A quick ride report.
I've had the RA3's on the V7 Racer for two weeks now, and I've put a little over 700 miles on them so far.
They're remarkably better than the Pirelli Sports Demons that I had on the bike previously.
There were occasions when the Sports Demons had a bit of a squishy feeling to them; a feeling as if one didn't really know what the tire was going to do because it felt like it was distending between the road and the bike. It left a lingering sense of reduced confidence in what one could expect.
Completely the opposite with the RA3s. They feel so much more attached and really provide a good idea of what your tires are doing, where they're going, and how much more they have to give. The spongy feeling that the Sports Demons sometimes had is completely gone.
Near the end of last Sunday's ride I came a bit hot into a reverse-banked curve of decreasing radius that I didn't quite see through because of the setting sun. At that point I just needed more lean, and the RA3s performed admirably. I had the feedback that I needed to lean in and roll on the throttle to make a clean exit - and the confidence to know that the tires would stick through it. It was nice. In a situation like this the feedback from the Sports Demons would not have been so positive. They would have been much more nebulous.
So far, definite thumbs up.
