Honda has finally took the wraps off the 2012 NSF250R Moto3 race bike. The NSF250R is powered by a liquid-cooled, 4-stroke, single cylinder, DOHC, 249 cc engine which 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.
