But you knew I meant other than dealers right? :-)

The link is great, cheers.

Re: Rusty Headstock Bearings?
 

For that part? I'm not sure if there is an alternative to OE. If there is I'm sure somone will post to that effect, but the fact that you can't find one suggests there isn't.

Many consumables such as bearings and other standard parts are available as pattern or local source, but think about it - is that bit bike, (or manufacturer), specific? If it is then the chances of alternatives to OE reduce significantly, add to that the piece in question should last the life of the bike, to the best of my memory in all the bikes that I have waved spanners at I have never had occasion to replace one, it isn't a seal as such it's a cover.

You're welcome.
