At only 32.000kms the right hand rearwheel bearing gave up in a sudden spectacular "blow-up" shooting out the steelballs at the car I was overtaking at that moment.
The design of this assembly provides for no simmering or anyhting that can protect the bearing from rain etc...you can actually see the RH bearing directly...and relaying on the ball-bearings own built-in seals ( 2RS) is simply not enough. Also I suspect the bearings to be low-quality chinese bearings on top of that : they have no international markings on them (ISO) but are marked with HD9278 and F-559019.
Nevertheless having measured the bearings ( both sides are identical ) the ident is 6205-2Z ( or 2RS) and dimensions D52xd25x15.
Actually for a bike this heavy..and built for longdistance....the bearings are, regardless of quality, too small.
I've now fitted SKF quality bearings AND added a Simmerring at the RH bearing ( the one at the discbrake, very exposed).
