Great to read all of the replies...
The Dunlop Sportmax Qualifiers that mine came with, I'm running at 33/38 psi, which works pretty well.
May try a Qualifier II on the rear when this one wears. A bit cheaper than some of the other options but still a great tyre - great-great-great grandchild of the D207RR
I have a mate who has Angel ST's on his BMW S1000XR and rates them very highly - may give them a try in due course, but fancy trying some Bridgestones too - soooo much choice!
