The AV 45 and 46 tires worked well on both my ST1100 and current 1300. The front Azaro has a tread pattern that makes it feel as though it's subtly wobbling from side to side at walking speeds sometimes, but I didn't find this to be a problem and it disappears underway. I got about 11K from the rear on my 1300 and routinely got 14K+ on my 1100. The fronts returned 19K on my 11 about 16K on my 13 with the factory recommended 42PSI F&R (40F 42R on the 1100). They handle and stick really well, no problem using all of the ST's available clearance.
One experience I've had will all Avon tires (storms and azaros) is a preponderance of punctures. Of probably 6-7 rear Avons I've used on both of my STs, I was only able to go the entire tread life on one of them without a puncture. Two of them suffered two punctures. In each case I plugged them and used them up, handling and tread life didn't appear to be affected negatively. I've never had a puncture in any other brand of tire. Dumb luck? Maybe.
The only concern I would have is the age of the tires.
