Zonsen AMT Motorcycles: What US Buyers Should Check
Venom Motorsports USA is preparing a Zonsen motorcycle range that includes planned AQS250, AQS401 and AQS628 models. For buyers interested in AMT, the first check is the exact transmission variant. The supplier catalogue lists both MT and AMT versions of the AQS250 and AQS628, so a model name alone does not establish which transmission is fitted.
This preview explains the factory reference information currently available. It is not a notice of USA stock or an offer at a confirmed price. Final equipment, availability and order details need to be established for the motorcycles Venom will supply.
Why the model name and transmission must be checked together
AQS250 and AQS628 identify model families. MT and AMT identify different versions within those families in the supplied catalogue. A purchase description should make both clear.
This is more than a naming detail. A buyer specifically seeking automated operation needs an order that identifies that version. Do not assume every photograph, colour or listing under the same model family refers to the same transmission.
The supplier’s online AQS628 listing also separates MT and AMT configurations. Factory reference material is useful for comparing the platform, while the final Venom listing must identify the actual configuration being sold.
What the catalogue confirms about AQS250
The supplied Zonsen catalogue lists a 250 cc engine and separate MT and AMT versions. It identifies the AMT engine as KEV250A and describes an AMT 2.0 shift system. The listed engine configuration is a liquid cooled twin cylinder, four stroke design.
The table gives the AMT version a catalogue curb weight of 183 kg, compared with 175 kg for the MT version. It lists a seat height of 725 mm and a fuel tank capacity of 16.5 litres. These are factory reference values, rather than measurements taken from a delivered Venom USA motorcycle.
For a buyer, the different listed weights reinforce why the exact version matters. It would be misleading to take the lighter MT weight and present it as the AMT specification.
What the catalogue confirms about AQS628
The catalogue lists the AQS628 with separate MT and AMT versions and identifies the AMT engine as KEV600A. Its listed displacement is 578 cc. The model name should not be rewritten as an assertion that the engine is 628 cc.
It describes a liquid cooled twin cylinder, four stroke engine. The table lists a curb weight of 210 kg, a seat height of 720 mm and a fuel tank capacity of 17 litres.
Those figures describe a different platform from the AQS250. A slightly lower listed seat does not establish that the larger motorcycle will be easier for a particular rider to support or move. Consider the complete dimensions, weight distribution and individual fit.
Factory reference comparison
| Detail | AQS250 AMT | AQS628 AMT |
|---|---|---|
| Listed displacement | 250 cc | 578 cc |
| AMT engine designation | KEV250A | KEV600A |
| Listed curb weight | 183 kg | 210 kg |
| Listed seat height | 725 mm | 720 mm |
| Listed fuel tank capacity | 16.5 litres | 17 litres |
Source: supplier supplied 2027 catalogue, printed spreads 33 and 34 for AQS250, and 27 and 28 for AQS628. Catalogue values are preliminary references for the planned range. They do not establish final USA equipment, availability or performance.
Where does AQS401 fit?
AQS401 is also part of Venom’s planned range. Its detailed specifications are not included in this preview because the matching technical information has not yet been verified. It should not be assigned an engine displacement, weight or control system by borrowing figures from another model.
That leaves buyers with a clear distinction: the name is part of the current plan, while a complete comparison needs its own confirmed specification. Final model listings should make that information available before customers rely on it to choose or order.
Questions to resolve before a future purchase
- Which version is being supplied? Confirm AMT or MT on the final listing and order.
- How does that AMT system operate? Request the actual operating instructions, including fitted controls and available modes.
- What is the final USA specification? Check equipment against the motorcycle being offered, rather than assuming every catalogue feature carries over.
- What is included in the offer? Confirm price, delivery arrangements and any preparation requirements when the sales listing is available.
- How will ownership be supported? Review the applicable warranty, service requirements, diagnostic arrangements and replacement parts information.
A catalogue preview cannot answer every ownership question. It can, however, make the later discussion much more precise by identifying the version and the reference figures that need confirmation.
AMT should be evaluated as part of the complete motorcycle
Transmission automation is one feature in a larger buying decision. Use your intended riding, physical fit and ownership expectations to decide what to compare. Engine size and seat height should be considered together with the rest of the platform.
For the currently listed range, Venom’s automatic motorcycle collection remains the place to check live offers. Those motorcycles should not be relabeled as AMT unless their own specifications establish that technology. For questions about the incoming Zonsen range, contact Venom Motorsports USA and ask about the exact model and version.
Common questions about the planned Zonsen range
Are all AQS250 and AQS628 motorcycles AMT?
No. The supplied catalogue lists MT and AMT versions. Confirm the exact version rather than relying on the family name.
Does AQS628 mean a 628 cc engine?
No. The supplied catalogue lists its displacement as 578 cc.
Can I use these figures as final USA specifications?
No. They are factory references for the planned range. Use the final Venom USA listing and order details when available.
The strongest purchase starts with a clearly identified motorcycle. Confirm the model, transmission version and final specification together, then evaluate the support and ownership information behind the offer.
