WSB organisers, FGSport have confirmed that Pirelli will remain the sole tyre supplier for Superbike, Supersport, Superstock 1000 and Superstock 600 classes until 2012.
Pirelli became the single tyre supplier in 2004 in which time the championship has grown with the success put largely down to the initially controversial move to a single make tyre.
Pirelli’s WSB success led to them becoming the single tyre supplier in the Canadian Superbike Championship, MotoST Championship in America and the British Superbike Championship this season.
FGSport boss Paolo Flammini said:
“The first 5 years of working with Pirelli have provided results that go beyond all of our highest expectations, from the point of view of the quality of the product, the service and the profound commitment by Pirelli to development.
"In a positive but challenging scenario from a technical point of view, and in view of the increased level of participation that in 2010 will in all probability see at least 8 manufacturers present and at least 32 permanent bikes on the World Superbike grid, we are comforted by the fact that we can count on a tyre supplier who has demonstrated that it can guarantee total excellence from every point of view.
"We are also delighted to be able to confirm a further element of stability for the championship, which alongside a package of technical regulations that is as valid today as in the medium term, now also has a definite horizon until 2012 from the point of view of tyre supply.”
