Hey Happsy,
Thanks for your ideas on the problem but it was sorted out sometime ago.
Problem: rattling floating disc... solution: replace the worn bobbins.
Result :.....No more rattles!

Happy riding for 2018!
Wildhenry.

It could be cavitation of the oil in the forks, if it is just being heard at high loads there may be a shortage of oil in the forks. If it is cavitation then it could also be bad quality valve discs in the fork pistons. 
I am a chassis engineer for a major OEM car maker and have had this issue with brand new vehicles, turned out the sub supplier to suspension supplier had let their quality control slip.

I do appreciate it's difficult to diagnose a problem without looking at the bike and obviously some will get it wrong, so once again my apologies and thank you for all your help.

It is always very difficult to diagnose problems at a distance when the only information is the written word.
All the various responses given were done with the best intentions and invariably some will not be the right answer. But please don't knock those who tried to help.

I knew what was causing the problem but decided not to tell you in case I was wrong.

Hey back off dude...there is no need to get aggressive with your 'Dick talk'
Apologies if you have been mortally wounded by my comments ...I reckon it says more about you than it does about me!
Forums are really useful and I really do appreciate the help but sometimes some people don't know what the hell they are talkin' about!
Best wishes and a safe ride!

Well, is it really a problem?
As I said in earlier posts, the front disc on my R100R BMW rattles, and probably always will. Annoying, but I can live with it......but I don’t think it means there is a safety issue? Yet.

Like you, it is frustrating to read posts from peope who know all the answers but unfortunately their answers are wrong......just a forum thing I guess,

Hi all,
It's not a Guzzi quality control issue ....it's Brembo!
Ducati, BMW, Moto Guzzi and all other manufacturers that use Brembo all have the 'rattle disc' problem.
According to my local mechanic this is a very common problem with Brembo brake discs.
How come it's taken me all this time to locate what it was?  
All the incorrect information/ideas on this forum didn't help! (ie: worn head race bearings ect ect)
Anyway I'm pleased to say that all is now well and I hope this post will quickly solve the problem for others who might have it.
Cheers,
Wildhenry.

Hopefully this will help others with this problem. Does make you wonder about the Guzzi quality control though.
