The 2011 Kawasaki KFX 450R is an industry heavyweight, all thanks to its combination of unparalleled racing technology and the feel of natural power riders have on their fingertips.

Looking the part of a natural ATV, the KFX 450R comes with two-piece front and rear “lapped” fenders that make customization painless. In addition, it also has a headlight assembly that can be detached quickly for closed-course races, leaving no compromise as to the aggressive nature of the vehicle.

The Kawasaki KFX 450R shares the engine DNA of the KX 450F motorcross bike, so you can be sure that it’s primed and ready for action. Add the fact that it comes equipped with titanium valves, a highly responsive 32-bit digital fuel injection system that can translate four-stroke power into outstanding thrust, and an electric starter, and you have an ATV that just fits all of the requirements for a four-wheeled ride. To aid in distributing the power of the engine to all four wheels, the KFX 450R makes use of a five-speed transmission that includes a lightweight reverse gear system, allowing riders to quickly and easily extricate themselves from first turn chaos, trail bottlenecks, or any other on-track accidents.

As far as handling is concerned, ATVs are required to be all-world tough and the KFX 450R, with its lightweight all-aluminum frame, has both incredible stiffness and significant strength. It also boasts a low center of gravity and excellent roll resistance for higher corner speeds and race-level handling.

The front suspension design of the ATV makes use of long lower A-arms mounted to a single box-section lower frame tube, paired with dual-rate front springs for excellent rough-terrain handling. Meanwhile, the rear suspension features an adjustable shock with low- and high-speed compression and rebound damping adjustability mated to a cast aluminum swingarm, offering the ideal balance of flexibility and rigidity.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
