It’s tough to disclaim Pirelli’s dominance within the Malaysian superbike tyre market, extra so with the introduction of the Pirelli Diablo Supercorsa V4, in SC and SP compounds. Whereas many sportsbike riders have gotten used to utilizing SC compound tyres on the street, the distinction is now distinct sufficient that Pirelli warns in opposition to utilizing it thus.
However why the sudden division between the Supercorsa SC (Particular Compound) and SP (Sport Manufacturing) tyres? First off, the SC, or Supercorsa SC V4 in its newest iteration, is a observe use solely tyre, whereas the SP is a dual-compound tyre for street use (although you possibly can take it out on the observe.)
To that finish, Pirelli Asia invited paultan.org out to Sepang Worldwide Circuit to check the brand new Supercorsas, mounted on a pair of Honda CBR600RRs. The Supercorsas had been mounted on two bikes arrange virtually identically, to permit for straightforward back-to-back comparisons.
We took the SP outfitted observe bike out first, to see what variations there have been between this and the (extraordinarily giant variety of) earlier technology Supercorsa SPs we’d ridden over time. First off, we seen heat up was fast, with no tyre heaters put in.
For a road oriented sports activities tyre, the Supercorsa SP is, as talked about earlier, constructed from two compounds. The centre of the tyre has a rubber compound designed for put on resistance and constant grip, whereas the perimeters are created from a softer rubber combine giving distinctive grip when the motorbike is leaned over.
By way of suggestions, it was famous the Supercorsa V4 SP gave higher response to the rider, particularly from the entrance tyre. Pulling in after 4 laps, a request was made to alter tyre pressures entrance and rear, going up two p.s.i. from the 30 entrance/28 rear we set out with.
Heading out, there was a marked enchancment in flip in and response, permitting the CBR600RR to stick with and sometimes overtake the 1000 cc tremendous bikes within the corners (though all bets had been off within the straights.) Efficiency stayed constant all through the session and although we’d have favored to essentially take the SPs to the tip simply to see what it will really feel like when efficiency dropped off, time didn’t allow.
Altering over to the Supercorsa V4 SC, it was instantly famous the sidewall flex was rather less in comparison with the Supercorsa V3 SC. We guess it was inevitable, with Pirelli’s participation within the World Superbike Championship, that its manufacturing “race” tyre would develop into much more race centered.
Right here’s the factor, for those who mount the Supercorsa V4 SC in your street bike, then experience it on the street, any shortcomings in your suspension setup are going to develop into readily obvious. That is an unforgiving tyre meant for race use, and for those who do take this up Goh Tong or Bukit Tinggi, you do it at your personal danger.
Out on the observe, the V4 SC exhibits its pedigree, it being a really centered, single compound, race tyre. The tyre may be very fast on the flip into corners, and doing the flip-flop when altering route in turns 4, 5 and 6 confirmed no hesitation and instability.
Near the sting, the SC tyre consists, and within the phrases of C Y Khoo, who races for Mobilub Suzuki Racing Staff on a Suzuki GSX-R1000, that is adequate for, “a number of seconds gained, particularly within the again half (South Observe) of Sepang.” Once more, we weren’t capable of decide tyre life as we solely had a few periods out on the observe, one thing which can name for extra observe time and tyres.
So, on the finish of the day’s testing, a few factors had been obvious. The Supercorsa SP, whereas efficiency tyre and can be utilized on the observe, is finest suited to sporty street driving, this being one thing your pockets will thanks for.
The Supercorsa SC is meant just for observe use, and at the side of tyre heaters. On the observe, the SCs are chic and rewards the rider with suspension setup and easy driving model.
