Triumph Speed Triple R Rolls on Pirelli SC

2012 Triumph Speed Triple R

One of Triumph’s newest machines, the Speed Triple R, is enhanced with many performance upgrades directly from Hinckley in the UK.

The 1050cc machine arrives stock with Ohlins suspension, Brembo brakes and some unique rubber – Pirelli Diablo Supercrosa SP tires.

These tires derive directly from the SC (Special Compound) version of the same tread pattern adopted in the Superstock 1000 FIM Cup.

The 2012 Triumph Speed Triple R will arrive stock with Pirelli Diablo Supercorsa SP tires, with a 120/70 ZR17 up front, and a 190/55 ZR17 out back.

Pirelli’s Diablo Supercorsa SP uses the same profile of the SC version, providing flat areas on the shoulders, increasing the tire’s contact patch at mid lean when the rider is still braking or opening the throttle and an optimal variation of this contact area linked to the lean angle to give the most progressive response.

The advantages are high stability and cornering speed, more confidence-inspiring feedback, with a greater feeling of security on road and on racetrack and an incredible traction for opening the throttle earlier than ever. This tire is characterized by a front casing, which keeps the tire on ground even under a low load, and a rear casing designed to improve the pressure distribution on the road surface.

The tread pattern maintains the same design as “SC” or Special Compound racing tires. While the performance-oriented development of land/sea ratio distribution respects FIM Supersport regulations, most tread grooves are concentrated on mid-lean area, leaving the tire crown and shoulders slick-like to improve grip.

This design is aimed to give stability avoiding any jelly effect, to improve the ability to hold a line and to reach the maximum consistency of performance, a key contributor in reducing the total race time.

The SP compound extends the mileage vs. racing specific compounds and withstands perfectly for extended periods of time the temperature variations typical of road duty, providing also higher performances on wet ground. The stiffness and friction coefficient compound has been studied to allow all riders to find a very high cornering precision supported by anoutstanding contact feeling without affecting the well-known high stability and absorption behavior of Pirelli Supersport tires. The most important element of the Diablo Supercorsa SP compound is the unique possibility to guarantee quick warm up compared to the SC version as well as typical road performances like durability and high speed stability in a straight line.

Pirelli Tire North America designs, develops, manufactures and markets tires for passenger vehicles in both the original equipment and replacement markets as well as markets and distributes tires for motorcycles and motorsports. Located in Rome, Georgia, Pirelli’s Modular Integrated Robotized System (MIRS) employs state-of-the-art technology to manufacture automobile and light truck tires for both export and domestic markets.
