2010 CRF250R First Look

here are first look 2010 CRF250R,

, Honda has been the class leader when it comes to 250cc four-strokes. Since its introduction in 2004, the CRF250R has undergone a few changes and managed to remain at or near the top of the class when it came time for the annual TransWorld Motocross 250cc Four-Stroke Shootout. As a package, the bike was powerful, handled well, and had comfortable ergonomics that pleased even the most particular riders. But with the constant pressure to improve, and the age of fuel injection in the 250 class upon us, Honda is now the first of two manufacturers this year to introduce a bike equipped with EFI. With a laundry list of changes other than EFI, this CRF250R is one of the most anticipated bikes of 2010.

THE CHANGES

Looking nearly identical to the CRF450R and actually sharing numerous parts with its larger brother, the CRF250R boasts an all-new chassis, motor, and suspension. Beginning with the motor, Honda’s primary objective was to maintain strong, usable power even when incorporating the Electronic Fuel Injection, which on the 450cc four-strokes has been known to mellow out the power delivery—not something that is desirable in a 250F. While the motor may look similar to previous years, upon closer inspection you’ll actually find much more, as nothing carries over from the previous model—not even the engine cases. A new piston and lighter crank have made it possible for a higher compression ratio and a longer stroke. The position of the cylinder was also changed, tilted back five degrees to improve mass centralization. Up on top, the head features all-new Moto-GP inspired valve spring materials, longer valve springs, and new cam timing. All with the goal of making the CRF pull further and rev higher with stronger power and better durability.
