Rear Sprocket Bearing

[froudy]

The last time I changed mine I found a seller on ebay doing a pack of two for about £23 delivered, which was a good price. I keep one spare now just in case.
KOYO two rubber sealed bearings. 32x65x17

You'll probably find them cheaper than Simply Bearings if you shop around.

Froudy, i think same as me. wheel brgs local, cheap as. carrier is odd size, two spare in shed. maybe sourced uk, not sure. still very cheap. koyo, nsk, timken, skf, all good brands.

Thanks guys, got me thinking now.  Bike just clocked over 38000 kms on the weekend and I've got no idea if the last owner ever changed them.  From the history I've got with the bike I'm the 3rd owner.    I will have to take a look at both the wheel and sprocket carrier bearings at the next opportunity. No noise from any of them yet, but better safe than sorry.  Will probably change front and rear wheel bearings when I chuck a new set of tyres on.

Thanks for the good post

I wouldn't worry about the wheel bearings, mine are all original at 115k miles. However I know others on here (Vlad maybe?) have a different opinion of them.

My k2 bearings collapsed at 32000 mile just after I'd sold it took out the wheel swingarm and rear of the motor .
I wouldn't trust them beyond 20000 your just very lucky hooli

The bearings are inexpensive and easy to replace (unless done by "professionals"). No need to save a few quid here and pay heavy later.
