Pirelli has revealed that during the 2009 World Superbike season, its sixth year as single tyre supplier, the measured race time decreased by an average of 20 seconds over the previous year.

Reflecting on its approach during the single tyre era, Pirelli claims its first two years were spent 'refining the service element to guarantee adequate support for all riders in the Superbike paddock'.

Pirelli then 'opened a true search for performance, improving lap times and cornerspeed for elevated excitement and the shattering of circuit records'.

The latest developments have been aimed at 'the stabilisation of performance, meaning reduced lap times all the way to the chequered flag.'

As an example of its success in this area, Pirelli points out that, this year, several records were set on the ultimate or penultimate lap of a race 'such as Jonathan Rea's 20th lap in race 2 at N?rburgring or Noriyuki Haga's 21st lap in race 1 at Magny-Cours.'

WSBK was the first major championship to move to a single-tyre supplier in 2004. Although much-criticised at the time, championships such as F1, MotoGP and BSB have since followed suit.
