Do you guys change these based on mileage, or wait until you have an issue? With cars I usually wait for symptoms to appear, but a bike has much less to fall back on.

I have about 28,000 miles on the Bandit. My sprocket carrier bearing is a bit dry, the wheels felt fine. Should I change all at the same time for safety or do the sprocket bearings wear out quicker due to the load? I'm sure theres a lot of preference, I just want to see what everyone else does for peace of mind.
 
Some bikes have sealed bearings, some have open bearing cages and some have a mix. I've seen the open bearings wear out prematurely because they don't get serviced the way they should be. Sealed bearings last longer but they still go bad.

They're not that expensive and it's cheap insurance to change them out during a routine tire change. All Balls makes nice sealed bearing kits that work well.

If I feel the slightest play or roughness in any of the bearings I change them all. On old bikes that have been weathering outside for years I change them all. You are only going to spend maybe $60 for a full set of bearings for a rear wheel and sprocket assembly, so why even think about trying to stretch a few more miles out of old bearings?
 
They are so inexpensive now, as stated thru All Balls Racing, complete kits with seals, etc.
I would and have done it just for piece of mind.
All Balls has really made it easy. Good guys too if you have a question, just call them.

Same here. I changed out the rears on my ZX6 at about 15k miles because there was a clicking coming from the back wheel in relation to wheel position, not chain. I think I paid about 60-75 bucks for the whole set, as others have stated. Took under an hour once I had the wheel out, and I was changing tires anyway so no big deal.

If you're going to do it yourself, be sure to drive the outer race, not the ball bearings or seals. Common mistake.
