A carefully engineered, advanced aluminum frame and swingarm give the YZ250 the best handling in the 250 class. |
|
Speed-Sensitive System 48mm Kayaba fork tubes move the transfer control valves (TCV) above the fork springs, so that damping force is controlled by piston speed instead of position. Along with a bigger base valve hole, the result is a smooth ride
and super-precise handling. |
|
Removable aluminum rear subframe constructed of square-section tubing for reduced weight. |
|
Rear, fully adjustable Kayaba shock features a super-light titanium shock spring and reduced-friction Kashima coating of internals. 12.4 inches of travel, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for increased comfort all add up to fantastic rear wheel control and a sweet ride. |
