Age plays a part, although I was under the impression the NC24 was the VFR earlier model, NC25 was a Bros? Don't forget, Honda had loads of 400s, VFR, RVF, CBR, Bros, CB, to name ones I can think of. The ones which are "Grey" are imports, although I was always under the impression CBR's were always imports? You'll also need to take your time, because everyone had the same idea, bought them, run them without the maintenance knowledge in 90% of cases, and then flog it on. Always be aware that plastics are going to cost you about the same as the bike if you bin it
