125-200cc wheel bearings wre / sms 125

Hello all. I've spent half an hour looking for some front wheel bearings for my bike, all seem to be £10 to £18 which seems a lot, does anyone know what size they will be and if they can be bought cheaper instead of in a kit specifically for the bike? I found these

but they don't say for the wre/ sms 2005, only the wr 02 to 13 so I don't know if they'll fit or not as the wr has some differences. Wheel's I'm assuming are the same but don't want to order and get the wrong ones!
