OEM seal is £19 in the UK

Std dble lipped oil seal is only a coupl of quid from a bearing factor

However, the OEM seal is not a std seal - it has a larger ribbed lip on the inner side
This may be the cause of your issues
If your seal is leaking, as said above, always change the collar as well.

A mistake commonly made with the YZF/WRF is to install the seal too deep in the bore. When this is done, the lips of the seal may over hang the "castle" notches on the inboard end of the collar, creating a built-in leak. The seal needs to be inserted square with the bore, and positioned so that it stands proud of the end of the bore by about 1 mm or less, but no more than flush with the case.

Definitely inspect the collar. Any distinct groove worn in it will keep it from sealing.
