Funny enough, my mate has just bought some Supercorsas for his 748 (but then he is a big Pirelli fan). He picked em cause he was told the very same thing.. and because he got a good deal at the time.
Of course, his duke is a lot lighter than my zx (which is made from girders), and so I hope they would suit mine too.
When I went to Wheelhouse tyres, they recommended the Rossi's, and the new dunlops (if I had an extra 50 quid). He also said the 2CTs were a little long in the tooth, and (again) said the new Dunlop Sports were the best (and his own favourite) choice..
Like you say, it seems to be a very personal thing..!
Mind you, he also said that most modern tyres would do the job..
So I've decided.. next week, I'm gonna buy some tyres, and they may be pirelli..!
(possibly)
