If changing front wheel bearings, it's no different to most other bikes.
Remove any outer oils seals is present & heat up the hub on one side. I used to use a small gas torch but used a hot air gun with good results at the weekend when fitting new paralever bearings to my 1150.
You'll then need a long screwdriver or similar to catch the edge of the bearing & drift it out from opposite side. Remove spacers & knock remaining bearing out from the other side.
Clean hub, heat one side & tap new bearing in, making sure it's square at all times, Use a drift if you can, with an OD slightly smaller than that of the bearing.
Install spacers etc & install other bearing as above.
Tip: if you have a Mig welder, you can cut/file a small strip of steel to size & weld it to the inner bearing track on one side. Using a long drift against the steel strip, tap it out from the other side. There should be enough heat left in the hub to also knock the other bearing out. This works well when an bearing race has disintegrated leaving only the outer track & where normal methods won't work.
