The Moto2 class, which was initially brought in to replace the 250cc two-stroke class in 2010, has since its inauguration been running a single-spec Honda CBR 600cc engine, with the aim of the championship to drive chassis development and uncover rider talent.
It has been a hit with riders and fans from the start, and is providing ever-greater spectacles out on track as the series progresses.
New from 2013 is that ExternPro, part of the Parque Tecnólogico de MotorLand Aragón, will be the company preparing the engines for competition, ensuring their reliability, as well as carrying out regular maintenance. The three-year agreement sees the ExternPro-prepared Honda engines go head-to-head for the first time at this weekend's Commercial Bank Grand Prix of Qatar.
Dorna Sports CEO Carmelo Ezpeleta commented: "Moto2 has been a success from the start, and just continues to get better! Honda has been our sole engine supplier since the inaugural race in 2010 and I am extremely pleased that we will continue to use its machinery for the next three years.
"The Honda engine has not only proved an exciting addition to the paddock, but has also been a technically very reliable asset, which is extremely important in motorsports. I would also like to welcome ExternPro on board, who have so far done a very good job during pre-season testing, and will no doubt continue to do so throughout the next three season".
Shuhei Nakamoto, HRC Executive Vice-President added: "Honda is happy to continue to supply the CBR600 engines for the Moto2 category, as this class has been proven to be a good way to keep costs down and allow riders to prepare for MotoGP, as Stefan Bradl and Marc Marquez are currently demonstrating. We also welcome ExternPro as new partner to prepare the engine ready for racing".
Meanwhile, Yamaha Motor has entered an agreement with MotoGP rights holder Dorna Sports SL to supply YZR-M1 engines on an annual lease basis to teams participating in the MotoGP Championship.
Yamaha Motor Co. Ltd announced on Saturday at Doha, ahead of the Commercial Bank Grand Prix of Qatar qualifying sessions, they would offer an engine lease supply for teams competing in the MotoGP World Championship, in an effort to increase the options of competitive engines in the premier class.
The agreement comes as a result of Yamaha's work with Dorna and the sport's governing body, the FIM, to further promote the MotoGP World Championship; the Japanese manufacturer engine lease program will initially operate for the 2014, 15 and 16 seasons.
