1090 RR Wheel bearings

Hi all

Just taken the front wheel out of my bike for the first time and the bearings feel quite knotchy to say the least , can anyone advise on any particular brand i should be replacing with ?

Any tips for removal of the old ones would also be appreciated , i asume the size i require will be on the bearing .

Not very impressed with the quality at all - took the front out of my 04 Bonnie also this afternoon and the bearings felt brand new .


Any advice welcome .

Thanks

Steve

Either carefully knock them out with a long drift punch, working around the perimeter or use a proper bearing puller.
Alternatively, heat can be used to expand the wheel away from the bearing so it "falls" out.

Bearing size and type should be on the outer race. You can also measure the ID -OD and width and go on a search.

Spend some serious money and get ceramic bearings.....then you can brag about them, even if you don't realize any street use benefits..

But The Knurl will have better information on bearing grades and other R&R methods.

I used to be fast....now I just dream about it.

Original bearings are imprinted with 'made in France' they were crap. 8000km iirc. Replaced with generic, probably Chinese. Up to 40,000 km now with no further issues. Go figure.
It is a lot easier if a proper bearing puller is used to remove them.

PM me

Ed;
I wouldn't use heat......probably ruin the paint on the wheel

Jon;

The front bearings on my 1078 felt notchy at a low mileage,and a further check I discovered it was the centre spacer being too long putting too much load on the bearings.Slight machine off the spacer and all was fine.The bearings were perfect,the load by the spacer was giving a false indication that the bearings were notchy.

Are you saying that the length of the spacer is greater than the distance between the seated bearings ?

If so by how much ?

Either way i assume i will still need new bearings .

Yes,the lengths of the spacers seem to be inconsistent,mine was 1mm too long and some are too short.Use your bearing puller to move out 1 bearing slightly and re-check the 2 bearings for smoothness,you might get a surprise and see the bearings are quite OK.Just trying to save you spending money when you don't have too.
