I rode my 2003 Yamaha FJR1300 for about 10K km all over Europe. On my way back home a loud cracking noise came out off the rear wheel. So it appeared that rear (and front) wheel bearings needed to be replaced.
Having no special tool for bearing extraction, I tried several methods of pulling/knocking these bearings out of the wheel. The method that finally worked out was to make use of a 20mm anchor bolt mounted into one bearing at a time.

The anchor and the new bearing:
Mounting and tightening the anchor bolt in one of the old bearings still in the wheel:
Once the bolt is firmly mounted in the bearing, put a steel shaft from the other side of the wheel through the axle opening and knock the old bearing together with the anchor bolt out of the wheel.
Now mount the anchor bolt in the other bearing and drive it out of the wheel using the same method.
This fantastic tool - the anchor bolt, could be purchased at a hardware store for a couple of bucks. Since they are not intended to be precise, it's best to take a new bearing with you to a hardware store and choose an anchor bold that is best fit for the purpose.
As your bearings are out, it's time to press-in the new ones. Unless you own a pressing machine, you are likely to use a hammer to drive new bearings into wheel hub. I found it convenient to use a short cut of a plastic water pipe fitting or appropriate diameter as a driver. Make sure to apply force only to the outer racing of the bearing.
