Excellent side grip
under acceleration is
a Pirelli trademark.
The Rosso Corsa II is
no different.
In order to deliver a tire capable of handling both
everyday riding and racetrack demands, Pirelli
employed a multi-compound design for the front
and rear hoops. For example, the Diablo Rosso
Corsa uses a bi-compound structure up front,
which is integrated in three different zones. The
center compound is constructed of a 100-percent
silica construction in order to provide grip in both
wet and dry conditions, as well as straight-line sta-
bility. On each edge of the front hoop, a 100-per-
cent carbon black compound is used to promote
as much grip as possible, while providing enough
feedback to the rider to boost confidence during
spirited road or racetrack riding.
Pirelli engineers used a similar construction
on the rear tire, except using three compounds
over five different zones. The center portion is a
compound constructed with a high-silica content
to achieve high mileage, high-speed stability and
even wear. Like the center compound on the front
tire, the intermediate sections of the rear shoe
feature a 100-percent silica construction, and the
shoulder sections are built of a 100-percent carbon
black compound with the same resins used in the
Diablo Supercorsa racing tires used in WorldSBK.
Unlocking true sport performance from the Dia-
blo Rosso Corsa II meant pulling technologies from
its racing efforts, including dual radius technology.
The center of the updated Rosso Corsa II features
a sharp radius design, which is meant to increase
the speed of side-to-side transitions while remain-
ing stable. Shaping of the profile on the tire's
edges transitions to a wider radius at 35 degrees
of lean, helping create a larger contact patch
