Subject: Re: reasons for bearing failure


Hi AT riders,
after having this bearing failure in Tuskany, I'm now always double
checking my rear wheel.
There are IMHO two reasons for the failure of the right rear bearing:

Cause 1:
the protective rubber ring, which avoids dirt comming to the bearing,
wears out quite quickly. Mine was ready to exchange after only
15.000km...   The little ring is just 12 DM at Hondas...

cause 2:
the original bearing has no real protection against dirt. There is only
one metal ring around the "balls". The bearings which are recommended by
Mr. Sakis have a own rubber protectiv ring on each side, protecting the
bearing from dirt even if the "outer" ring fails.

regards, martin
