I'm on my second set of Avon Spirit ST's.
The bike had some sort of Battlaxe's fitted when I bought it and I thought I'd made a mistake buying my first ADV / touring bike. I tried all sorts of fixes and scared myself silly for a couple of months before I realised the tyres had asymmetric wear, so in a blast of patriotism I went with the Avon's (from a local dealer and paid through the nose for them).
A touch over 12,000 solo touring miles later I have a second set (from a different dealer and at a much better price).
