    There has been some dicussion recently in regard to the 4-cylinder XJ400. The 398CC XJ400 was the first XJ, introduced as the "D" for the Japanese home market.

    I can't quite figure that one out, "D" would make it a 1977 by Yamaha's standard coding system and they came out only a year (two maybe) before the Seca 550 here (as far as I know.)

    Anyway, the first ones had the "Buck Rogers" pipes, which were soon replaced with ones more closely resembling the 550 Seca.

    The bike was also sold in Europe from '81 through '83 or so; and reappeared in '95/'96.

    I'd love to get my hands on one of the original ones with the rocketship pipes. Otherwise it's just a fairingless Seca 550 and I sorta have that covered.

    First time I have seen that, wow that is nice, what really amazes me is the fact that they put dual discs on the 400 but a single disc on the 550?? Interesting graphics on the first pic, almost reminds me of the gpz's

    Hmm...

    The four: 46HP at 10K rpm, 388lbs. dry, 14.0 quarter mile at 90.5mph, 101mph top end.

    The twin: 46HP at 9500 rpm; 373lbs. dry, 14.0 quarter mile at 92mph, no top speed listed. (This is the "XJ" XS twin, the DOHC like the 82 Seca 400.)

    I would say they're quite evenly matched; the twin gains a slight edge in speed (only) in the quarter mile probably due to the weight difference.

    They put dual discs on the EURO-spec 550s. The 400 got "cheapened up" later on with only a single disc.

    I'm pretty sure this is a Euro-market '83:

    The XJ400 was probably introduced as a result of the Japanese internal licencing system which exsisted up until the mid 90's. In 1976, Japan introduced a three-tiered motorcycle license system. A license for small bikes to 125cc, medium bikes to 400cc, and a third one with no displacement limit.

    This resulted in many 400cc variants of the models for the international market, some of which were also exported to other countries. I had an XZ550, there was also a 400 model which Yamaha dumped on the New Zealand market the year after they ceased XZ production.

    At that time, in Japan, wasn't there a maximum of 750 CC's AND a national speed limit of 50 MPH ??
    And when was this lifted ??

    On a totally different note- - in Japan, they name the intersections, not the roads !! Are there any Japanese XJ-ers out there??

    I'm not sure about the 750cc limit for the Japanese domestic market but given my XJ750E-II (Japanese domestic model imported into NZ) has a big red light in the middle of the instrument cluster which lights up at exactly 80 kph I'd assume that was the magic top speed limit.

    All my info, from the Vision Riders (XZ) Forum indicates sometime in the 90's.
