PRODUCTION RACER KTM RC 250 R – THE MOTO3 WORLD CHAMPION 2012!

There was only seven months between the presentation of Moto3 winning aggregate in Hangar 7 in Salzburg, Austria at the beginning of October 2011 and Sandro Cortese’s premiere win on the KTM RC 250 GP in Estoril, Portugal. But this success is no mere product of coincidence but of the systematic implementation of the project. As well as the rider world title through Cortese and the manufacturer’s world title for KTM in the first year of the Moto3 competition, the results of the other four KTM riders and of the four KALEX-KTM riders was an impressive display of this knowhow.

It is on the basis of the consistent speed of the nine KTM riders that the KTM racer is being further developed for 2013. Both the production racer and the Red Bull MotoGP Rookies Cup bike will be on the start next season so that customer teams and up-and-coming riders are able to profit from this development in the future. Both machines are direct offshoots of the KTM Grand Prix motorcycle and both are developed under the technical direction of Wolfgang Felber.

Stefan Pierer (KTM CEO): “All of KTM’s knowhow come together in the Moto3 Grand Prix motorcycle and it represents the technology from offroad and that which has already been proven in road racing. Internally there was a knowhow transfer between R&D, motor sport and production development while ‘externally’ Moto3 development profited from both KTM subsidiaries and the companies of Cross Holding. The KTM involvement in motorcycle racing at the highest level reinforces the brand positioning in the street bike segment and is an advertising medium for our latest range of smaller displacement street bikes!”

Pit Beirer (Head of KTM Motorsport): “After we had a real holeshot start to the season we have now established ourselves in the new Moto3 class as one of the major players and we even succeeded in winning the world championship title in the premiere season. Now for 2013 we want see our motorcycles even more deployed in the Moto3 World Championship. KALEX continues to remain our exclusive chassis partner and will be supplied with our engines. We are confident that we will be able to offer a good package and would be delighted if teams and riders are on the start of the World Championship races with the KTM Production Racer!”

Wolfgang Felber (Head of KTM Customer Racing Sport): “The basis of the Production Racer is not much different to our Grand Prix motorcycle. The GP bike is only adapted to suit the current Moto3 regulations, for example it runs with the regulation Dell’Orto electronics unit, has a maximum of 14,000 revolutions and has an Akrapovic exhaust system that allows 115 dB. OZ magnesium wheels, a factory braking system with dual brake disks from Brembo in the front and WP Suspension elements all save weight – but basically these are also components that can all be fitted to the RC 250 R Production Racer!”
