Whining sounds from front end once over 25mph

[Arfa]

Just back from garage. Took wheel off and had a good nose round. Reckoned there was no obvious issues with bearings, just gave everything a bit of a clean and greased up bearings and speedo as it was looking quite dry. No noise on ride home, so hopefully sorted! Yes, speedo thing is the speedo rotor, plastic ring with couple lugs on it. Garage said they'd seen a few Fazers with a similar issue. Either way, they only charged me a tenner, so canna moan really.
