The 2007 Kawasaki KX450F marked a significant point in Kawasaki's motocross lineage, building upon previous KX models and directly competing with bikes like the Honda CRF450R and the Yamaha YZ450F. This model year saw refinements to the engine and chassis, solidifying its position as a contender in the competitive 450cc motocross class. It aimed to provide riders with a potent and capable machine for tackling demanding tracks and challenging terrain.
At the heart of the 2007 KX450F lies a 449.0 ccm (27.40 cubic inches) single-cylinder, four-stroke engine. This engine configuration offers a strong power delivery suitable for motocross racing. The bike has a dry weight of 99.8 kg (220.0 pounds), contributing to its maneuverability on the track. Fuel capacity is 7.19 litres (1.90 US gallons), sufficient for race durations. This combination of engine size, weight, and fuel capacity made it a serious contender.

With a seat height of 965 mm (38.0 inches), even at its lowest setting if adjustable, the rider sits high, promoting an attacking position. Suspension components are tuned for absorbing jumps and bumps, allowing riders to maintain control and confidence on rough surfaces.
The Kawasaki KX450F 2007 is best suited for experienced motocross riders seeking a competitive machine for racing and track riding. Its powerful engine and focused design make it less ideal for casual trail riding or beginners. It is a machine for those who appreciate a raw, unfiltered motocross experience and are prepared to handle its capabilities. For skilled riders, the KX450F offers a rewarding and capable package.
