Genuine Yamaha motorcycle parts are our narrowest range on purpose: the SR400 and the SR500, and very little else. This page is about where those numbers are looked up, and why the catalogues that dominate this search do not hold your machine.
What we mean by genuine Yamaha motorcycle parts
A genuine item is one Yamaha numbered, ordered through the official supply chain against a parts fiche, and supplied in that chain’s packaging. That is a description of a route rather than a claim about quality, and it is the only definition that survives contact with a bike this old.
It matters because the SR is a machine people keep rather than replace, so the question is almost always whether a number is still supplied. Our other categories are indexed on the parts hub; this is the Yamaha entry in it.
What we do not do is pretend to a full marque catalogue. We source genuine Yamaha items against a number or a frame number, and the depth is in one family.
Our Yamaha range is the SR400 and the SR500
Two machines, deliberately. The Yamaha SR400 and Yamaha SR500 pages carry the listings themselves, from fenders and exhausts to machined covers, swingarms, rims and the wear items, and there is no reason to restate any of that here.
This page is the other half of the job: the ordering mechanics behind a genuine Yamaha-numbered component, which neither model page covers. If you want to see what is on the shelf, go there; if you want to know where a number is looked up and what happens when it has been replaced, stay here.
A good deal of what an SR owner buys is not genuine at all but custom or aftermarket work with no Yamaha number attached. Both kinds go on the same quotation, and the SR quote form takes them together.
Why the big catalogues do not have your SR
The catalogues that rank for this phrase are built around Western model trees, and the SR barely appears in them. Motorcycle Classics records that the last SR500 imported to the United States was in 1981, though production continued until 1999 for Europe.
So an American catalogue holds a few years of SR500 at one end and the export SR400 at the other, with a long gap in between. Every Japanese-market SR400 built across that gap falls outside it, and those are most of the bikes still on the road.
Thailand is no help either. Thai Yamaha’s current line-up runs NMAX, XMAX, Aerox, Fazzio, Grand Filano, Finn, PG-1, R15, Exciter, XSR155 and MT-15, with no SR400 in it. The SR400 is not a current model in Japan or in Thailand.
Where a Yamaha number comes from, by market and year
The table maps the machine to the fiche that lists it. It is arranged this way because an SR owner’s failed search is nearly always a market problem rather than an availability one.
| Machine and market | Whose fiche lists it | What that means for you | Ships from |
|---|---|---|---|
| SR500, North America, to 1981 | American catalogues | Catalogued, though much of it superseded by now | Japan |
| SR500, Europe, to 1999 | European genuine-parts fiches | A longer model tree than the American one | Japan |
| SR500, Asia and Oceania | Japanese-market fiche | The widest SR500 coverage there is | Japan |
| SR400, Japanese market | Japanese-market fiche only | The bulk of what SR owners need, and the row the ranking catalogues lack | Japan |
| SR400, export models from 2014 | American and European catalogues | A later specification than the carburettor machines, with its own numbers | Japan |
| SR400 and SR500 custom and styling work | Nobody’s, because no genuine number exists | Our own listing on the two model pages | Thailand |
The last row is the hand-off. Anything with a Yamaha number behind it is a Japan question; anything made rather than catalogued is a Thailand question, and one order can hold both.
Superseded and discontinued numbers
Every maker replaces a number when a component is revised, and the old one then points at the new. That is supersession, it is normal, and it means the item you are quoted may carry a different number from the one printed in your manual.
Discontinuation is the other outcome. When a number is no longer supplied there are three honest answers: old stock somewhere in the network, a replacement number that is still made, or nothing at all. We tell you which of the three came back.
The general mechanics of back orders and obsolete numbers are on discontinued motorcycle parts. The SR consequence is that a machine out of production is one where the answer moves over time, so a quotation is a snapshot rather than a standing offer.
Frequently asked questions
Do you supply parts for other Yamahas?
We can quote genuine Yamaha items against a frame number for machines outside the SR family, but our listings and our experience are concentrated on the SR400 and SR500. Ask, and we will say plainly whether it is something we can source well.
Is the SR400 still made?
No. It is not in Yamaha’s current Thai range, so sourcing for it now runs through the genuine supply chain in Japan and through specialist making rather than through a showroom.
My manual gives a number that no longer works. What now?
Send it anyway. An old number is still the best starting point available, because it can be checked against the fiche for a replacement before anybody starts guessing from a written description.
Ordering genuine Yamaha parts through us
Send the number if you have one and the frame number if you do not, with the quantity and the destination country. A photograph of the old component is worth attaching in either case, and identifying parts from photographs explains what to shoot.
Genuine items drawn from Japan are normally available in about four working days when they are not on back order, and how that supply works is described on our parts from Japan hub and on ordering parts from Japan. Postal EMS takes four to seven days and air parcel about two weeks.
We answer in Thai Baht on a CIF basis, the goods FOB with the carriage added. Payment is by bank transfer, secure card link or PayPal, and after despatch nothing can be returned except for a manufacturer’s fault, with no returns to Thailand at all. The full terms are on our order policy.
Use the Yamaha quote request or the general form. Where you need to confirm the machine first, the frame-number guide and the number guide both help, and the model index shows everything else we cover.
