A dealer forwards three screenshots in one message: a Kazakh marketplace listing for a “ZTOT Z7 Max NB300 ZS174MN”, a Russian listing for a “ZTOT Z7 PRO NB 300, 2026” rated at 28 hp, and an Instagram search snippet for a “ZTOT Z7 MAX XFH300” described as a two-stroke with 35 kW peak power. Three names, three power figures, and only one of them matches the bike FCDC Motor publishes. Sorting that out before a quote leaves your desk is most of the job, so here is the map: names, engines, and the fields to lock.
The bike behind the name we publish
| Field | Published value |
|---|---|
| Brand, series, SKU | ZTOT, Z7MAX, ZTOT-Z7MAX-NB300 |
| Engine | ZONGSEN NB300, single-cylinder, four-stroke, water-cooled, overhead cam |
| Displacement | 279.6 ml |
| Maximum power, torque | 19 kW at 8,500 r/min; 24 N.m at 7,500 r/min |
| Dimensions, seat, clearance | 2,210 x 820 x 1,260 mm; 920 mm; 300 mm |
| Fuel tank, curb weight | 11 L; 118 kg |
| Tyres | 90/90-21 front, 120/90-18 rear |
One mismatch on the ZTOT Z7MAX NB300 product page is worth flagging. Its SEO title reads “ZTOT Z7-PRO NB300 280cc”, while the SKU on the same page is ZTOT-Z7MAX-NB300 and the series field says Z7MAX. The SKU and the specification table are the identity here; any screenshot that shows the Z7-PRO title is an old label, and any quote must be built from the SKU, not from the label. The page’s feature text also names the Zongshen ZS174MN-5 engine, which is the code the Kazakh listing shows.
Fourteen variants, one naming system
The product sitemap lists 14 ZTOT dirt bike variants: Z6MAX on YBS300Pro; Z7L in NB300, PR300, YB300H and YBS300Pro; Z7MAX in NB300, YBS300Pro and a cradle version of YBS300Pro; Z7X in YB300H and YBS300Pro; Z8L in NB300; Z8MAX on YBS300Pro; Z8X in YB300H and YBS300Pro. None of the 14 has an editorial guide, only a product page, so the naming has to be resolved in the quote thread rather than in a brochure.
| Name as sold | Engine suffix in our sitemap | What to confirm before quoting |
|---|---|---|
| Z6MAX | YBS300Pro | Which body kit and accessories ship on the YBS300Pro build |
| Z7L | NB300, PR300, YB300H, YBS300Pro | Which of the four engines, because the suffix is the engine |
| Z7MAX | NB300, YBS300Pro, YBS300Pro cradle | Standard or cradle build, plus the engine code in writing |
| Z7X | YB300H, YBS300Pro | Engine code and the trim level behind the X |
| Z8L, Z8MAX, Z8X | NB300; YBS300Pro; YB300H and YBS300Pro | Family, engine code, then whether parts interchange with Z7 |
Why 27 or 28 hp and 35 kW are different bikes
Start with the figure we publish. The Z7MAX NB300 page gives 19 kW at 8,500 r/min. Converting that, 19 kW is about 25.5 hp, or 25.8 PS on the metric scale; that is arithmetic on the published kW figure, not a factory horsepower rating. A listing that says 28 hp is claiming roughly 20.6 to 20.9 kW, a step above the page. The Instagram search snippet that advertises an XFH300 with 35 kW and 48 hp does not agree with itself either, since 35 kW converts to about 47 hp, and we treat that snippet as an unverified seller claim. And that reel describes a two-stroke, while the NB300 page describes a single-cylinder four-stroke.
So the market is trading at least three machines under one family name: the NB300 four-stroke, an engine-code variant sold as Z7 PRO, and an XFH300 two-stroke with a much larger power claim. FCDC Motor does not sell the XFH300 two-stroke. Our ZTOT page is the NB300 four-stroke, and if a buyer’s screenshot shows a two-stroke at 35 kW, that is a different bike and must not be quoted from our NB300 numbers.
The SKU lock list we use before a quote
Six fields settle it, and we ask for all six in writing: family and SKU, engine code, seat height and tyre sizes, accessories packed with the unit, the document set for your destination, and the quote basis of port, quantity band and packing. The document question is not one we answer for you; the certificates page holds our business license, and product documents are confirmed per model and destination before quotation, with your broker on the compliance side.
From the Export Desk: a screenshot is not an order line. We ask for a photo of the engine case and the catalog page behind the listing, because the same family name ships with four engine suffixes and the plastic on a Z6MAX does not tell you what sits in the frame. When the sample unit goes out and the first container follows, spares are keyed to the engine code rather than to “Z7”, so a top-end kit for an NB300 is never packed against a YB300H. In the sample order to wholesale sequence the prepaid ladder runs on that same locked SKU, and at loading the units are checked against the parameter sheet code by code, with crate counts read off the loading quantities by model plan rather than from memory.
What this means for stocking
Do not assume the Z7L NB300 and the Z7MAX NB300 are the same motorcycle with a different badge, even where the engine suffix matches: they sit in different families, and the plastic, frame detail and parts list have to be confirmed per family before you plan a parts line. Narrow is safer than wide: one engine family per shipment keeps your spares shelf readable, and the ZTOT brand background is the place to start if your buyers ask where the range comes from.
Fourteen variants with no editorial pages also means the naming is being explained to buyers by marketplaces, in three languages, with the numbers drifting. That is where the 27 hp and the 35 kW come from. Your fix is not an argument on the internet, it is a quote sheet that carries SKU, engine code and the exact specification rows, so the buyer can compare like for like.
FAQ
Is the Z7 Max NB300 a 250 or a 300?
The page states 279.6 ml. Sellers round it to 280cc, and the page title says 280cc while the SKU says NB300. Quote from 279.6 ml and let the engine code do the identifying.
Which engine code should appear on the quote and invoice?
ZONGSEN NB300 for the bike on our product page, and the feature text names the Zongshen ZS174MN-5. Put the code on the quote so the shipment can be checked against it at loading.
Do you sell the two-stroke Z7 Max XFH300?
No. Our ZTOT page is the NB300 four-stroke, and FCDC Motor does not list an XFH300 two-stroke. If a listing shows 35 kW and a two-stroke engine, it is a different machine from the one we quote.
Send the screenshot, the destination port and the quantity band through Get Quote, and the reply comes back with the SKU, engine code and specification rows filled in, so the next conversation is about parts and documents instead of names.
