Class of 2010: Pirelli Supercorsa SC Tires

Three out of five manufacturers can't be wrong

In view of the fact that the majority of our testbikes came equipped with Pirelli's Diablo Supercorsa SP tires-the harder, more durable version of the Supercorsa SC race tires-we thought it appropriate to stick with the Italian buns (now made in Germany) for the track portion of our test. Our friend Chris Maguire at CT Racing ( was happy to hook us up and lever a set of Diablo Supercorsa SC2s onto each.

The single-compound Supercorsas feature Pirelli's sparsely treaded cap in your choice of super-soft through medium mixtures. The patented zero-degree belt is said to balance rigidity and elasticity for the best in control and compliance, and to work in conjunction with a steep profile and slick shoulder to create a large contact patch at full lean.

Our Infineon test was our first opportunity to try the new race tires since they underwent a minor compound update in 2009. The tires' flexible carcass simplified chassis setup, and despite cool temperatures warmed up and were ready for action within one to two laps. The front tire had a neutral feel and provided excellent braking stability and feedback, while the rear's tendency to squirm under hard acceleration served to notify us of impending slides long before the wheel began to spin. At $178 front and $208-$219 rear the Supercorsas are competitively priced, and considering how little wear they showed at the end of our testing, they're an excellent value.
