 and 128000-4854, Remy RS41269, and Yamaha 55X-81800-50-00, 55X-81800-51-00, 65X-81880-50-00 and others — search our cross-referenced catalogue by any of these numbers to confirm fit.
The PMDD design uses permanent magnets in place of wound field coils, resulting in a compact, lightweight unit that delivers consistent cranking torque with minimal electrical draw. Clockwise rotation matches the OE specification, ensuring correct engagement with the ring gear without modification.
Being brand new — not remanufactured — the 18340N carries full new-component integrity. It is sourced and supplied under the WAI brand, a recognised name in rotating electrics.

A. The WAI 18340N crosses to 17 OE references in total. The Denso numbers it replaces include 128000-1990, 128000-4850, 128000-4851, 128000-4852 and 128000-4854 (plus formatted variants 1280001990, 1280004850, 1280004851, 1280004852 and 1280004854). It also replaces Remy RS41269 and Yamaha numbers 55X-81800-50-00, 55X-81800-51-00, 55X818005000, 55X818005100, 65X-81880-50-00 and 65X818805000. Search our cross-referenced catalogue by any of these numbers to confirm your application.
A. Yes — Remy RS41269 is one of the 17 OE references this unit crosses to. The WAI 18340N is supplied brand new and is a direct equivalent, matching the 12V, 0.2kW PMDD specification and clockwise rotation of the original Remy unit.
A. PMDD stands for Permanent-Magnet Direct-Drive. Instead of wound field coils, the motor uses permanent magnets to generate the magnetic field. This makes the unit more compact and lighter than a conventional starter, while delivering consistent cranking torque and placing less load on the battery and electrical system. The WAI 18340N is a PMDD unit operating at 12V and 0.2kW.
A. Yes, the WAI 18340N rotates clockwise (CW) when viewed from the drive end. Rotation direction determines how the pinion engages the ring gear, so fitting a starter with the wrong rotation can cause damage. This unit matches the OE clockwise specification of the Denso and Yamaha originals it replaces.
A. The WAI 18340N is supplied brand new — it is not a remanufactured or reconditioned exchange unit. You receive a fully new starter motor with no core charge or return of an old part required.
