Not really. It can't be seen without dismantling and you can't always feel any play / slack in them from lifting the front wheel. I've got a very slight vibration when braking hard... I suspect this is the culprit.
To be honest after having the forks serviced, replacing the wheel bearings, brake discs, brake calipers and pads along with the MC it couldn't have been anything else! Fingers crossed!
No they are Koyo and expensive. I did hit a rather large pothole and this probably broke the bearing and seal.
