Which GY6 variant, not which brand
A 50cc short-case and a 150cc long-case share a name and almost nothing else. We work from the engine case markings and the mounting centres rather than from the scooter model.

Scooter parts
Last updated
Most Chinese scooters share a small number of engine platforms — the GY6 family above all — and parts interchange across brands that look nothing alike. The badge on the bodywork is the least useful identifier on the bike.
What identifies a part is the engine variant, the case casting number and the mounting pattern, and those are the things we establish first.

What we check before you pay
Variator, rollers and clutch weights
CVT parts are specified by outer diameter, roller weight in grams and belt width. Getting the roller weight wrong changes how the scooter rides even though everything fits.
Belt dimensions, all three numbers
A drive belt is length, width and angle. Two belts with the same length and different widths will both fit and only one will work properly.
Plastics are model specific and rarely interchange
Bodywork is the one area with no platform commonality. We match on photographs of the mounting tabs, not on the model name, and we expect colour to differ slightly between batches.
Batteries and anything with a cell
Lithium batteries and units containing them restrict the routes available and need their own documentation. We flag it before quoting.
Brand badges make it a counterfeit
A part carrying a manufacturer badge or a well-known aftermarket brand's name is a counterfeit and is seized. We check first and will not buy it.
How an order runs
- Send photographs of the engine markings The case casting number, the engine number, and a photograph of the part with a ruler in frame. These beat any model name.
- Platform identified We establish which engine variant you have and which parts interchange with it, and tell you where the listing's compatibility claim is wrong.
- Specification confirmed Roller weights, belt dimensions, mounting centres and thread sizes agreed with the seller in writing before purchase.
- Quote and approval Goods, our service fee, inspection, consolidation and freight, itemised, on a route that accepts whatever the order contains.
- Inspection with parts measured Sampled parts measured against the specification and photographed, including the markings.
- Consolidate and ship Scooter parts come from many small sellers; combining them into one shipment is usually most of the saving.
