Features

Brakes

  • 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.

Electric start and hydraulic clutch

  • RELIABLE STARTING: Conserve energy and ride smarter with an electric start and hydraulic clutch. A lithium-ion battery ensures strong and reliable starting performance, eliminating the need for a backup kickstarter. The hydraulic clutch offers a direct feel and consistent actuation even as engine temperatures rise while also offering a light pull at the lever.

Ergo-fit® & ergonomics

  • 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.

Features

  • Lightweight frame and swingarm.
  • Launch Control Mode.

Powerful engine

  • BUILT TO WIN: Delivering strong, responsive power, the engine of the KX™450 motorcycle features a finger-follower valve train. Crafted with the same design used by Kawasaki factory race teams, the 449cc engine produces broad torque and strong power across the entire rev range.

Suspension

  • RACE-READY SUSPENSION: 49mm Showa Coil Spring Front Fork combined with A-KIT Technology deliver superb 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 ensures optimal rear-wheel traction.
