Looking for some reasonably priced discs for my extra set of wheels. I'm guessing they are the same as the F650?
I bought used F650GS discs off of ebay for an OK price (around $40). Glich_oz bought a set if those Chinese discs, I would check with him and see if they are working out. http://www.cafehusky.com/threads/oem-or-out-there.81164/#post-541127
You can purchase high quality front and rear discs from MetalGear here in Oz,they export but they have not updated their catalogue fully for Terra/Strada, the models are listed but not front disk. You want the BMW F650GS disks, or the BMW F650 which is counter bored on the mounts. We had my worn out front disk with a good disk off a Terra sitting together last week
