It's pretty common for manufacturers to present new models amid a flurry of acronyms, and the 2011 Kawasaki KX250F is no exception. DFI and SFF are two new technologies that top the list of over 30 new features for the latest quarter-liter motocrosser. DFI stands for Digital Fuel Injection, the battery-less system intended to take the KX to the next level in terms of throttle response and reliability. The other standout acronym represents the Kawasaki-exclusive Separate Function Fork, with the spring support in the right fork leg and the damping circuitry in the left. Other notable updates include a higher compression ratio, redesigned five-speed transmission and a higher-volume muffler, which would make it seem as though Kawasaki has addressed every complaint that anyone had about the '09 KX250F.
