Cfmoto 400nk
The Cfmoto 400nk has a top speed of 155 km/h (estimated; note: unverified official figure, based on owner reports), produces 42 hp and weighs 179 kg. Motoryk rates it 7/10.
The CFMOTO 400NK was introduced around 2019 as part of CFMOTO's NK (Naked) middleweight street fighter lineup, designed to compete in the growing budget-friendly naked bike segment in Asia, Europe, and Australia. It shares its platform and parallel-twin engine architecture with the 400GT and is closely related to the 450NK that followed, reflecting CFMOTO's push toward more refined, internationally competitive motorcycles. The 400NK became notable for offering strong value-for-money with a modern twin-cylinder engine and aggressive styling at a price point well below Japanese and European competitors.

What Buyers Should Know
KTM-Derived Engine
The 400NK uses a single-cylinder engine developed in partnership with KTM, giving it a pedigree that rivals more expensive European naked bikes. This collaboration generally results in solid engine reliability for the price point.
Watch Electrical Components
Some owners report issues with electrical connectors and switches corroding or failing prematurely, particularly in humid climates. Inspect wiring harness connections carefully and budget for potential minor electrical fixes.
Steep Depreciation Curve
CFMoto bikes depreciate faster than Japanese or European brands due to lower brand recognition in Western markets, which actually benefits buyers purchasing used. You can find well-maintained examples at significantly reduced prices after just 1-2 years.
Generations & Specs by Year
Initial launch with 400cc parallel-twin engine, tubular steel frame, USD forks, basic LCD instrument cluster.
Revised bodywork styling, updated TFT color display, revised suspension tuning, improved Euro5 compliant engine calibration.
Used Buyer Review
"Solid budget naked if you buy post-2021 and inspect carefully."
$3,500-$5,500 usedThe 400NK is one of those bikes that surprises you once you stop comparing it to Japanese alternatives. The 400cc parallel-twin pulls cleanly from low revs, the suspension is genuinely compliant for urban riding, and the fit and finish on post-2021 models is noticeably better than the early stuff. Used examples are cropping up everywhere now, and honestly, the value proposition is hard to argue with if you're budget-conscious. That said, go in with eyes open. Parts availability is improving but still patchy depending on where you live — dealer network is thin outside major cities. The stock exhaust sounds agricultural, and budget riders tend to leave them bone stock, so inspect carefully for cheap mods. Electrics on pre-2021 models had known gremlins; check the instrument cluster and indicator relays specifically. For a newer rider wanting a proper-looking naked without destroying their finances, it makes real sense. Just don't expect Kawasaki Z400 refinement — this is a different proposition entirely, and at the right price, a genuinely decent one.
