On Thursday in Catalunya, Honda Racing Corporation presented its new NSF250R 4-stroke machine, for use in the new Moto3 grand prix class (see below for further pictures).

Moto3, which will feature 250cc four-stroke machines, is to replace the 125cc (two-stroke) grand prix class from 2012.

"The concept of the NSF250R represents an important step forward for us, to create the next racing standard," said Development Project Leader Yoshiyuki Kurayoshi.

"The main characteristics are a lightweight and compact machine, with high power and high efficiency, aiming to revitalise the road racing popularity.

"It is a compact machine that weighs 84 kilos, has a maximum power of 35.5 kw, 13,000 rpm and a fuel capacity of 11 litres".

I'm very happy to be here in Catalunya launching the new machine that Honda has produced to compete in the Moto3 category next season," added HRC Executive Vice President Shuhei Nakamoto.

"From the MT125R of 1976 to the RS125R, Honda has produced many market racing machines during this 34 year period and nurtured a number of racing riders.

"We have enjoyed much success with RS125R and we hope this new machine will provide a similar story.

"Dani Pedrosa and Andrea Dovizioso became World Champions riding this bike and our aim is again to give young riders a good racing machine to help them learn the basics and gain experience to one day reach the top class.

"Our greatest joy would be for the machine to serve as a springboard in creating future MotoGP Champion riders".

HRC will sell the NSF250R machine, engine and spare parts in Europe and other countries through the Honda Motorcycle dealer network and also through GEO Technology, an official supporter of the Moto3 class.
