Bearings Bloody Bearings?

I've just had my 910s in for its 18000km (12000 mile) service. No problems with the service itself, but they had to replace the twin race bearing in the hub and charged me €300 for the privilege. I also had it replaced at 9500km also for €300! I wasn't expecting the bearing to go so quickly or cost so much, and these prices are excluding labour costs!!
I'm wondering if it's possible to obtain a cheaper and better bearing that I could fit myself?
I would love to upgrade to a Mitchy hub, but sadly don't have the finances to do so, especially as my wife also has a Brutale.
Sharon's (my wife!!) Brutale S has done 8500km, so I'd like to inspect the hub and change the bearing if necessary.
Should I also replace the two seals or just the bearing? What grease do you recommend, that can be purchased here in Europe?
And one final question, is it straightforward to do the bearing change myself? I've never attempted a bearing change before but am pretty mechanically minded.
I'll be really grateful for any help and info.

Cheers, Dave.

P.S. My dealer is DipiMoto in the Netherlands. Great mechanic but bloody expensive going by the cost of the bearings.

CBR bearings has what you need. Ask Noel about them, he has all the information. 300 Euro for bearing seems like a lot.

Is your chain too tight? Why are your bearings wearing out so quickly?

Yeah... This is what they charge standard for this work. But I thought that they had an upgrade bearing which wears out less...

Anyway, on this forum there should be enough information to find to do the work yourself. Noel, Mitch posted enough about it.

What a beast of a motorcycle!

Blimey..That seems a bit steep

The bearing ..It's only the twin row wheel side that causes grief...I would pull the hub myself..buy a bearing..that would be under Euro 50.00 talk to Noel the Knurl...
Fitting..as I work from home shop I prefer to give my bearing removal to my Engineer friend and he would pop the old one out and pop the new one in for me for less than Euro 20.00.

I could do it myself but H has all the gear and makes light work of it so why bother..

joe

ps you could buy a hub and bearings for E 300.00 ; )

The bearing is the updated version according to the shop!!
The chain isn't too tight and the pinch bolts are correctly torqued, so I've no idea why I'm getting excessive wear. The bike has never been subjected to jetwashing and has hardly seen a drop of rain

Cheers, Dave.

The bearings need inspection, clean and renew grease, but should not require replacement so soon. My 208 910R has over 20,000 miles and I have not needed to replace the bearings yet.

I use a Valvoline product CV Joint grease when I service them. Very high pressure/high temp grease.

I used to be fast....now I just dream about it.

Hmmmm... Did Pieter actually show you the worn out bearing??

Did we forget that the manual recommends replacement of original bearings at 8K or something like that ?

What's the labour charge per hour in EU at the moment, a shop can charge for up to 2 hrs to service a hub.

Does DipiMoto, replace both bearings ? They've been racing MV's for a very looooong time you know.

bearings?

what a rip off

$400 for a $34 bearing and changing it

Donsy;
the bearings are 'serviced' at 12,000 and 24,000, the hub is to be replaced at 36,000

Dave;
i've supplied 100s of these bearings and as yet no one has reported a single failure

you'll spend far more time cleaning parts than changing the bearing

as Ed said use CV joint EP grease, available everywhere
