Have always preffered Pirellis on my 900ss/900sl. I took off a half worn set of 207s and put Diablos on about a week after I got the SL. Best money spent so far.
If everyone wants a control tyre then I'll run with whatever the choice is without grumbling. I'd rather have something that was pretty good in dry & wet than something great in the dry and lethal in the wet.....
