We run Pirelli SuperCorsa SC-2's on our '91 ZXR250 endurance bike. They are very sticky and will last us about 10 hours and pure shagging on a tight 1km course. (only 2 left hand turns so the right sides get worn out long before the left)

We previously ran BStone 090 Pro's because we had an 18" rear and while they lasted FOREVER, the traction left a lot to be desired.

Having seen what the SC-2 offered, we kinda wished we reconfigured the rear to a 17" sooner!

I'm going to fit some SC-2's for mine in the next few weeks for the track.
