Pirelli Diablo Supercorsa SP Tire Comparison Review

Monday, November 1, 2010


The Pirelli Diablo Supercorsa SP looks virtually identical to the DOT-legal road racing tire.

The fourth A Group tire in our tire comparison is the Pirelli Diablo Supercorsa SP. This is the Italian tire conglomerates top-tier street tire. It is modeled after its World Supersport-spec Diablo Supercorsa road racing tire and comes as standard fitment on a few new sportbike models including the Ducati 1198 Superbike and Triumph Daytona 675.

Next to the Michelin Power Ones, the Supercorsa SPs are the most expensive tire in the test ($377.98 at Motorcycle-Superstore.com). However for your money you get an awful lot of performance. The front tire weighed in at 9 lb 2.1 oz which gave it claim as being the lightest hoop in its class and second-lightest out of all 10 models tested. The rear rubber weighed 13 lb 8.8 oz which placed it toward the back of the class but still ahead of the tires in the B and C Groups.
 
At both the Streets and the big track, the Pirellis achieved the fastest outright lap time. At the more technical Streets course, which subjects the tires to heavy loads during braking and acceleration out of its slow-to-medium speed corners, we recorded a lap time of 1’23.54 which was just 0.34 seconds in front of the Dunlop Q2. At the ultra high-speed big track where stability and feel are paramount the SPs decimated the competition with a lap time of 1’31.45. Part of the reason we were able to lap so quickly is the tremendous amount of feedback delivered through the controls.

The carcass felt much more rigid-feeling than the Avon or Michelin. It actually felt quite similar to the Bridgestone, however it was more communicative. When loaded aggressively with the throttle or front brake, it felt like the tires would dig into the pavement, like a paddle in the sand, instead of deform atop. This helped facilitate tremendous acceleration drive off corners. Though on the street, the Pirellis don’t soak up pavement irregularities quite as well as the competition. Again, the difference is so marginal that we couldn’t classify it as “bad” just different.

Interestingly enough the SPs are the only tire in the A Group to employ a uniform compound throughout the structure. While this doesn’t seem like it would work as good as the multi-compound set-ups on paper, in reality it does. Outright grip was superior to the Avons and Michelins and on par with the Dunlops and Bridgestones. The level of road adhesion is so remarkable and the difference so tiny that it’s difficult to determine which tire offers up more grip, so we’ll let the lap times decide that. Also noteworthy is that the grip levels stay consistent and performance does not degrade as the tire heats.

Lap times don’t lie: We went the fastest on the Supercorsa SPs. So they’re the winner, right? Well, if money was no object then these shoes would be the winner. Besides that one small concern, we literally can’t think of another fault. They heat up immediately, have loads of grip, feel and stability which make them an incredible street or trackday tire.

RIDER NOTES:

“Outstanding!!! This could be the perfect road tire. They felt similar to the Bridgestones in terms of their flex characteristics. The structure of the tire had nearly a perfect blend of stiffness versus softness. Feel, stability and grip were on par with the Dunlops and they heat up immediately. Steering was good too. It’s truly insane how much grip these tires have. This is the kind of grip racing tires had just a few years ago—incredible.”
