TOP FEATURES

DOMINATE THE HOLESHOT
RELIABLE STARTING
Being able to restart your engine quickly after a stall can make or break a race. Powered by a compact and lightweight Li-ion battery and supported by an automatic centrifugal decompression system, now all it takes is the push of a button.

POWER THROUGH THE FINISH
Delivering strong, responsive power across the entire rev range, the 449cc engine features a finger-follower valve train designed by Kawasaki’s World Superbike engineers. 

EVERY SECOND COUNTS
Factory-style launch control system helps put the bike’s power to the ground for maximum acceleration at the start of the race, making the holeshot yours for the taking.

MASTER THE PASS
RACE READY
49mm Showa Coil Spring Front Fork combined with A-KIT Technology deliver excellent suspension and handling. Large-diameter inner tubes allow the use of large damping pistons for race-winning performance while a large-diameter front axle improves front-wheel traction.

CHAMPIONSHIP PROVEN
The Uni-Trak® rear suspension system with adjustable dual-range (high/low-speed) compression damping, adjustable rebound damping and adjustable preload ensures optimal damping and rear-wheel traction. 

PULL AHEAD
A flat 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.

ADVANCED STOPPING POWER
The most advanced KX™450 motorcycle yet features stopping power to match its incredible acceleration capability. Up front, an oversized 270mm Braking® petal disc with dual-piston caliper offers sharp response and a strong, consistent feel. In the rear, a large-diameter 250mm Braking® petal disc complements the front for race-ready performance.

SHAVE LAP TIMES
BALANCE MEETS PRECISION
Lightweight aluminum perimeter frame and swingarm provide overall rigidity balance and contribute to precise cornering through predictable front-end feel and maximum traction at the rear wheel.

GET A GRIP
Wide footpegs offer excellent grip making it easier to weight the pegs.

INELY TUNED POWER
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.

LIGHT PULL & SELF-ADJUSTING
Hydraulic clutch offers a direct feel and an easy pull for light lever action, helping to reduce riding fatigue. As the clutch heats up during heavy use, minimal change in clutch play provides a consistent and direct feel.

SHAVE LAP TIMES
PERFECT FIT
Find your best performance with the Kawasaki ERGO-FIT® advantage. Four handlebar positions and two footpeg positions allow you to tailor the KX™450 motorcycle to your body size, riding style and preference. Wide footpegs ensure excellent grip for optimum comfort and control.
