It's been a while since I've been on aus.motorcycles, good to see there's still a wealth of info out there. Assuming I get the old disk off (thanks for all the responses), I'm still a bit suss on the new one. I had to order it in but stupidly left the shop without checking it out first. The rear disks I've had previously on the FJ1200 were all the solid type, whereas the new one I've got is the type with all the holes in it. I've only ever seen this type on as front disks. It looks like it will fit ok, but just wondering if this type of disk would normally go on a rear or has the wrong disk been ordered.
