Well, all that cool info about the 2010 Kawasaki KX 450F is nice .. but we aren’t that much into being ‘gear-heads’ … we just want to ride.



On our brief ride at Pala Raceway, we can say without any doubts – this is a nice ride. Smooth. Fuel injection is smooth too. Smooth pretty much describes this bike all the way around, … motor, suspension, power delivery – all very smooth.



Here’s what Kawasaki says about their bike (and they should be proud):



The 2010 Kawasaki KX 450F provides an ideal platform for riders looking to win races. Its precise aluminum frame, premium suspension components and expert-tuned settings are designed to deliver superb high-speed stability, enabling racers to capitalize on its amazing engine performance. Hole-shot acceleration is delivered by a strong power-band and optimized chassis geometry specifically engineered to maximize rear wheel traction. Monster Energy Kawasaki rider Ryan Villopoto used his new KX450F to win several AMA Supercross and Motocross races, during his first year on a 450.



That’s nice too. All we know is – it looks good, rides good … and we’d like a couple for our garage.
