Advanced Technology

• RIDE CONFIDENTLY: Offering quick, reliable starting, and advanced braking power backed by decades of championship-proven experience, the KX™450SR motorcycle delivers superior technology designed to inspire confidence from the gate drop to the finish line.
• POWER IN YOUR HANDS: Enjoy power mode selection at the push of a button located on the handlebar of the KX™450SR motorcycle. This feature allows riders to switch between 2 power modes (Normal or Aggressive response) quickly and easily. Riders can select between Normal and Aggressive response to suit riding conditions or preference. The Aggressive mode is exclusive to the KX™450SR and was developed with feedback from racers, making this model well-suited to competitive riding.
• KAWASAKI TRACTION CONTROL: The KX™450SR motorcycle features Kawasaki TRaction Control (KTRC) at the push of a button. Using the traction button (T) on the left handlebar switch, riders can quickly and easily select from 2 levels (Weak or Strong) of traction control to suit riding conditions and preference. Riders may also elect to turn the system off.
• POWER TO THE GROUND: A factory-style launch control system helps put the KX™450SR motorcycle’s power to the ground for maximum acceleration. By pushing the Mode and Traction buttons simultaneously, riders activate the launch control system designed to deliver efficient race starts in low-traction conditions, making the holeshot yours for the taking.
• SMARTPHONE CONNECTIVITY: Thanks to smartphone connectivity, riders can adjust engine mapping straight from their phones via RIDEOLOGY THE APP KX™, without any extra equipment. The app also provides KX™ FI Calibration to check fuel volume and ignition timing, engine monitoring for checking engine metrics, a maintenance log for recording memo-style logs, and many more useful functions.

Chassis, Ergonomics, & Styling

• THE ADVANTAGE IS YOURS: With agile handling, a strong and lightweight chassis, and ERGO-FIT® adjustable components, you’ll experience an unmatched race-winning advantage on the KX™450SR motorcycle. Stand out from the crowd with factory-edition styling, featuring Monster Energy® Kawasaki race team-inspired graphics, Lime Green handlebar pad, Metallic Magnesium Gold cylinder head cover, and a Hinson clutch cover.
• PRECISE BALANCE: Stay ahead with a lightweight aluminum perimeter frame and swingarm that provide fantastic overall rigidity balance and contribute to precise cornering. Enjoy 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.
• ADVANCED STOPPING POWER: Next-level stopping power matches incredible acceleration capability. The high-performance brake system features drilled Braking/Sunstar discs (270/240mm) paired with a Brembo caliper and master cylinder at the front and a Nissin caliper and master cylinder at the rear. The high-performance system offers increased control during braking, contributing to enhanced corner entry.

Power & Performance

• LIMITED-EDITION RACER: The KX™450SR motorcycle is designed for serious competitors seeking race wins. Featuring elite-level racing components, special tuning, and design inspired by the Monster Energy® Kawasaki race team, this limited-edition Special Racer boasts elevated performance and factory racer looks.
• MORE POWER TO DOMINATE: Thanks to polished intake ports, a high-performance Pro Circuit exhaust, specialized ECU FI settings, and tuning, the KX™450SR motorcycle offers considerably stronger power and torque at mid- to high-rpm than the base KX™450 motorcycle.
• KEEP IT LIGHT: Experience increased engine performance and lighter weight with a Pro Circuit titanium race exhaust system.
• 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.

Race-Ready Suspension

• SHOW THEM HOW IT’S DONE: Enjoy smooth action, firm damping, and optimal traction with the highly adjustable Showa suspension package on the KX™450SR motorcycle. The Showa suspension package on the KX450SR is inspired by the machines ridden by the Monster Energy® Kawasaki race team with optimized settings to achieve higher performance, smoother suspension action, and provide a plush feeling.
• RACE READY: Experience unmatched suspension performance with the highly adjustable 49mm Showa Coil Spring Front Fork. Kashima Coating creates a hard, low-friction surface on the fork's outer tubes. Large-diameter inner tubes with titanium 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 a Showa shock with Kashima Coating outer tube. The result is unmatched damping and rear-wheel traction.
• PERFECT FIT: The XTRIG ROCS-TECH (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 comes standard.
