Honda's NSF250R will be one of the main contenders in Moto3 next season.

The full regulations for the Moto3 World Championship that is set to be introduced in 2012 have been released.

Taking over from the two-stroke 125cc Grand Prix category, the 250cc four-strokes will be the final step in the transition to four-strokes for world motorcycle racing.

Unlike the Moto2 class, the Moto3 regulations are open to various manufacturers, with both Honda and KTM unveiling engines specifically built for the class to date.
