Kawasaki just introduced its new and improved 2011 KX250F for the summer and Dirt Rider had a chance to get their hands on one. What are the new improvements you may be asking, well there are over 30 changes that they have made for the 2011 bike. The first and probably the biggest change that Kawasaki did on this bike was the introduction of the DFI (Digital Fuel Injection) technology. 
From the naked eye it is hard to see what is different about this bike, but once you get on it there is no question that Kawasaki did their homework with this rocket. The DFI is said to provide a quicker response on the throttle resulting in increased acceleration and torque. I think this is great because one thing that the four strokes were lacking from the two strokes was low end acceleration. The four strokes have been known for a rip roaring top end with a manageable low end, but with the introduction of the DFI my guess is that the two stroke has nothing on a four stroke anymore. The DFI was not the only big change on the 2011 250F, Separate Function Fork was introduced as well.
The Separate Function Fork is a technology that has never been used in motocross before. Using the right fork leg for the springing and preload adjustment and using the left fork leg (shown above) as the dampening adjustment allows for much more variation and control when setting your riding style. Kawasaki also created more compression for the bike by shortening the cylinder and modifying the piston head.
By doing this the engine creates much more pressure in a smaller amount of space resulting in more horses and less weight. I think it is safe to say that the 2011 Kawasaki KX250F is wicked dank. It has been put at the top of its class in terms of technology. There is no doubt in my mind that the 2011 KX250F is a revolutionary bike for the Kawasaki line and it will only get better from here.
