Micha;
I think the tube needs to be the length it is from the factory. I say
this because if the bearings don't have the preload obtained with the
"short" factory tube there will be "play" in the hub that will wear the
hub out of round. When this happens then the wheel will "wobble"
and cause further problems. Bearings of the type in the @ wheel
are meant to have a little bit of "preload" and that's why Honda
makes the tube like it is. If it were only one bike that had a shorter
tube, then it might have been a mistake, but as all of them seem to
be short the I'm sure Honda designed it the proper way.
If there are some people that are having bearing problems, I would
suggest looking for the cause elsewhere. Lubrication, pressure
washing, over-tightening the axle nut, dirt, all will cause bearing
failure, and these things should be checked first. There is no
need to assume the engineers made a mistake just because
some of us have had problems.
