thanks to Andi - and all those who posted on this important topic - I'll be checking this bearing on my DR before heading South for the DB1K - cheers S

Bit of Loctite 641 Retaining Compound might help and/or add some peace of mind. I used it all the time for the bearings in my DR-Z250.

Around $100 for a complete set for the DR.

Mine was still going but getting worn at 40,000 miles , suzuki bearings only have a seal on 1 side but aftermarket bearings are sealed both sides , water is the biggest killer of bearings . The bearing in the sprocket will fail long b4 the other 2 bearings because it has a lot more load on it compared to the hub bearings.

Disc side bearing seems to be the problem one for me. I suspect because heat from the disc melts the grease - which then worsens the effect when it's dunked in cold water. Wheel bearings only spin at about 1/10th their rated max rpm at around 100km/h, so they (or their grease) aren't being stressed by that.

I hope Wonka Tractors gave ya a good trade in price for the old bearings ?

Just out of curiosity, what size are the other bearings in the back wheel ? Does the 650 have 3 bearings the same size ?
I get all my seals and bearings from Multiparts except for one on the front of the Big, which suzuki want $80 for

Toddy says they are all the same size which makes it easy, I can't confirm that however, seems the sprocket hub bearing is the one with the load on him.

I was gonna replace the lot but the two wheel bearings feel as good as new with no movement so they can stay there.

Loctite and the spacers, without the circlip have held it in ever since, occaisionally i have to re-loctite a new bearing in but has been fine, although I am waiting for a new hub to arrive from ebay.
I'm a bit paranoid about wheel bearings so i carry a set in my toolkit all the time now just in case. Poss over the top but getting trailered home was not a good look.

There you go.

Are they physically different sizes or what is the difference Nordie?

JATZ, they said they were out of warranty so they could not verify their condition without testing so no trade

, I did say well these two half bearings have been opened but nup they wouldn't budge, their loss

Same thickness but the 6205 has a larger inner and outer diameter.

most common bike wheel berring sizes...

6202 = 15 x 35 x 11
6302 = 15 x 42 x 13

6203 = 17 x 40 x 12
6303 = 17 x 47 x 14

6204 = 20 x 47 x 12
6304 = 20 x 52 x 15

6205 = 25 x 52 x 15
6305 = 25 x 62 x 17

Great info thanks Pete

Hope this helps many others who may inadvertently have a dud on the way without realizing it.
