U/I can be a real btch. Had an LPO on my first ship order 10 boxes of Kimwipes. He didn't realize that each box contained 100 cartons and each carton contained 1000 Kimwipes.

We had engineers coming up to the shop to look for rags for wiping down their equipment.

25 dollars worth of bearings beats a thousand dollar headache.

I would be swapping them every 20k miles if not slightly less. They should be inspected often. If you live in or ride frequently in dirty, gritty environments bearing replacements should be often.

I had a similar experience with rear bearing failure on previous bike at 15k miles.

With the fonr wheel in the air and while spinning the front tire, everything was smooth and silent. Since I was about 800 miles from home at the time, I just kept going.

When I got home I lifted the front wheel again and it was still spinning smooth and silent.

Then I removed the wheel.

This fell out.

My rear bearing failure was bad enough it had chewed through the retention ring and some if not most of the bearings.

Invest in a bearing puller and seating kit, it pays for itself and isn't that difficult although I've not tried it on this bike (yet).

Keep some bearing replacements on hand too!

I've had Beemers that have gone well over 100K miles with the original front wheel bearings. And I know of some that have failed far earlier than that.

Thus I check the front bearings at every tire change to ensure they're clean and roll smoothly.

Yes, these are a "wear item" but a properly deigned and properly installed sealed bearing should easily last for 100,000 miles or more, even in a harsh motorcycling environment.

I had three full wheel sets (front & rear & tires mounted) for the last IBR. Two of the front rims had ~20K miles, and one had well over 100K miles. All three front rims had brand-new bearings and seals installed by me prior to the Rally, using a special seating tool made in my friend's shop that set the bearings square and concentrated the force on the outer races only.

None of the old bearings felt bad on the bikes, but some of them were just starting to show some stiction when turned by hand. In that case it was worth it, as a bearing failure there could have thrown away the entire 11-day ride.

But changing bearings as often as tires is just kinda silly. And if they're not put in correctly and carefully, then you're likely hastening their failure...

Some people see the gas tank as half empty. Some see it as half full.
All I care is that I know where the next tankful is coming from...

My K1600GTL front failed at around 35,000 miles. I started to feel some front end vibration only on turns. I would stop and check for vibrations or something out of place. Nothing... I initially thought I had picked up some trash because it was smooth when the wheel was straight and not under a load.

This is a discussion that I read with great interest, now I am very analytical and I looked at the photos and the videos on YouTube. I am looking for a common denominator or similarity that may have a trend.

What I saw was that the lock ring on most of the photos or videos had rust on it and that some most of the bearings had rust. Now I am not sure if I am on the right track, but do you clean your bike with a pressure washer like a Karcher or Wap? Because this may explain to me how the water got in there for the rust to form.

Myself do not wash with a pressure washer and after a service at the dealers I specifically ask them not to wash my bike, I will do it myself. To date I have never had problems with bearings on any make of all the bikes I had so far.

My 2008 BMW R1200 GS Adventure's universal had rust on it and in my mind it got the water in from the wash after services with a pressure washer....

I would consider the front wheel bearing to be a maintenance item that should be replaced around the 24,000 mile mark during a tire change and other maintenance.

Of the posts I've read over the years, the wheel bearings are pretty reliable to that point and probably further. But I think it's a safe bet they will have to be replaced at some point after that. So I would rather be ahead of that one and just replace them. That's my plan when I get to that mileage.

No pressure washer here, and I've had to replace bearings at ~25k and ~50k miles on my K1600. I just replaced front bearings on my XR at 24k.

The first set on the K1600 went from fine to nearly completely frozen in a couple hundred miles - destroyed the left side of the front tire and the right caliper brake pads. I was out on a day ride and started getting chatter in left hand corners, which got progressively worse as I limped the bike home. I change my own tires, checking the wheel bearings each time, so they were checked less than 2k miles before failure.

The others haven't been nearly as bad, as I caught them quicker, but one characteristic has been heavier brake pad wear on the side that wasn't starting to go, along with vibration / chatter / harder to hold a line in a long corner on the side that is starting to go.

Like @RedCard , I plan to change them every 24k from here on out. BTW, I've never had a wheel bearing issue on a non-BMW bike...
