Today I was cleaning the V7 850 and noticed the front disc outer was moving. Is this because its called a floating disc and that I am worrying to much?
Never noticed this before on any of my previous motorcycles.
Many thanks.

Hi. If you mean that the disk itself moves a little bit side-to-side, thatās absolutely normal. Yes, thatās because itās a floating disk. Itās because the disk isnāt clamped up tight on the mounting bobbins. The disk on my 2022 V7 Special also moves up and down a bit (about 1.5mm movement), which isnāt what itās supposed to do. Iāve heard that some people had disks replaced under warranty for that āissueā but I donāt think itās too serious so Iām just keeping an eye on it for now.
Regards
Tony
That what I thought but better to be save than sorry.
Many thanks.

My new V7 Stone SE is the same having checked. Thanks for posting.
I have spoken to my local MG dealer and all is well.
Learning all the time 
Your bobbins have gone loose, this is a common problem with this model. The OEM front disc is cheap Chinese tat, apparently! 
Mine went bad before the first 900 m service! I replaced it with the equiv. version from EBC, and it didnāt escape my notice, why are EBC even needing to stock this alternative item! Itās their own version, e.g. the centre is machined from soild billet, or somesuch. In any event, bobbins should not be loose. 
We certainly are learning all the time. Nothing like it on my Triumphs
Cheap Chinese tat. I though this was an Italian hand built flying machine 
LOL
Nothing like this on my Bonnevilles but thanks anyway.
In order for the disk to āFloatā presumably the ābobbins need to be looseā /designed in such a way for the disk to float. Why do they need to float anyway and what are consequences if the disks didnāt float. If they are designed to float, why replace them?
This seems to explain it!

Many thanks.
Very good, yes itās about heat expansion. Also, the disc does not centralise itself to the pads, if the caliper has pistons on both sides, the pads should adjust themselves to the disc, same as for solid discs on the older models.
Thereās a distinction though, single-sided calipers, having one piston on one side only, must be used with a soild disc, not a āfloatingā one, because the whole caliper is being shoved sideways (on its sliding pins) by the single piston pressing against one side of the disc. I believe this is the case with the rear brake on this bike isnāt it?
Iām sure fashion has a lot to do with it too, as racing style bits always looked cool.
All instructional videos should be this good! Thanks for putting it up.
