Thread: 2011 Kawasaki KX250F

The easy and highly efficient DFI system integrates a compact and lightweight Electronic Control Unit (ECU), a 43mm throttle body, a lightweight aluminum fuel pump and an ultra-fine atomizing injector. Editors from apex motorcycle periodicals test ride the new 2011 Kawasaki KX250F with fuel injection at Budd's Creek, MD.

Check out Ultimate Motor Cycling's SELF Reid Davis at 1:36. For 2011, the aim was a yet faster and additional rid able KX250F. The big reports are the adding up of Digital Fuel Injection (DFI) that not only aids generate stunning and additional utilize able power, but as well makes tuning a lot easier proposal.



You'll find extra important modifies beyond downstream, for example higher compression at the present 13.5:1 vs. 13.2:1 by a customized cylinder and changes to the peak of the elite Bridged-Box Bottom piston. Transmission and ultimate-drive ratios have been distorted a little to match the engine's spanking response, and a customized shifting mechanism permits you to access those speeds more simply and smoothly.
The 2011 Kawasaki KX250F chassis has been manipulated each bit as methodically as the engine with Kawasaki's new Separate Function Fork (SFF) leading the list of alters. Different a conservative fork design, where each fork leg handles equally springing and damping, the SFF separates spring and damping functions for enhanced performance, 25 percent less friction, lower weight and easier adjustability.

The right leg lodges the spring side of the equation, integrating a larger main spring/rod assembly than traditional forks, plus a small amount of oil for lubrication. Spring preload is now adjustable via a blue-anodized adjuster on the right leg's cap.
