I've been reading the tyre thread with interest, and note some misleading info on the Pirelli tyre range...
To the best of my knowledge (as a Pirelli stockist)
the Rosso (not Rossi) does NOT replace the Diablo. The Rosso and Diablo are BOTH available side by side in the Pirelli range (at least for now).
and the Angel ST does NOT replace the Strada. Once again BOTH of these tyres are available side by side in the 2010 range.
I can understand why it would look like the new names would replace the old faithfulls, and I can certainly see that happening in the future, but for now, they are all still available.
Also, the new "Rosso Corsa" should not be confused with either the Rosso, or the Corsa III - all 3 names are in fact seperate tread designs and compounds
for further info;
and while we're on the subject, I got 10500km out of a set of Rosso's on my 06 Sprint ST, including a track day at Taupo. they performed excellently throughout, although the front did chop out a bit on the r/h side toward the end and made the turn in a bit steppy.
I have now put on a matched pair of Conti Sport Attacks, and have done 3000km since Christmas including 2 track days at the new Hampton Downs circuit, and I LOVE them. they hang on really well, and they are wearing superbly.
I might try the Angel ST's next. they are a lot harder than the 2 previous set's but I watched a novice track rider getting his knee down on a set of these on an 09 GSXR750 at Hampton Downs, so clearly grip at max lean is not an issue.
