Hi there. Anyone on the forum ever owned a Honda NSR 250 or 400? I would like to acquire one of these great relics of Honda history, but being unfamiliar with the models, I seek any guidance as to pitfalls or points to be wary of. Perhaps most importantly, is there a definite indicator to show that the bike is authentic and not a mock-up? In the meantime, I'll do my own research. Cheers!
