According to this link
It seems the 1989-1993 VFR400 (NC30) and cbr250 are now legal imports to the USA.
I called RIV and they said What i would still need to get something from Honda stating the bike meets US requirments.
But besides that it shouldn't be a problem bringing in the bike and getting it registered.
I assume we could get a the bike in Asia as long as we get a letter stating it meets US requirements.
This could be interesting. Group buy anybody?
