    The wait is finally over, as Honda has completely taken the wraps off its 2012 Honda NSF250R Moto3 race bike. Launched at the Catalan GP today, the 250cc four-stroke machine will be one of several options aspiring MotoGP riders will pilot around in the Moto3 Championship. The new NSF250R incorporates a front-intake/rear-exhaust configuratiom, while the cylinder has been tilted back 15° to help concentrate the bike’s mass.

    Titanium valves help power throughout the rev range, and the cylinder design reduces friction between piston and cylinder by offsetting the cylinder centerline and applying nickel silicon carbide (Ni-SiC) for the cylinder surface treatment. Matted to the motor is a six-speed gearbox, while the frame is based off the RS125R design, with modifications to suit the power delivered by the four-stroker. Total cost: ?23,600, VAT included (Spain). Full technical specs are after the jump.

                              Launch of the NSF250R Commercial Road Racing Machine

                                           

    TOKYO, Japan, June 2, 2011 — Honda Racing Corporation will launch the NSF250R, a newly developed machine for the Moto3 class that will be added to the FIM Road Racing World Championship Grand Prix (WGP) in 2012. Sales of the new vehicle are planned to start in December 2011.

    In developing the NSF250R, Honda took the “Next Racing Standard” as its development concept and reaped the benefits of racing technology cultivated in the RS125R, thereby achieving a high-level combination of outstanding controllability and racing competitiveness.
The liquid-cooled, 4-stroke, single cylinder, DOHC, 249 cc engine was specifically designed for Moto3 to be lightweight and compact while delivering high output. To achieve this high output together with excellent responsiveness, the machine incorporates a front-intake/rear-exhaust configuration with high charging efficiency, while adopting a layout with the cylinder tilted back 15° to concentrate mass.

    To ensure power delivery all the way through to the high rpm range, the NSF250R adopts titanium valves for both the intake and exhaust to reduce friction. Furthermore, the design reduces friction between piston and cylinder and improves durability by offsetting the cylinder centerline and applying nickel silicon carbide (Ni-SiC) for the cylinder surface treatment. The easily replaceable cassette design selected for the close-ratio 6-speed transmission, allows gear selection to be optimized over a large variety of racing circuits.

    The frame ensures a degree of freedom in cornering and nimbleness that matches and goes beyond the RS125R by revising the rigidity balance and the shape while inheriting the compactness of the RS125R. Even though the basic structure of the front and rear suspension is the same as the RS125R, the NSF250R-exclusive settings produce a machine with excellent riding stability.

    The cowling makes the NSF250R the equal of the RS125R in aerodynamic performance, while a cooling duct on the under cowl improves the engine’s cooling performance.

    As a new-generation road racing machine that complies with Moto3 regulations, the NSF250R will help revitalize road racing while meeting the expectations of road racers.

    Honda has done a pretty good job of teasing out its HRC NSF250R, which is set to race in the Moto3 Championship in 2012. Replacing the 125GP, Moto3 class is based around four-stroke 250cc race bikes, and should be a more affordable and leveling playing field for new riders to enter into GP racing. HRC has teased us with images and videos of the new NSF250R, which takes its core cues from the its RS125R predecessor (both current factory Honda riders Dani Pedrosa and Andrea Dovizioso won their lower Championships on the Honda RS125R).

    Expect more media goodness in Barcelona in two weeks’ time, as Honda plans on unveiling the bike the Thursday before the Catalan GP. Following its launch, Alex Crivillé will pilot the bike around the Spanish track, with another exhibition lap to take place after the MotoGP warm-up session. For your smokers, soak up this last season of 125GP racing, as two-stroke racing is about to go the way of the dinosaur.
