Avon azuro st's fitted to the busa and on the last rear got 6k,now that ain't bad at all,on top of that they are far more user friendly than the oe Bridestone BT56j's made specific for the busa 
That is excellent Dude, I've never managed to get above 4k out of any of my tyres, and when I had Rensports on my Gixer I only got around 3k.
