Or somebody in its checkered past has fitted a different wheel
Wheel was from an ultra-low mile US original and definitely untouched. Pretty convinced Honda changed the lacing pattern during later production now ... grrr
Update : just found the -305 parts are for very early bikes and around 175mm long compared with bikes after frame 142498 which are about 195 mm and -301 parts . I just need to establish which NOS rim I have as that changes too.
WARNING to anyone thinking of restoring an S90 .. the parts changing are an absolute nightmare
