CFMoto 450NK and 800MT Maintenance: Oil km and Manual Split
CFMoto 450NK oil at 1,000 km then 5,000 km / 3,000 mi, 10W-40 JASO MA2. 800MT US books print 5,000 km oil; some markets print 15,000 km. Open your book.
How often should I change CFMoto 450NK oil?
The CFMoto 450NK US manual (2023) replaces break-in oil at 1,000 km / 600 mi. Periodic oil and filter are 5,000 km or 3,000 miles, whichever comes first. Severe use shortens the interval by 50 percent. Spec is SAE 10W-40, JASO MA2. Capacity on that sheet is about 2.5 L. No car oil.
That skeleton is the 450NK / 450MT family. Open the book that shipped with your Turkish VIN. Do not mix mile and km columns.
| Model | First oil | Periodic oil | Oil type |
|---|---|---|---|
| 450NK | 1,000 km | 5,000 km / 3,000 mi | 10W-40 JASO MA2 |
| 800MT US | See book | 5,000 km / 12 month band | Your sheet |
| 800MT some markets | See book | 15,000 km oil row exists | 790-class spacing |
Is 800MT service the same as a 450NK?
No. The 800MT is a 790-derived twin. Intervals are wider than a 450NK, but the copy depends on market. US Ibex 800 books print 5,000 km / 12 month oil. Rest-of-world summaries often show 15,000 km oil and 30,000 km valves. Read the cover of the book in your tank bag. Do not paste 15,000 km onto a US bike or 5,000 km onto an EU copy without checking.
800MT valve summaries sit near 30,000 km / 18,000 mi. The 450NK valve row is tens of thousands of km, not every oil.
Is CFMoto expensive to run, and are parts available?
Oil at 5,000 km is tighter than many Honda 10,000 km nakeds. The real cost in Turkey is dealer density and waiting on bodywork or electronics. Not “no service.” Short interval plus logistics. Home oil in warranty starts a paperwork fight.
Chain, tires, and filters still shorten in dust. 800MT adventure tires and chain sets cost more than a 450NK because they are larger.
Is it worth buying beyond the oil row?
On used bikes, look for stamps, software updates, and cover screws. The dash service reset is a long ENT hold in the book. Changing oil without a reset wrecks the reminder. Campaigns live at the dealer network.
This article does not invent catalog hp. The buying question is kW, parts, and which manual you actually have.

Frequently Asked Questions
How often do I change 450NK oil?
First at 1,000 km, then 5,000 km or 3,000 miles. 10W-40 JASO MA2. Halve it in severe use.
Is 800MT oil 5,000 km or 15,000 km?
Market split. US copies print 5,000 km. Some world copies print 15,000 km. Read the Turkish book cover.
What oil does it take?
450NK: SAE 10W-40 JASO MA2. 800MT: that bike’s viscosity row. No car 5W-30.
Is CFMoto maintenance costlier than Honda?
450NK oil is more frequent. Parts wait and labour network may be thinner than a 125 Honda. Logistics, not the litre, is the story.
Is 800MT service the same as a KTM 790?
Related engine family. Bodywork and CFMoto rows are not a 790 book. Do not copy KTM km onto a CFMoto.
What if I skip the first service?
Break-in oil holds metal. Skipping 1,000 km oil is how warranty arguments start.
