That's only part of the story. The 67 refers to 67mm bore, but it doesn't tell you the stroke, therefore the final displacement is unknown. The second M in FMM means 250cc, but that's rounded up. There is no letter designation between 200cc and 250cc, so it's a crap shoot. If you decided to determine the stroke, we could do the math. It's likely to be 223cc.

Not concerned with cc, it is what it is thanks (223 I think your right)

So the nomenclature is a follows ?

1 - one cylinder?
67- bore of cylinder
F- ?
M- ?
M- 250cc class

F = natural air cooled
M = motorcycle engine
M = 250cc class

I trust Lifan to lable their engines properly but my Taotao ATV engine labeled 171FMM is actually a 163FML.
