2017 Kawasaki KX™450F

THE KAWASAKI DIFFERENCE

THIS IS OUR PROOFThe 2017 KX™450F motorcycle is the most powerful, lightweight, and agile KX450F ever. Developed from the highest levels of racing, this championship bike has advanced technology sourced straight from the world’s premier race team—another reason why the KX450F is The Bike That Builds Champions.

CHAMPIONSHIP-PROOVEN POWERThe 2017 KX™450F motorcycle is lightweight and powerful due to innovative race-proven components. Pick a category to start exploring.

Features may include:

ENGINE- Race-team-inspired Bridged-Box Bottom piston is lightweight and designed to match intake valves to optimize combustion efficiency for maximum performance at all rpms

EXHAUST- Exhaust header features an integrated resonator for crisp throttle response at low RPM and reduced exhaust sound level

INTAKES- Rear seat intakes ensure the clean airflow and contribute to improved throttle response

• High flow airbox with rear intake channels for improved engine power

CHASSIS AND BODYWORKThe slim, lightweight, aluminum perimeter frame and revised triple clamps contribute to agile handling while a flat seat profile and integrated bodywork facilitate easy rider movement and a championship fit.

SLIM, LIGHTWEIGHT CHASSIS- Lightweight aluminum perimeter frame for sharp handling

• Redesigned triple clamp offers improved stability on corner entry to allow quicker turn-in.
• Slim frame spars and narrow shrouds allow easier rider movement
• Optimized swingarm rigidity for maximum rear wheel traction
• Lightweight bodywork features Kawasaki’s first in-mold graphics for a durable, aggressive look
• Lightweight bodywork with smooth, seamless surface at the rider's contact points.
• The KX graphics are now molded into the shrouds for greater longevity and an ultra-smooth outer surface.

ADJUSTABLE ERGONOMICS- Adjustable four-piston handlebar moves towards or away from your body

• Two-position adjustable footpegs help reduce knee angle when seated

SHOWA SFF-AIR TAC FORK- Lightweight design with tuned rigidity to match chassis dynamics and optimize front end feel

• Features low-friction fork seals and optimized valve settings for smooth action and progressive damping
• STEP 1: Set inner chamber air pressure - The pressure in this chamber affects the overall fee across the entire stroke
• STEP 2: Set the pressure of the outer air chamber - The outer chamber affects the last third of the travel so you can adjust the level of bottoming resistance.
• STEP 3: Set the pressure of the balance chamber- This will adjust fork ride height and damping feel at the initial part of the stroke
• STEP 4: Final set-up step - Open the bleed screw on the left forks cap. This equalizes pressure with the atmosphere
• STEP 5: Fine-tune damping - Adjust rebound and compression damping to best suit riding conditions and personal preference

ADVANCED FUEL MAPPING TECHNOLOGYThe KX™450F motorcycle features several advanced ignition and fuel-mapping systems for precise adjustability.

KAWASAKI GENUINE ACCESSORY- Handheld FI calibration controller eliminates need for laptop and 12V battery at the track

• Allows the user to adjust fuel and ignition settings for ultimate performance
• Can store up to 7 preset maps for different
