Two weeks ago installed new chain and sprockets at that time no wear or damage to bearing. Riders choice installed some new tires for me few days later this happens? ..... They don't see the connection.... Before I completely lose my s**t on them are they in anyway liable?

Started @135kph in express lanes. final catastrophic failure @60kph in posted 30kph off ramp. Man oh man was that close...

Did I mention I was riding 2up?
Best passenger ever! Anyone else and it would not have ended well.

Looks like they could have possibly forgot a spacer or got a bearing dirty and it seized, causing it to chew itself appart. Only way to know is take it apart and inspect. Inform them of the problem and they should make good on it. If not, BBB and then small claims.

That is so messed up. What did their service manager say? Glad you and your 2up survived. I hope they resolve this for you.
 
If the axle nut is correctly torqued and the tire replacement job did not include changing the wheel bearings then the shop is not liable in ANY way for this.

It looks like the outer spacers are there. The inner spacer is trapped inside the wheel between the two wheel bearings and cannot be removed without removing the wheel bearings, which is certainly not part of a tire change job. The seal on that side would not be disturbed in the process of changing the tire. That seal is obviously trashed now, but the tire job doesn't involve touching it other than sticking the spacer into it.

Coincidental failure. Deal with it.
 
Bearing failure. Can't see how you can 100% prove it was installers fault.

Bearing was ready to go anyways, proper chain tension + additional load from passenger + high speed = failure
 
Take with a grain of salt because i've only been riding for 4 years and have far from seen it all, but i dont think a wheel bearing should be failing on a 6 year old bike, not like that. If a bearing was that screwed they should be noticing that on tire install, but regardless you need to take that apart yourself before bringing it back so if they did something really stupid like forgot the inside sprocket spacer they cant cover their tracks.
 
I replace bearings all the time at work. There are many factors that affect bearing life. Radial or axial load, heat, RPM, time, quality etc. 6 years is meaningless without the other factors listed.I still say you can't hold them responsible.
 
I agree if the bearing just catastrophically exploded there's no way to prove the cause, and maybe it's just a bearing failure. I'm assuming for the time being its the bike under his avatar with the factory bearings still inside, so thats quality and time, and by RPM i'm assuming you mean speed. If the OP has been doing constant 200mph runs since the bike was new maybe, but i bet theres a bunch of 1000's running around Grand Bend with the factory wheel bearings in em that arent doing that. Thats a beyond bizzare failure on a 6 year old bike, i want to see all the pieces when it gets taken apart!

I've never owned a suzuki street bike, but yamahas have a needle bearing in the rear wheel and the inner race needs to be put in by hand, theyre not one piece. If the inner race isnt installed before the wheel, it would definately end up like that.

Age almost doesn't matter. Mileage matters more.

Has anyone, ever, in the history of the bike, possibly including prior to the current owner if they bought it used, ever used a power pressure washer to clean grime out of that area? That matters more. (Water pressure overcomes the seal, water gets in, corrosion starts, then it's only a matter of time.)

Rolling-element bearings have a rated lifetime depending on number of revolutions and on the applied load, and it is a statistical measure. Every once in a while, you end up on the short end of the bell curve. It could just be plain bad luck of the draw. Having said that, in this application, dirt and water ingress and misalignment due to improper installation of the wheel bearings (note: not the wheel - the wheel BEARINGS - the central preload spacer between the bearings can't be taken out of the wheel without removing the wheel bearings, which was not part of this job) will shorten the life of the bearing such that the rated life is not achieved.

When you replace these bearings, use the "...DD" type with double contact seals. The OEM bearing doesn't have integral seals on both sides (it relies somewhat on the external seal and for the spacer between the bearings). The double-sealed type are harder to screw up and it's one more barrier to keep lubricant in and keep water out.
 
great post ^ this forum needs a like button.
 
some one please correct me if I am wrong but...

should you NOT run the bike like OP is doing in the video after having known the fact that the bearing is gone...without the needles (or balls) the shaft would be riding on the outer race( I figure most likely bearing is a thrust fit) wearing out the axle shaft

If this bearing was wearing at a "normal" rate the bearings would have shown signs of needing replacement when the OP did the chain and sprocket install.

I would also be curious to know if the bearings were oem, or at least oem quality. I have installed some "all balls" wheel bearings and immediately removed them in favor of skf or NTN's.

I had a bearing go on my like this something like 10-12 years ago on a dirtbike.

I was going to mention that, but considering this happened at speed the axel is probably toast anyway. Running it certainly isn't making anything better tho.
 
Took it to Ted rose it took him all of 5 seconds to say chain was way to tight. I just never noticed. Could that cause such a failure?

Even if they didnt do anything wrong how could they have missed a worn out bearing? They let me leave shop like that. One way or the other this is not cool. I'll take pics of all parts and post when I get the bike back.

I personally have never used powerwasher on it and I've had it since almost new ( bought it at 4000km).

I've seen all kinds of bearings go and I've never seen one blow like this they always give some warning IE squeak or play.
