From my experience, the standard of the spoke quality on the ACE would not be as good as the Japanese equivalent, as I've had two rear spokes fracture within warranty, and it has made me wary as I constantly check the spoke tension on both wheels to ensure all is well.
From new, both wheels displayed a slight wobble, and experience with a previous Honda C-90 has made me very adept of using a spoke key to ensure that the rim runs straight. (There are some really useful You-Tube videos giving excellent tuition on this) As all UK riders would know, avoiding major pot-holes whilst riding is becoming a national sport!
