American Honda Motor Co., Inc. reveals its up-and-coming launch of the 2012 HRC NSF250R in the US. The NSF250R is newly developed for the FIM GP road racing contest in the Moto3 class. It is powered by a brand new liquid-cooled single-cylinder 249cc four-stroke engine, which has been specifically designed for racing.
This model, which will be distributed worldwide in 2012, will also be qualified in the WERA Motorcycle Road Racing and the USGPRU Moto 3 classes in the USA, among other local racing events.
Among the technical highlights are the front-intake/rear-exhaust configuration with high charging efficiency and an engine layout with the cylinder tilted back 15 degrees to concentrate mass.
In order to develop great power throughout the high-rpm range, the NSF250R combines titanium valves for both exhaust and intake in order to lighten the valve train and reduce friction.
Moreover, the design lessens friction between cylinder and piston, as well as improves durability by applying nickel silicon carbide (Ni-SiC) for the cylinder surface treatment and offsetting the cylinder centerline. The cassette gearbox design was chosen for convenient and fast gearset changes for the six-speed close-ratio transmission, optimizing gear selection over a great range of racing circuits.
This well-balanced and lightweight machine provides a powerful output and superb handling in order to obtain an impressive combination of high performance and rider-friendly characteristics that are well-suited to new racers.
