How to identify the right two-wheeler spare part by part number

Ordering by vehicle model gets parts wrong. Ordering by part code gets them right. A practical guide to finding, reading and verifying two-wheeler part numbers.

Every parts counter in Mumbai has the same conversation twenty times a day. A customer names a bike, a year and a variant; the counterman pulls a part; it does not fit. Nobody was careless. The model simply is not enough information.

Manufacturers revise components mid-production without renaming the vehicle. A switch assembly, a CDI unit, a cable length or a piston grade can change inside a model year. This is why every serious distributor indexes stock by manufacturer part code, and why we made our catalogue of 8,039 parts searchable by code as well as by description.

Where to find the part number. On electrical items it is usually moulded into the housing or printed on a label on the flat face - look at the back of a CDI unit, the base of a regulator-rectifier, or the connector shroud on a switch. On mechanical parts it is stamped or cast into the body: piston crowns carry a grade mark, brake shoes carry a code on the web, cables have it on the ferrule or a sleeve near the adjuster. Where the part itself is unmarked, the old packaging or the vehicle service manual will carry it.

Read the whole code, including the suffix. The suffix is where the money is. A code ending in a grade letter on a piston assembly tells you the oversize; a series number on a switch assembly (the 685 series is the classic example) tells you which harness it mates with. Dropping the last two characters because they look like packaging noise is the single most common ordering error we see.

Verify before you order, not after. Search the code in our catalogue. If the description that comes back names a different system or a different vehicle class than you expect, stop - you have either misread a character or you are holding a superseded part. Ones and sevens, and letter O against zero, cause most of it.

When the part is unmarked or destroyed. Photograph it against a ruler, capture the connector shape and pin count, and send that with the vehicle details. On cables, measure the outer sheath end to end and the inner wire beyond it, and say which end fitting is which. That combination identifies a cable far more reliably than a model name.

Keep a record. Workshops that log the part code against the job the first time never repeat this exercise. Six months later, when the same customer returns with the same complaint, the order takes ten seconds.

If you have a code and need to know whether it is in stock in Mumbai, send it to us. A same-working-day answer on availability is the least a distributor should offer.

Questions we get asked

Frequently asked questions

What if I cannot find the part number on the old part?

Photograph the part against a ruler, capture any connector shape and pin count, and send it with the vehicle model and year. Between the image and the application we can usually identify it.

Are part numbers the same across brands?

No. Each manufacturer runs its own numbering. A Varroc code and a Uno Minda code for the same function will look nothing alike, which is why our catalogue lists the brand against every code.

Need the part discussed here?

We stock it. Send the part code for same-working-day confirmation.
