Welcome to the Forum, Peter.
Excellent choice of FarWeapon! Plenty of expertise in this Forum, and quite a few of us doing FarRides and IBAs, as you are well aware. The ST rivals the Feejer in this class, but it's more touring oriented, less sporting, hence I believe, better suited. True it hasn't been developed the way the Yamaha has, but it is a solid bike to modify to your needs. I've done it to 3 ST13s now. There are a few excellent suppliers of the specialty bits you'll need.
There are a few of our number in Sydney- check out the Member Map and RTE announcements.
