Rear disc brake (debatable) is one upgrade people would prefer (we have had this argument before with dual-sports--rear disc vs. drum). The KPX has upside down forks is another. Again, debatable as to how 'necessary' they are.

Lifan does have an actual warranty, but if you aren't buying from a brick-and-mortar dealership, you will have to have the parts shipped to you.

The Honda is a good choice over any Chinese bike as far as warranty goes and resale, but one has to resign themself to having a smaller engine which may or may not matter to some people; as you indicated, this is not an issue for you.
