Pirelli will continue to supply tyres to the World Superbike Championship until the end of the 2015 season after organisers Infront agreed on a three-year extension.

Infront had invited alternative companies to apply for the tender, which would be applicable for the 2013, 2014 and 2015 seasons, but an announcement confirms it will remain associated with the Italian company for at least another three years.

Pirelli, which has had an exclusive deal to supply the series since the controversial decision to adopt a control tyre from 2004, will continue to supply the World Superbike Championship, together with the Supersport, Superstock 1000 and Superstock 600 categories.

"We are delighted to be able to renew the contract with Pirelli until the completion of the 2015 season," Infront CEO Paolo Flammini said. "Eight years of working together have provided results that go way beyond our highest expectations. Once again we can count on a tyre supplier, whose commitment to the product, service and development is second to none.

"The presence of 7 manufacturers in World Superbike and full grids in all four classes requires a supplier who can guarantee total excellence from all points of view, and Pirelli have fully respected those guarantees, providing stability to the championships and contributing enormously to their success. We would like to thank them for their commitment and support and look forward once again to a long-term future together."
