Release of the 2010 model YZ250F A motocrosser with new-design aluminum frame and further improved cornering performance

From September 10, 2009, Yamaha Motor Co., Ltd. releases the 4-stroke motocrosser “YZ250F” for the 2010 season mounting a compact high-performance liquid-cooled, 4-stroke, DOHC, single-cylinder 250cc engine on a newly designed aluminum frame in a design that achieves a high level of “quick-turn performance.” (White version release to follow on December 10)
The concept for the 2010 model YZ250F was to maintain the existing model character as a machine with outstanding “quick-turn performance” while adding the new development keywords of “a machine that can be handled at will,” achieving further maturation of the engine and adopting a new “Bilateral Beam Frame” to achieve an even higher level of competitiveness.
The main features include, (1) a new specially designed frame that contributes to outstanding cornering performance, (2) a 5-valve engine with improved characteristics in the low- to mid-speed range for a more linear performance character and (3) exterior parts with smaller surface areas for an impression of lightness and new styling that inspires pride of ownership.
To the Yamaha racing blue version (Deep Purplish Blue Solid E) has been added a fresh red version and also a white version (Purplish White Solid 1) with a more stylish image as a limited order variation.
In Japan, the YZ series models are sold at the dealerships officially certified to sell Yamaha off-road competition models.
