A new five-year contract has been signed between Dorna and MotoGP teams' association IRTA, running from 2012 to 2016.
The relationship between the two organisations commenced in 1992, when Dorna acquired the commercial rights for MotoGP from the FIM.
IRTA will continue to represent the interests of its members, which includes all teams and major service companies, via its representation in the Grand Prix commission and the day-to-day relationship with Dorna.
“Dorna has been a fantastic partner for IRTA for the last 20 years," said IRTA President and Tech 3 team owner Herve Poncharal. "They have constantly sought to improve the appeal of our sport via outstanding television coverage throughout the world.
"They have also taken us to new circuits in different continents and we now have a truly global audience to offer to our sponsors.
"Most importantly, Dorna has supported us and the riders by putting safety before any other matter, to the extent that considerations of the safety of the competitors is never compromised by commercial issues.
“I believe that IRTA has made its contribution to this development by delivering to Dorna the very best teams and riders to participate in the premier World Championship.
"In turn, our teams have risen to the occasion by improving their professionalism and presentation so that today the MotoGP paddock sets standards for every other motorsport. It is an environment which we can be proud to invite our sponsors to visit.
“I am particularly pleased that the signing of this renewal coincides with the 25th anniversary of the formation of IRTA which took place at Assen in June 1986.”
Carmelo Ezpeleta, CEO of Dorna added: “We're pleased to renew our collaboration with IRTA for five years from 2012 as we'll be entering a new era of the MotoGP World Championship.
"We're now building the future of the sport alongside the Teams' Association and we are committed to ensuring a successful switch together to a new formula next year for the MotoGP class and also to emulate the success of the Moto2 class with the introduction of Moto3 as a replacement of the 125 series.
“With the support of IRTA we'll also be looking at expanding the horizons of the sport so our close relationship will be instrumental in tackling new challenges in the five next years. We've been doing a great job together over the past 20 years and we're looking forward to continuing a strong relationship.”
The present MSMA (manufacturers' association) MotoGP contract expires at the end of 2011.
The MotoGP class will start a new 1000cc era in 2012, when Moto3 will also replace the 125cc World Championship.
