Unlike Michelin for instance, the SuperCorsa gets warm fast and is never a problem. I would not try scratching the pegs right out of the garage, but once the motor is warm, the tires are fine. I have used them on the road myself as well as several sets on the race track on different bikes. My SOS Skorpion weighed only 125kg ready to race and the admittedly much stronger Bimota only 135kg ready to race and the SuperCorsas are up to temp after about two laps. For actual racing we used tire earmers, becuase you can, of course, charge right off the line and, more important, tire wear is better. As far as that goes, my blue street Skorpion weighed only 155kg. Never a problem. They never let go without warning, which cannot be said for PilotPowers at all, which until they are warm are downright treacherous on anything weighing less than 200kg and with less than 100HP.
The new
Diabolo rosso may be a good alternative available in the right size. I have not tried it yet.
Not as good but more than good enuf, especially on the street, the
Bridgestone BT090 Pro which is my personal choice. It is good even cold and very good in the wet which goes hand in hand. Handling is superb. Its big drawback is wear. YOu can't have everything,a d if you think you need pegs cratching, knee down grip, you are not going to get good wear from any tire, regardless. If you have race track ambitions, however, the BT090 is not a good choice because it gets too hot too fast. It doesn't get dangerous, just starts to smear but remains controllable. Lets you drift like the big guys, if at a much lower speed. Not fast. But for really fast road riding it is more than anyone in this forum can ever need.
While availabe in the 150/60, I alway run this tire (SZR and Skorpion) in 140/70 as Bridgestones, unlike Pirellis which tend to be very narrow, tend to the wide side: The 150/60 SuperCorsa is 143mm wide on the 4" rear wheel. The 4" wheel is too narrow for a 150 tire anyway according to the manufacturers: Pirelli 4,25"; Bridgestone 4,5".
Where good wear is one requirement, wet grip another and all out knee-down grip not that important, there is only once choice on the market:
BT45, here, again in 140/70 on the rear wheel. Haven't I just written a long piece o this stuff?
I have ridden
lots of miles with this tire on the Skorpion, both in 140/70 on a 4" rim an 130/70 on a 3,5" rim and
never had any grip problems at all; handling was described by others after trying the blue bike as being like a mountain bike. Of course there were occasions where I could feel the front scuffing, occasions were the knee was way down. But it does not suddenly slip off like turning the lights off, no warning, no nothing like the Michelins or the old Pirelli MT01(
DO NOT under any cirumstances use this tire) do. FWIW, we run the BT45 on the 3 cylinder 1200cc Laverda racer and have not yet(!!) gone down due to the tire letting go.
It is shiny in the middle due to starting with the the starting machine, after a lap that is gone.
Another Brigestone available in 150/60:
B016. Again, I have not had a chance to try this one but it could definitely be worth it.
The Conti Road Attack has a good reputation but I cannot comment on it. Since it is popular in the Sumo scene, I suspect it is much like the BT090, also very popular there, in that it gets very warm very fast and is easily driftable. Thus, for street use, just right.
