Just Rang and Organised myself a BT023 Rear Tyre for the ST1100, $227(With our Group Discount) Purchasedat Tyres for bikes in Brisbane that includes fitting and the bits and peices.
Going to get it just before rally, as i have had really good wear out of my Last Rear Tyre, I bought it on the 09/06/2011, and i have done over 12,000km out of it with alot of pillion riding, so cant complain at all :)
