Wheel bearings

Ok you smart, clever lot. Especially those who have swapped a back wheel. Pete, what did it come off? 750 or 1000?
I have looked at the site and got both sets of destructions on changing the wheel, however the wheel bearings are different. The FZR 750 ( I think thats what it is ) are a wider diameter than the TRX, but have a larger axle hole. Just to confirm the TRX bearings wont fit into the 750 wheel, ( because they're too small! ). Any numbers for the bearings you used, or what other mods did you do?
I am going to a bearing warehouse tomorrow in an effort to find ones that fit.

Dave

is that the wheel I sold you about 3 years ago - are you only just getting round to fitting it?

It came from a YZF750 btw

at a guess 20mm id x 52mm od x 12mm wide which is a pretty rare beast

The very same Pete, been busy with the house. Need a new rear disc, so thought I would try the bigger wheel first.

Martin I am going to a bearing wholesalers tomorrow so will find out how rare they are.

If not I will get the FZR wheel and get that to fit.

Is the FZR 600 rear wheel the same size as the FZR 750 rear wheel?

Think you'll find the FZR 600 wheel is a 5 inch therefore a 160 tyre: same as TRX.

20 x 52 x 15 is the nearest bearing I can get. thinking if it will make a difference having wider bearings. Any thoughts?

will the wheel fit in the swingarm with the wider bearings in?

would you be better off using the YZF bearings and fitting a sleeve?

Are you thinking of a sleeve over the axle?

Here's a very useful site for bearings...

Codger,

If the FZR/YZF/whatever wheel has a bigger spindle dia, why not get some 'Top hat' spacers made up? If you can get me some dims I may be able to help you out....

Bearings I can get no problem, which was how I was able to find out the nearest size. I may take you up on the top hat spacers/sleeve? Thanks for the offer Ady, will let you know when I get 5 seconds to measure up.
