Previously called the NRS250 (NRS for “Next Racing Standard”) The Honda NSF250R will be offered to teams looking to race the Moto3 World Championship which will replace the current two-stroke 125cc class in 2012.
No official specifications were released but under Moto3 regulations, the NSF250R is limited to a 250cc single-cylinder engine with a bore of up to 81mm and a maximum rev limit of 14000rpm.
According to a statement from Honda Racing Corporation, the NSF250R inherits elements from the Honda RS125R 125 Grand Prix race bike. The RS125R has captured 130 Grand Prix race wins with nine riders winning the world championship on the RS125R including current Honda factory MotoGP riders Dani Pedrosa and Andrea Dovizioso. The RS125R has not been a familiar site on the grid in recent seasons however with only one rider, Marcel Schrötter of Interwetten Honda race team, competing in the entire 2010 125cc World Championship season on the RS125R.
