Front Wheel Bearings - Which Are Best?

Just wanted to see what the current thought of the group was on front wheel bearings. As I have a new wheel coming to me, it seemed to me to be a good time to pre-emptively replace the bearings. What is the best choice for longest lasting/most durable wheel bearings? I'm willing to pay more to get better quality, and because I ride my 919 daily on some really crappy roads (note that other DFW riders have been eating entire wheels of late) I can certainly appreciate dependable wheel bearings.

I also have access to several industrial bearing houses in my general vicinity if they are a common bearing number and Timken, SKF, whoever, would be a better choice than some kit.

I have tried to find alternative sources and have been unable to. I think they are a very odd size (20X45X12), so OEM may be the only option. I haven't heard of anyone having their front bearings go out. I have almost 50K mi and the original bearings. I do have a set of OEMs on the shelf when the time comes though.

At 62K, I have yet to change the front bearings only the rear wheel bearings. I went with OEM.

Unless an inspection of the bearings reveals roughness or notching it shouldn't be necessary to replace them -- they are much less loaded than the rear bearings.

Trick, but not suitable for this application.

They are intended for extremely high rotational speeds with little in the way of lubrication. The Zirconia balls are considerably harder than case hardened steel of the more pedestrian bearings, but are very prone to shattering when subjected to shock loads.

Stick with OEM unless you can find SKF or Fafnir units.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

I have access to SKF, Fafnir as well as Timken units; if I can find the numbers, I can probably get them from those manufacturers.

Looks like the retail-no-discount price for the bearings and seals (two each needed) are $9.96 and $5.65. Not terribly expensive and evidently about as good quality as I am likely to find from what people here are saying, so this may be the way to go.

Just make sure they are not made in China.

Ah, I didn't make myself clear - that's the prices at the local Honda dealer for the actual Honda parts.
