I found an article some time ago on the XT660.com thread.

The chain drive sprocket takes a tremendous load from the power of the engine , which causes the rear wheel bearing to wear excessively , even wearing the Chain Drive Hub Housing ,
The bearing will become loose in the housing at a later stage,

I fitted a double row bearing as apposed th the std single *row bearing.
And with Polyurethane rubbers .I got 56 000km without changing the rubbers again.

You only have to machine the rear hub bearing housing 5mm deeper /
The Bearing I used is still the same dia. as the original.
And machine the inner spacer also 5mm shorter.
It still uses the Standard Yamaha Seal

Hi Hunday,
what size is the double row bearing? I only found one with 20x52x21.
If so, wouldn't I have to have mill 6 mm deeper and shorten the inner spacer 6 mm as well?

Regards
Marcus
