Mine doesnt sound like a ball bearing dropping into a bucket.I actually thought it was my keys rattling at first.I grabbed the keys to dampen them,but the rattling continued.

I haven't noticed this on mine either, although it sounds you have a different model to everyone else Bob, must be the V7 GT turbo?

The discs need to float on the bobbins. No movement can result in a binding brake or warped rotor, seem to remember that was why I had to fit new rotors to my Norge.
Maybe the best solution is earplugs or removing any dB killers......

The bobbins provide a flexible link between the central disc carrier and the brake disc itself to allow for expansion when hot. But it shouldn't be loose.
 
If there is movement which you can feel between the disc and carrier then it's a potential MOT fail or at the very least an advisory warning. Why not go to your local friendly MOT man and ask his opinion?

The 34000 mile disc on my BMW has movement parallel with the wheel axle, which I would expect but no circumfrential play. So while it rattles I. think it is all OK.

BUT

The 4000 mile disc on my V7 disc does have circumfrential movement of about 1mm....wonder if it has been like that from new?
Can others check their bikes and feedback
No rattles or anything else seems wrong with it
Cheers

Hi Guys,
Thanks for all your input on my 'annoying rattle' problem.
On reflection I think my original description of "a ball bearing dropped into a plastic box" was not very accurate......sorry!
The noise is definitely more of a metallic rattle/clunk sound!  
As I mentioned there is a bit of play when the front is lifted, brake applied and the wheel moved back and forth rotationaly.
Over ordinary bumps in the road surface there is no noise at all, just the more deep ones.
I'm 99% sure it's a loose floating disc.....thing is how do I solve it?

Unless I'm much mistaken what you described is the standard test for loose steering head bearings.
V7 Classic Black and gold is the best colour

I've checked the bearings and they are OK.....but the front disc actually moves a hell of a lot though!
! was thinking that  if I 'punch' the centre of the bobbins to stretch them out in effect would that fix the play that's causing the noisy rattle?

My bike is a 2012 and has only done 11,000 miles surely the front disc can't be knackered already?

Hi Wildhenry,
Movement of the front wheel with the disc locked by the brake is normal. My V7 II makes a "clunk" if I rock it back and forth with the front brake applied, it's the disc taking up the slack in the bobbins.
It's always had this amount of slack from new. I can feel the front wheel move between the clunks.

I also get a random "clunk" from the front end on bumps in the road, but very random and very occasional. I've just ridden the most potholed back lanes you can imagine and not a peep from it... Yet tomorrow I'll ride to work and out the blue there'll be this loud "clunk".

Just put it down to character, I'm prety sure there's nothing wrong.

PS. Another source of this type of noise (on my bike at least) is electrical connectors under the seat area, hit a large bump and they'll tap the frame.  That's just more character, one day I'll get around to adding a few more tie wraps.

Ciao, Pete.

I was reading a similar story on Guzzitech yesterday regarding the new V7 so it seems the quality control is lacking a little.

A bit of movement in that situation would not be enough to cause a noise in operation. That amount of movement is correct.
