I just picked up this NC30 on Saturday. I drove all day to get it. The seller was kind enough to make a 3 hour round drip to shorten my round trip drive from 13 hours to 10.
For those not familiar with this model, they were never officially imported to the US. They were sold mostly in Japan, and some limited numbers of them were sold in the UK and other European countries. Titled examples are very rare in the US. The NC30 is the "baby brother or sister" to the rare/expensive RC30 VFR750R. Some of them even had the same red/white/blue color and graphics of the RC30.
It is wonderful to ride, so light and flickable. Yes, for what I paid for it, I could pick up any number of more modern, more capable 600cc sport bikes, I just love the V4's character. I also don't need the performance of a 600. The little 400cc V4 is more capable than you'd think for such a small engine. I do need to get a different muffler though. The stock Honda exhaust is typical Honda -- way too quiet.
