Kawasaki 2016 KX450F


Lighter and more powerful, the KX450F provides sharper handling and improved circuit performance that will dominate the 450cc motocross class. Significant weight reduction in the engine and chassis make the 2016 KX450F the lightest 450cc Kawasaki Motocrosser, while a slimmer chassis and an even more powerful engine result in sharper handling and increased circuit performance.

The enhancements made to the new 2016 KX450F have maintained the KX design philosophy which stretches back to the creation of the KX brand more than 40 years ago; place mid-level to expert riders on the top step of the podium, every time.

Fuel-injected 449 cm³ liquid-cooled, 4-stroke Single delivers hard-hitting power from low- through high-rpm. The broad powerband and responsive throttle offer a broad spread of torquey response that enables racers to get on the gas and go even from down low. Race-inspired tuning and parts like the high-performance bridged-box bottom piston (a mass-production first when introduced on the 2010 KX450F) ensure top-level performance right out of the box. For 2016, an offset cylinder and numerous changes to the intake system offer even more power, a new exhaust system matches local regulations, and a new accessory KX FI Controller enables map calibration without a PC. Like the chassis, the engine benefits from significant weight savings, with the engine group components weighing almost 2 kg less!
Intake valves have a revised head area. The new design, with slimmer throat angle and reduced recess (similar to valves on supersport models) contributes to increased high-rpm performance. Revised air cleaner shape and silencer construction ensure that FIM and MA noise regulations are met.
Excess material was trimmed from transmission gears and shafts results in a weight reduction of approximately 260 g.
