Are you in the UK or AU? Shipping is not that good right now to be trusting EMS to move even a small part from USA to UK or even AU. I have some parts that have been stuck at Ohare airport customs 2 weeks now that came from the UK. No release date posted on USPS since it is royal mail.
There is a UK S1000RR forum and maybe you can get one there and shipping is closer.
The mirrors are the same design 10-19 K46. The 15 and newer do seem a little better in how they swing to folded position and back to ready to use.
