The CBR250R is equipped with a newly-developed liquid-cooled 250cc 4-stroke 4-valve single-cylinder DOHC engine coupled to a constant mesh 6-speed return transmission. The full-cowl body presents a highly advanced design full of functional beauty. The light and compact frame, made of a highly-rigid diamond shape in a truss structure, offers agile handling and steady maneuverability, while the cowl design enables optimal control of the wind toward the engine or the rider. Performance is enhanced by adopting the electronically controlled fuel injection system (PGM-FI), without sacrificing high environmental performance that meets Euro 3 emission standards.
In the area of safety technology, the CBR250R incorporates Combined ABS (a world first for a 250cc-class motorcycle), which combines a front/rear wheel interlocking brake system with an anti-lock brake system (ABS). The Combined ABS makes vehicle movements more stable during braking by bringing together a Combined Brake System (CBS, a front- and rear-wheel interlocking braking system) and an Anti-lock Brake System (ABS, a braking system that prevents wheel lock during sudden braking or under unfavorable conditions). The rear suspension adopts a Pro-link suspension with five-position preload adjuster, allowing adjustment to respond to the rider's preferences, riding in tandem, and other demands. Other safety features found only on larger motorcycles such as easy-to-grasp separate left/right rear grips come as standard.
Sales in Thailand commence on December 10, with a special CBR Platinum Package consisting of the Honda Roadside Assistance service and one-year Free Maintenance Coupon for customers who purchase before December 31.
ENGINE
The CBR250R engine was developed by aiming at a global single-cylinder engine that transcends regions, while being sporty and eco-friendly at the same time, with a look ahead at the next generation.
What should a next-generation liquid-cooled 250cc single-cylinder engine that is also ecofriendly be like?
What should the output characteristics of a 250cc single-cylinder sport bike be when the comfort and the ease of handling that can satisfy customers all over the world are taken into account?
How can an engine that is light and compact and yet has a high-quality feel be able to support the ride as the rider wants it?
With these questions in mind and aiming at the output characteristics that would realize a light and sporty maneuverability in the complete vehicle while retaining the advantages of fuel economy and ease of handling of conventional single-cylinder engines, we have developed a new 250cc single-cylinder engine that is light and compact and runs smoothly not just at low rpm but also in the high rpm range.
CHASIS
Our development objectives for the frame and chassis include fusing flexibility with a rigid feel at a high level through mass centralization and satisfying the sporty feel a rider gets the moment they mount the bike. Development also aimed to provide a basic riding performance that covers body size, dimensions, driving stability, and riding position; these factors were optimized for riders of all kinds from beginners to experienced riders so that they can feel the fun of maneuvering -a fundamental element of motorcycle riding. A rider should be able to use the bike casually in everyday life, go touring at times, and enjoy a sporty ride at other times.
More specific objectives included the following:
• A frame that will realize agile handling and steady maneuverability characteristics as a 250cc full-cowl sport model
• A sporty riding position that takes into account a level of comfort and ease of handling that will satisfy customers around the world
• A secure suspension capable of supporting the ride that the rider wants and maximizing bike performance
• The first introduction in its class of Combined ABS, which provides customers with a sense of security
