DOMINATE THE HOLESHOT
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
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.
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.
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.
