The latest addition from Hinckley will use Pirelli’s Diablo Supercorsa as original equipment with a 120/70 ZR17 tyre for the front and a 190/55 ZR17 on the rear
Jerez de la Frontera, 26 January 2012 – The new Triumph Speed Triple R, recently presented to the international press during EICMA, will roll on Pirelli Diablo Supercorsa SP tyres derived directly from the SC (Special Compound) version of the same tread pattern adopted in the Superstock 1000 FIM Cup.
The front mounts a 120/70 ZR17 sized tyre while the rear takes a 190/55 ZR17 and the combination delivers pure race performance with all the added advantage of road use. Pirelli’s Diablo Supercorsa SP uses the same profile of the SC version, providing flat areas on the shoulders, increasing the tyre’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 tyre 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 tyres. 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 tyre 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 an outstanding contact feeling without affecting the well-known high stability and absorption behavior of Pirelli Supersport tyres. 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.
