I got turned onto those Dunlops by a mate that has since passed (taken by the road gods). Before these I was running the Michelin Pilot Power 2CT, a nice dual compound with a firm center and softer sides. Though, in use, I didn’t find that it cupped any slower, but I did like the sidewalls.
Comparatively, even for a 120/70, the Dunlop front has much steeper sidewall than the Michelins do. I tend to favor steep walls as, back when I raced, I used a 24mm offset to the front, so having a “nose over” feeling is much more comfortable for me.
These Dunlops are indeed good enough that you can ride them to the track, do some laps, and then ride them home - as long as you’re not pushing it past the 75th percentile and leave yourself room, they’ll be under you all day long. That said, I tend to prefer mother nature any more - not as much speed, but even more precision and infinitely more variation, though the run off sucks.
