Sorry Fluteplayer - local bike shop said they are specials only available from Yamaha at present


Oh well, I will have to bite the bullet and pay yamaha prices then! Thanks so much for taking the trouble to enquire on my behalf.

You could try taking the measurements to a local bearing factor to see if they can help, as Yamaha sure ain't making the bearings themselves, they are sourcing them from somewhere in Japan.


I will, and see if they can be matched. If so I will post the details up here, I am sure they will be useful to people in the future.

Thanks again for trying!

If you have taken the bearing s out , then measure the inside Dia, outside Dia and the width of the bearing, note if theey have seals on the (probably will) Then good to a bearing supplier like BSL and they should be able to sort you out.

Not always true - BSL can source most bearings inc all of the common ones, but as I stated in an earlier post, some bearings are specials not available in this country through normal distributors (ie they are non standard sizes), meaning you have to buy them through Yamaha or Suzuki etc at their inflated prices.
They do this to stop you buying std bearings - so more profit for them. Bastards ranting.gif

The quest continues!

I finally gave in and bought some Yamaha rear wheel bearings, I will use the sizing and other information to try and find out whether there is a pattern replacement available.

The bearings are marked Koyo 60/28RK

They are sealed (both sides)

At room temperature, the following sizes were measured:

ID: 25.5 mm
OD: 49.5 mm
Depth: 9.5 mm


The sprocket carrier bearing is widely available and is # 6206


I will report back with any further information!

Thanks FP.

Koyo seem to do alot of the OEM bearings for Yamaha.

That Koyo part number would allow you to cut out the middle man (Yamaha) and prolly half the cost by going to any good bearing supplier....though you may not want to know that now unsure.gif They will also be able to cross reference to other bearing manufacturers.

Moved to Knowledgebase so others don't have to go throught he hassle you have. good.gif

KOYO do bearings for all the jap bike manufacturers, because they are one of the worlds best manufactures of bearings. they are top quality bearings and you won't buy better even if you spend more.

Anyone know what the part number of the rear wheel bearing is for an '02 900, eg 6206(sprocket carrier) or 6004(front wheel)
Can't seem to find it listed anywhere.

Taken from the '04 parts list, but I presume it's the same bearing:

seem to remember this discussion a while back and that it was a special, but then it was found at B&C Express

Let me find the thread

Here it is in the knowledge base

http://www.carpe-tdm...?showtopic=2657

Rear wheel bearings are 60/28 2RS - 8.48 from B&C, although should be able to get them from any bearing factor

Seems a std 60/28 bearing is 28x52x12mm, but according to Fluteplayer, he measured his wheel bearings (which were marked as 60/28 as 25.5x49.5x9.5mm, so it seems another case of bearings marked with a std number but are actually different (see below)

Suzuki are pulling the same stunt with the main bearings for my DRZ400. they are marked as 6306's
They are the same as std 6306, but 18mm thick instead of the normal 19mm. - std 6306's are about a tenner from a bearing factor or generic Koyo from the bike shop, but these specials are Suzuki supply only at 45 ea.... WTF!

90 for a pair of main bearings - robbing bastards

Thanx sparx, but I've got that that number I was after the BEA number(see GG's ppost above) but it is, as I feared a special bearing.

whats the yamaha part no's then
usually the bearing code is embedded into the yamaha part no somewhere

ie if it were a 6204 bearing, then those numbers would be somewhere in the yamaha part no.
My bike shop always look at the yamaha part number then comes up with the std bearing number this way


this is from the link in GG's post above, and if this is the case then:-
We know the front wheel bearing is a 6004 and the yamaha part# is-93306-00420-00
So if we follow that rationale then the rear wheel bearing part number being 93306-07806-00
should make the bearing a 6078.
I'll call in at my local factors tomorrow and try out this exiting new theory.

Yes - I agree it should be, but if you look in the thread I linked to in my post above, you'll see we've been there
6078 isn't a bearing
Actually bearing is a 60/28 but the std 60/28 isn't ther same as the ones fitted to the 9'er rear wheel - unless anyone confimr otherwise

Measure the bearing and buy SKF.

I'm sure you'll find a local dealer on their webpage.
