Features

Chassis, Ergonomics & Styling

  • THE ADVANTAGE IS YOURS: With agile handling, a strong and lightweight chassis and exclusive ERGO-FIT® technology, you’ll experience an unmatched race-winning advantage on the KX™450SR. Stand out from the crowd with factory edition styling, featuring Monster Energy® Kawasaki race team-inspired graphics and HINSON clutch cover.
  • PRECISE BALANCE: Stay ahead with a lightweight aluminum perimeter frame and swingarm that provides overall rigidity balance which contributes to precise cornering. Enjoy a front-end feel that’s predictable while maintaining maximum traction through the rear wheel.
  • DURABILITY ELEVATED: A D.I.D Gold Chain and RENTHAL Rear Sprocket handle gearing duties while D.I.D Dirt Star ST-X Rims offer enhanced style and durability to the wheelset.
  • PERFECT FIT: The XTRIG ROCS (Revolutionary Opposed Clamping System) clamps the upper fork tubes from opposite directions helping to reduce inner tube distortion and allowing the fork to flex naturally. The PHDS (Progressive Handlebar Damping System) absorbs vibrations while maintaining steering precision. This also increases the available handlebar mounting which can be adjusted to 12 different positions. A factory-style aluminum Renthal® Fatbar® handlebar completes the elite package.

Next-level Technology

  • RIDE CONFIDENTLY: Offering quick, reliable starting, advanced braking power and backed by decades of championship-proven experience, the KX™450SR delivers superior technology designed to inspire confidence from the gate drop to the finish line.
  • UNMATCHED STOPPING POWER: Incredible acceleration capability and next-level stopping power combine to give you ultimate control on the track. In the front, an oversized 270mm Braking® petal disc with a dual-piston caliper delivers sharp response and a strong consistent feel. In the rear, a large-diameter 250mm Braking® petal disc complements the front for race-ready performance.
  • START AGAIN: An engine stall can make or break a race. Which is why with a compact and lightweight Li-ion battery, supported by an automatic centrifugal decompression system, you’ll be back in the race with a push of a button.
  • LIGHT PULL & SELF-ADJUSTING: A coned disc-spring hydraulic clutch offers light clutch pull and a wide engagement range. Large diameter plates provide enhanced fade resistance.

Power & Performance

  • ONE-OF-A-KIND: The all-new KX450™SR is designed for serious competitors seeking race-wins. Featuring elite-level racing components, special tuning and design updates inspired by the Monster Energy® Kawasaki race team, this limited-edition Special Racer boasts elevated performance and factory racer looks. Performance gains come thanks to updates* to the engine, exhaust, suspension, engine mapping, and wheels.
  • PUSHING TO FIRST: The 449cc engine features polished intake ports and exclusive engine ECU/FI settings for increased engine performance*. While the engine and titanium race exhaust system deliver increased engine performance and reduced weight.
  • POWER TO THE GROUND: Start strong with a factory-style launch control system that helps put the bike’s power to the ground, maximizing the acceleration potential from the gate drop to the holeshot.
  • KEEP IT LIGHT: Experience increased engine performance and lighter weight with a Pro Circuit titanium race exhaust system

Race-ready Suspension

  • SHOW THEM HOW IT’S DONE: Enjoy smooth action, firm damping and optimal traction with the highly adjustable suspension package on the KX™450SR.
  • RACE READY: Experience unmatched suspension performance with the highly adjustable 48mm KYB Coil Spring Front Fork. Large-diameter inner tubes with DLC coating deliver smooth, low friction, action and allow the use of large damping pistons for race-winning performance.
  • GAIN TRACTION: The adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping and adjustable preload come thanks to the Uni-Trak® rear suspension system, featuring KYB shock. The result is unmatched damping and rear-wheel traction.
