There have been a few instances of bearing failure on the rear hub of the F4, these are supposedly due to overtightening the pinch bolts on the swinging arm.
The bearings are not available separately from MV Agusta and in fact the complete hub assembly has to be purchased at a cost of over £500!
One of our members has had a similar failure and he has found a supplier who can offer the replacement parts.
Please find the bearing numbers and the supplier details below.
Thanks Waggy!
