Loose front discs

[SteveS RT]

I've had my 2014 RT for a week now and dropped my front wheel off to get a new tire.

While moving it around I hear a "chink" sound and find that both disks have some play in them.

I can move each one, just a little,  maybe 0.010" or less.

 

is that normal?

Other bikes i've had have been very solidly mounted.

That is pretty normal as your brake rotors are semi-floating so aren't solidly mounted to the wheel.

Thanks, like i said i'm a bit new here.  it is certainly a different animal than my last 2 FJRs.

DR, if there were excessive play in the rotors, could that be the cause of the high-speed vibration?

I was wondering if it could be related.... but i'll have  a new tires on the bike by this weekend.

Possible, but the rotors should not be  loose enough to run out far enough to cause issues (at least at speeds that a BMW can move at). Most if not all  of the looseness or play should only be in the rotation direction.

The disc movement should only be lateral, not rotational. So they should not induce vibration.
