I think the 400 used the same frame as the 600 so like most of the sport tourer Jap400's they were the ZZR-400 but they make a decent change if you didnt want the 600...
pity they don't give the option of bringing in the smaller ones over here. between 125 and 600 there isn't anything

I have seen and riden a RF400 (just briefly). Slightly smaller frame than the RF600 (which I own), a little more nimble and a little under powered. Motor is very quiet, compared to clunky 600, and controls are a lot smoother. I wouldn't own one, would be no good two up, however consider it would be a good learners.
