Aliexpress has some. Not sure if they are genuine or the one you want. But the price is right. ;) https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20211120171031&SearchText=Mivv
Try this https://em-moto.com/en/. The one I have cost $623 delivered. Can't remember the guys name but he seemed like a nice enough guy.
Huzo I have a Mivv on my Griso. There are a couple of dealers on the east coast but for the life of me I can't remember who. Been asleep since then. Bought mine from Italy but will have to go searching for info.
Is it the GP silencer like this one Huzzo? They are available in the UK for a little over £250 plus shipping. The biggest problem is shipping it to Oz will be very expensive. I have shipped domestic lighting there and have some idea of the cost. Probably £150+.
OK, I've done a bit of digging and found a pdf doc for the GP silencer. It seems that it is a 'Universal fit' but you also need additional accessory parts to mount it. The silencer is sided left or right, so be careful which sku you use. This is an image of a page from the pdf that contains the information you need.
