Can't find details of this bike anywhere ..... it's not an XZ550 as reported.
Any one know what model it was?
I think that would have been a 550 Seca in the US.
Based on the caption "Lord Lichfield....", I suspect it may have been a UK bike.
I think its an xj550 which had a chain rear drive where as bigger xjs 650, 750, 900. Were shaft driven. Ďave.
Thanks for the replies, XJ550 Seca seems to be it. Had a 6 speed box as well, pity the XZ Vision.
