Look what just arrived

Getting excited now! Any tips/tricks for removing and installing the wheels? I will have the dealer mount and balance the new Michelins. Thanks

I have my tires mounted at the local Honda dealer. He's cheaper than the local BMW dealer, go figure.

Are the front wheel bearings serviceable? Meaning, can the be cleaned and re-packed with wheel bearing grease? If so, How do they come apart? By removing the 5 allen head bolts?

First, are they stock wheels?

I know it's a R90/6

Take a picture of the wheels for a better answer.

Yes, the certainly are serviceable, and if as you say have not been serviced yet, they are in plenty need of it.

BUT, do not tear into them without first reading carefully how to remove them. Or have a qualified mechanic do it (and that may or may not be your dealer).

At 20k-ish original miles I would leave them alone and ride them until they need service.

If you're only messing with this one bike it'll be worth it to fork over the 100 dollars or so to have both of those mounted and balanced by the bike shop (as opposed to buying tire spoons and a wheel balance stand.) Make sure they use new tubes, even though the OEM ones are so much thicker than most of the crappy Kenda type ones made today.

You can still get heavy tubes.

I would suggest at least greasing the bearings. There is a tool that makes greasing the wheel bearings very easy and fast.

here is a link to it.

Have the tires mounted by a shop. Then you do the wheel bearing service.

You need a pin wrench to get the front wheel bearing hub off. Cycle Works still sells this tool I think. It can be done other ways but if you try to do it without the wrench you will damage the wheel hub. So get the tool.

You will need new wheel seals, front and back. If water has gotten into the wheels you may need new bearings but this can wait till you have the bearings out and can inspect them.

The rear wheel bearings come out in an entirely different manner. Either get the special tool for greasing the rear bearings from Cycle Works or learn to remove the bearings. This involves a heat source, most use a heat gun, I use a propane torch, to get the right side, captured bearing out.

Do you have a manual? You really should. This is explained in the Clymer's Manual with pictures.

Yep, leave the wheel bearing servicing til next tire change. The hubs have to be heated and the bearings driven out and the bearing preload (shims) checked. But yes, get the bearing greaser tool from Cycleworks and give 'em a shot of fresh grease.

Geez, 38 year old bike and we are debating whether or not to grease the wheel bearings?

If it had 1 mile on it I would want to replace the grease.

At the very least, you can get to 3 of the bearings without removing any races.

Absolutely agree. Mine had done only 6000 miles in 28 years and the grease had partly dried up. I also don't get this thing about driving out stacks when all you have to do is remove all 4 grease seals. Checking and setting the preload is another thing and probably beyond his scope but you still don't need to drive out the stack to do a far better job than the factory did.

For me it's a perfect opportunity to balance a wheel on it's own thoroughly cleaned and lightly oiled bearings minus seals. You don't need a wheel balancer to do good sensitive balance on clean bearings.

I've always cleaned my bearings before greasing them. I have Lesters and the difficult bearing is removable. I opened up the seal area very slightly and I can move the bearing to a sideways position and take it out. I never understood why BMW didn't do that, but maybe it's a money in the dealer pocket thing. The stock seal is a bit loose so I use a few wraps of teflon tape.
