The engine code is the identifier
A code on the engine case tells you the platform and therefore what interchanges. We work from a photograph of it rather than from the model name on the tank.

Motorcycle parts
Last updated
Chinese motorcycle engines are identified by a code stamped on the case, and that code tells you more about what fits than the bike's model name does — particularly for the many machines built on licensed Japanese designs.
Once the engine is identified, most of the remaining risk is in the parts that are specified by numbers nobody quotes: chain pitch, sprocket count, carburettor bore.

What we check before you pay
Chain pitch, links and sprocket teeth
A chain is a pitch and a link count; a sprocket is a pitch, a tooth count and a bolt pattern. All of them are specifiable and none of them are usually in the listing.
Carburettor bore and jetting
Bore size, mounting spigot and jet sizes are what decide whether a carburettor runs. A unit that bolts on and runs badly is the normal outcome of guessing.
Road legality where you are
Lights, mirrors, exhausts and brake parts face approval requirements that differ by market. We establish what the part actually carries before you commit.
Branded parts and replica bodywork
Replica fairings in a manufacturer's livery, and parts stamped with a known brand, are seized at the border. We check for it first.
Bearings and consumables by number
Wheel and steering bearings are standard parts with standard numbers. Buying them by number rather than by bike model is both cheaper and more reliable.
How an order runs
- Send the engine code and photographs The stamped engine code, plus photographs of the part with its mounting points and a ruler in frame.
- Platform and interchange established We identify what the engine actually is and what parts fit it, and say where a listing's compatibility table is simply copied.
- Numbers confirmed Chain pitch, tooth counts, bore sizes and bearing numbers agreed in writing before purchase.
- Quote and approval Itemised, with any approval or documentation issue stated rather than left for you to discover.
- Inspection with parts measured Sampled parts measured and photographed against the specification.
- Consolidate and ship Several sellers combined into one shipment, on a route that accepts the contents.
