Well, I have just fitted a set of these to the bike. I'm going to post regular updates in this thread as to my observations over time. Minor snag though, the battery isn't charging in my bike. Seems to be a regulator/rectifier fault. Easy fix once idenfitied as the cause, but waiting on parts. I'll be about riding again as soon as possible. In the short ride I had them on through traffic before the battery died and the bike stopped, I observed them to offer a slightly more plush commuting ride than my old tyres (OEM Supercorsa Pro), and turn-in into corners appears to be very progressive. You keep rolling the bike over further on the lean and it's not like the tyres want to be leaning at a different angle than the one you're on like some of the racier profiles can feel like. The Rosso's are happy with where-ever you put them. Unfortunately, that's about it for observations so far. I've been reading up extensively on the Rosso's, so perhaps it might be better to explain my expectations from these tyres, and why I opted to try them out. Pirelli are marketing the Rosso's as a replacement for the straight up sport-touring Diablos. Reading through Pirelli's technical material though, the Rosso's are meant to be offering 10% more traction which would put them in about the same ballpark as the old Diabo Corsa's (before the Corsa's got recently replaced by the Diablo Corsa III's). I've ridden on the old Diablo Corsa's at the track, and on the road, on the old R1. Yes, while the ~145rwhp of the R1 could overwhelm the traction of the rear tyre, I was scraping the pegs while winding the throttle on strongly when that happened. On a super-sport capacity bike I'm not perceiving that this is going to be an issue, and certainly not on the road. I have no plans to head back to the track in the near future anyway, so track performance is not a concern for me. One thing that I've observed with the OEM Supercorsa Pro's is that I don't seem to be wearing them out fast enough before they're going off due to heat cycles. Started having a few slides here and there, and so I'm hoping that the newer compound on these Rosso's are able to hold up for longer. A few of the videos I've found online have shown people at the track getting the tyres right to the edge, balling up, and not breaking traction even then. The advantage with more racier compound tyres is that when at the track you can keep leaning even further than the edge and still have grip even though you're operating on a diminishing contact patch portion. For me, on the road, I've observed that I am taking my road tyres to the edge but with some feathering on the last 1mm indicating that I'm not absolutely on the edge. That's at about a 50 degree lean angle too, so given that, I'm not expecting any traction issues even given my fairly enthusiastic road riding style. If guys can take the tyres right to the edge on the track (but not beyond) and not experience any loss in traction, then that's all that I realistically need for the road. More updates after I get the bike back. I'm looking forwards to seeing if in practise these tyres hold up to my expectations above.
