Just after everyones honest opinion when to replace wheel bearings. I`m about to hit 20 000km and thinking of replacing them for piece of mind before my next trip. They do get a hard time fully loaded with gear and corrugated roads here in Aus.

Is there better recommended aftermarket bearings replacements rather than OEM etc heard of a few AT owners having problems.

For what they cost I'd simply go with the equivalent SKS and for their cost, buy a second set for 'next time'.

I think they're 6204rs...Honda OEM at a bike place here in UK...£17.68. Identical (probably higher quality SKS) from a bearing supplier...£4.41. It has 3 bearings so in the UK we'd save £40 buying from a bearing specialist over OEM.

Mine only lasted around 20k and you could see / feel movement in them (top of the wheel).
The Honda dealer said if you get 20-25k out of a set you're doing well.
Bike is ridden on gravel roads and through water.

FWIW I've done over 30000km on mine, and at last inspection they still seem to be fine.

Borrowed a SKF bearing catalogue from work and looked up the bearings required, only part numbers that are different are the 6204, Honda OEM Bearing is a 6204UU. Basically UU means double ultra sealed. I will get a set from my local SKF and see how much they cost.

Visited my local SKF and they had all the bearings I needed in stock, they are very easy to install.
First very important tip is heat the hub with a heat gun first other wise the bearings wont budge and you damage the bearing location removing the bearings, heat the hub just warm enough so you are unable to touch it and the bearings will fall out with a few light taps. I use a proper bearing installation tool but you would get away with a socket if your careful, simply reheat the bearing location and they will almost fall in. If you have time to spare put the bearings in the freezer over night and they will fall in with the hub warm . You need to set the wiper seal recessed 1mm. Some water proof grease and your GTG

My rear wheel bearing (brake side) failed at 23000 miles. I bought the extended Honda Care warranty when I purchased the bike (9/2017). The rear wheel bearings were covered by the extended warranty. The outer bearing race is difficult to remove once the bearing fails.

The attached pictures show what the bearing looked like once I removed the outer seal.

Kinda sad, I put 23k on my KLR650 and those bearings were good as new when I sold the bike - matter of fact the guys still riding on them with no issues...

This is good to know. I ride a lot of dirt and do some long camping trips. Thanks for the heads up.

Failed bearing last night heading to ferry in the UK; noticed a slight weave on the motorway and slowing up round a roundabout confirmed it. Looks like the seal on the bearing and the one outside of it had both failed letting crap in. 3.5 years old and around 13000km I think

Bearings are one of the few things that have a very long shelf life. I don't really track them by miles - but more by tire changes. If you are hard on tires, then you are probably also hard on bearings. Every 3rd tire change I'll have a set of bearings ready to go in - and unless they still look perfect I'll swap them out.

Sold my 2015 Triumph Scrambler (bought new) and it was still on the original bearings and it was ridden in just about all conditions. I've also read about someone with the new Scrambler 1200s that had a rear wheel bearing fail after under 1000km...I think things just keep getting made cheaper and cheaper unfortunately. I check for lateral play everytime I change tires, whenever theres a little play, replace.

I keep seeing more and more people doing stuff churning their rear wheel when their bike is up to the top of the wheel in water that looks like chocolate milk. I mean, how can you do that and not expect to ruin a set of bearings?

I run through water that makes it up to the axle - so I grease my wheels more often, use a good marine grease - and replace my bearings...

I guess it's time to do mine. I've got 50,000 kilometres on mine without an issue but it'll be part of my winter maintenance just to be safe.
