Don't go to a motorcycle spares shop with that part number
Instead go to an engineering suppliers or bearing specialist and order 6204 2RS. These will have rubber seals to keep the grease in and the muck out

If you are going to use Simply Bearing then specify a named brand such as SKF. Their classification "Brand / Quality: EU Budget - Economy Quality" does not imply that the bearings are of EU or european origin. I bought some a while back and on querying the quality was advised by them not to use them in safety critical applications such as wheel bearings.

You get what you pay for and if you use the sealed bearings you can fit and forget which has to be worth something.

Cheers

I would buy the bearings with specified BSA part number from a reputable BSA parts supplier to be sure they are of the correct quality for a motorcycle wheel bearing and that the grease sealed within them is also fit for purpose. Given that there are only two bearings in the wheel, you want to be absolutely sure they aren't going to fail when you are travelling along the road at high speed!

What guarantee have you that a dealer will supply superior products?
If I order from Simply Bearings or any other supplier I can specify the manufacture of the bearing. If the bearing is ordered from a spares dealer, the bearing will be whatever the dealer buys in, it could be anything

There is no way that a dealer will have bearings made with "special" BSA wheel bearing grease

You need to be sure the sealed bearings are suitable for a motorcycle wheel hub, especially the grease. As said, if you go to a reputable BSA parts supplier, you can have a reasonable level of confidence that the bearings will be suitable.

Not wishing to go round in circles but...
A parts dealer is going to buy bearings from a bearing supplier or wholesaler like Wassell who will buy from a bearing supplier.
If you buy the bearings from the supplier yourself, you can specify the manufacturer, the fit (std or C3) and the type of seals (none, rubber or metal)
If you buy from a parts dealer you do not know what you will get it could be a good make or something made in a Chinese sweat shop from recycled chopsticks
