Absolutely nobody can exceed the championship legacy of Kawasaki and the KX™ motorcycle. KX owns more combined professional 250cc and 450cc AMA National Motocross and Supercross titles than any other manufacturer.
The first few seconds of the race are critical for getting ahead of the pack. With a more powerful engine and updated technology, the time from the starting gate to the first turn just got a lot quicker.
The KX™450 combines unmatched engine power, suspension technology, and braking ability to overtake the competition on any part of the track.
Improvements in engine, chassis and traction performance result in faster lap times for the
2019 KX™450.

Increased peak power and a flatter torque curve come thanks in part to:
Reduce lap times with Kawasaki’s first hydraulic clutch on the KX™450. The new clutch offers a more direct feel and an easier pull for lighter lever action, helping to reduce riding fatigue. As the clutch heats up during heavy use, minimal change in clutch play provides a more consistent and direct feel.
Factory-style launch control system helps to put the bike’s power to the ground for maximum acceleration at the start of the race, making the holeshot yours for the taking.
A flatter torque curve makes it easier to get on the gas sooner, delivering smooth and powerful acceleration to pass the competition and keep you ahead of the pack.
The KX™450 delivers major stopping power when you need it most thanks to the new larger-diameter 250mm petal-shaped BRAKING® rear brake rotor that complements the oversized 270mm petal-shaped BRAKING® front brake rotor. A new front brake master cylinder offers better initial control and braking performance, while the new rear brake master cylinder and hose have been revised to reduce weight.
Updates to the KX™450 contribute to smooth suspension action and a better ride feel.
Improved damping, increased traction and more precise rear suspension tuning come as a result of:
Redesigned bodywork better facilitates rider movement.
ERGO-FIT® adjustable handlebar mounting system and footpegs enable the perfect fit to help you comfortably ride with confidence.
Choose engine settings to suit your riding style or track conditions with KX™450 DFI® couplers. This plug-and-play style system allows riders to quickly and easily select from three different pre-programmed fuel injection and ignition mapping settings. Fine tune your ECU setting with factory precision with the KX FI Calibration Kit*, featuring a handheld controller that enables riders to adjust fuel mapping and store presets for various track conditions without a PC.

The updated lightweight aluminum perimeter frame and swingarm increase overall rigidity balance and contribute to precise cornering through excellent front-end feel and increased traction at the rear wheel.
The new lighter footpegs are 5mm wider and positioned 3mm farther rearward, offering excellent grip and making it easier to weight the pegs.
