At the heart NSF250R Honda 249cc DOHC single-cylinder is upside down, switch to the next intake of the exhaust port while moving backwards. Titanium valves are used to reduce friction and maximize the output at high rpm. In order to keep the engine and compact to concentrate the mass, the cylinder is called back 15 degrees. Offsetting the middle of the cylinder and adding nickel silicon carbide treatment on the destination cylinder surface to reduce friction and increase durability. shaft balancing machine has been placed on the crankshaft which helps maintain a strong engine and more concentrated mass.

Casing and NSF250 geometry was based from its 125cc predecessor. Its swingarm and the frame has been reconfigured to meet the demands of torsion stiffness of the four-stroke engine. HRC is used up test and CAE analysis to calculate the frame specification. The frame is designed with extra weight of 250 four-strokes in mind that sitting at a claimed 185.2 pounds or 84 kilograms, up from 125 the maximum weight of 80 kilograms. Tweeks to the chassis must provide stability during braking, as well.
Close-ratio six-speed gearbox tapes stacked design that allows for the gear ratio to be exchanged out a little easier to meet the demands of racing in different circuits during the MotoGP season. The basic structure of the suspension equal RS125R.
Former world champion Alex Criville GP 500 demo will complete a lap on NSF250R tomorrow and on Sunday before the race MotoGP in Barcelona. Sales of new road racing bike that is planned to commence in December 2011. Initial MSRP 23,600 Euros (U.S. $ 34,070).
HRC Executive Vice President Shuhei Nakamoto and Development Project leader NSF250R Kurayoshi Yoshiyuki Honda Racing Corporation launched new Moto3 motorcycle at a press conference Montmelo.

The 34-year period and maintained a number of riders racing. We have enjoyed much success with RS125R and we hope this new engine will give the same story. Dani Pedrosa and Andrea Dovizioso become World Champion this bike ride and our goal is again to give young riders a good racing machine to help them learn the basics and gain experience to one day reach the upper class, “said Nakamoto in HRC PR.
