Chongqing Motorcycle Suppliers: Engines, Parts and Checks Before You Buy

Chongqing is one of China's biggest motorcycle production centres, with large brands, engine makers and hundreds of parts suppliers in the city and the surrounding districts. Other clusters make scooters and electric two-wheelers, notably in Guangdong (Jiangmen and Guangzhou), Zhejiang (Taizhou and Jinhua) and around Wuxi and Tianjin. A large share of the motorcycles, engines and kits sold in Latin America, Africa and Southeast Asia come from these places.

Buyers who lose money here usually buy from a real company. The problems are the specification: an engine that is not the one quoted, a frame with thinner tube, a brand look-alike that customs will seize, or a model that cannot be registered in the buyer's country. This guide explains what to check.

Brand, assembler, trader

• Brand manufacturers with their own engine and vehicle plants, catalogue models and export departments.

• Assemblers who buy engines, frames and parts and build motorcycles under their own or your brand. Quality depends heavily on which engine and parts they buy.

• Traders who buy complete motorcycles or kits from either and export them.

All three can be the right supplier. You need to know which one you are dealing with, because it decides who controls the engine, the parts and the warranty.

Registration and production qualification

• Check the company in the official business registry: scope, address, founding date, insured employees, court records.

• In China, motorcycle makers must be approved to build vehicles for the domestic market, and their models are listed in a government vehicle catalogue. Many export-only assemblers are not on it. That is not illegal for export, but it tells you what kind of company you are dealing with.

• Check whether the engine is made by the supplier or bought in, and from whom. The engine maker's name and engine model should appear on the engine casting and in the documents.

What to put in the specification

• Engine: maker, model, displacement, bore and stroke, cooling, power and torque, and emission level.

• Frame: tube material and wall thickness, and how the frame is welded and painted.

• Key parts: carburettor or injection, brakes (disc or drum, front and rear), tyres, battery, shock absorbers, wheels and chain, by maker and model where possible.

• Electrics: lighting, wiring harness and connectors, with the voltage of the system.

• Brand and design: your logo and design must not copy a registered brand or design in your market. Look-alike models are a common cause of customs seizures.

• Kits: for CKD or SKD kits, a complete parts list per kit, with packing per kit so nothing is missing at assembly.

Your country's rules

Most importing countries have homologation, safety or emission rules for motorcycles, and some limit the import of complete vehicles to favour local assembly. Confirm with your customs broker or homologation agent which documents and tests you need, and ask the supplier which of them they can provide for the exact model, with certificate numbers. Do not rely on "we export to your country" without documents.

Inspection before shipment

• Start, ride or run each sampled motorcycle: idle, acceleration, gear change, brakes, lights, horn and indicators.

• Check frame and engine numbers against the documents, and that they are stamped clearly and match your shipping list.

• Compare the engine, brakes, tyres and shocks with the agreed specification and the approved sample.

• Check paint, chrome and fasteners, and look for oil leaks.

• Check packing: crates, protection and, for kits, completeness per kit.

Questions to send the supplier first

1. What is your full Chinese company name and unified social credit code, and where is the assembly plant?

2. Who makes the engine for this model, and what is the engine model number?

3. Which brakes, tyres, shocks and battery are fitted, by maker?

4. Which documents and certificates can you provide for our country for this exact model?

5. Can we see this model being assembled and test-ridden on a video call, and inspect before shipment?

Chongqing is a direct high-speed train ride from Xi'an, where I live, and my own trade is electric motors, so I am at home in assembly plants and engine workshops. See also China's manufacturing regions and AQL sampling explained.
