The D212's Racers are excellent. I stopped thinking about the tyres...started riding again. The KR106/108's just take that and turn the confidence up to 11. I was not using them to their full potential as I've still not cranked the bike over to 55+ degrees where they really shine (due to the profile). I will say this though, the KR's are so tall that on the Alpha seat (850mm) it's a real job to reach the floor with both feet (I'm ~5'11). It was noticeably taller than on the D212's.
Compared to road tyres, I'm not really sure, because I use warmers I treat them differently. From turn one you can just bang it in the corner and it sticks like the proverbial to a blanket. Breakaway is progressive under acceleration. Braking was stable and planted. Tip in is measured allowing for line adjustment with a little pressure on either bar.
The Diamond warmers with Digital Controller are so good for the money, both the fella's with me have now switched to them. Having warmers just means you can get on it straight away, assuming the tarmac is over 16degrees which it is on most Euro trips. No wasted laps trying to get them into the zone. Someone tried to scrub a cold KR108...he went from turn 1 to hospital with a dislocated shoulder, having high-sided his 1199 Panigale. Warmers are essential IMO.
Though I loved the tyres, For my next trip I have 2 sets of V02 Mediums to test. FWR were selling pairs for ?255 last week so I grabbed a couple of sets quickly as that's a saving of ~?100 over D212's and closer to ?200 on KR's. The V02's have a smaller rolling radius so the seat height shouldn't be as much of an issue. And by all reports they are equally confidence inspiring and durable.
I'm probably never going to try Pirelli's as they don't last long enough for the cost.
My pal is ok - two busted ribs and he had a bang to the head - not much you can do for the ribs. He's just dealing with it - not for the first time. He and the fastest guy there, whom he was chasing at the time, came round the 2nd to last left, heading up to the last left and got blinded by the sun - in 2 mins something up there changed which meant they were more dazzled than the previous lap. They were both on low 1:5x laps...same tyres as I was doing 2:10's lol.
