Kawasaki Ninja ZX-6RR picture and feature

Features and Benefits:

Four-Cylinder 599cc Engine

• Reshaped combustion chambers and redesigned piston crowns help produce more power
• Molybdenum coating added to piston skirts to reduce friction and mechanical loss, contributing to the ZX-6RR’s high-revving nature
• Intake and exhaust valves are larger for better breathing at all rpm
• Camshaft profile has higher lift for more performance
• Gear ratios for the oil pump changed to reduce mechanical loss
• Cut-outs added to the cylinder skirts to reduce pumping loss
  

Crankcase

Crankcase is light and rigid, allowing piston oil jets to be positioned closer to pistons

Optimal Intake

• Short intake and exhaust valves reduce weight and improve high-rpm performance
• Larger intake valves help increase performance
• Single springs of oval-shape are lighter providing improved intake valve control at high rpm
• Stepped spring seats replace previous plain type to better stabilize the valve springs
  

Fuel Injection System

• Large-bore 38mm throttle bodies produce high engine output and low emissions
• Sub-throttle bodies ensure smooth, linear power characteristics
• New twin injectors improve cylinder filling for more power
  

Six-Speed Transmission w/Clutch Back-Torque Limiter

• Closer gear ratios for 2004 provide for more aggressive, competition-style performance
• Clutch back-torque limiter helps prevent wheel hop during quick deceleration
  

Digital Ignition

• 32-bit high-speed microprocessor-controlled timing is ultra-responsive

Lightweight Exhaust System

• Light exhaust system contributes to engine performance
• Stainless muffler housing improves catalyzer performance and reduces emissions
  

KLEEN™ (Kawasaki Low Exhaust Emission) System

• Helps keep exhaust emissions environmentally friendly
• KCA (Kawasaki Clean Air) system routes fresh air to the exhaust ports for reduced exhaust emissions
  

Ram Air Intake

• Centrally located ram-air duct reduces number of parts and weight to improve intake efficiency
• Greater resistance to wind side-drafts
  

Pressed Aluminum Perimeter Frame

• Rigid aluminum frame delivers crisp and stable handling
• Centrally mounted Ram Air duct is integrated with steering head to reduce weight and improve Ram Air efficiency
• Lightweight aluminum sub-frame facilitates maintenance
• Adjustable swingarm pivot for fine-tuning handling
• Steering head bearings use ball bearing type for light, responsive steering
• Threaded steering damper mount incorporated into left frame spar
  

Aerodynamic Cowling

• Race-inspired fairing and bodywork give the machine a distinctively racy look
• Fairing offers an exceptionally low drag coefficient for slippery aerodynamics
• Central Ram Air duct gives the front of the bike an aggressive identity
• Lightweight and powerful dual multi-reflector headlights provides exceptional visibility
  

41mm Inverted Kayaba Fork

• Fully adjustable fork runs stiff tubes for high fork rigidity and superior steering feedback
• Top-out springs and adjustable spring preload are fitted for stable performance throughout the stroke range
• Super-hard DLC (Diamond-Like Carbon) coating added to inner fork tubes to reduce friction
• Revised damping for improved action
  

Bottom-Link UNI-TRAK® Rear Suspension

• Nitrogen-gas charged Kayaba shock with piggyback reservoir is fully adjustable for rebound and compression damping
• Shock utilizes a threaded collar spring preload adjuster
• A top-out spring on the rear shock improves shock action
• Stepless damping adjuster with check valve instead of needle valve for improved damping
• Adjustable ride height with 1mm shims

Stopping Power

• Radial-mounted, four-piston, four-pad front brake calipers
• Four independent brake pads are used in each caliper for more even wear and improved heat resistance
• Semi-floating 280mm steel front disc rotors are 6mm thick for high heat capacity and mount on flat disc carriers without offset for reduced weight
• Brake lever is five-way adjustable
• Small diameter rear brake disc measures 220mm in diameter without offset for low unsprung weight
• Front brake hose routing eliminates interference with radiator
  

Instrument Cluster

• Instrument cluster features a bar-type LCD tachometer, digital LCD speedometer, programmable shift indicator light and stopwatch-style 99 lap timer
• Cluster also includes digital temp gauge, clock, tripmeter and comprehensive range of indicator lamps
  

Details

• Handlebar, seat and footpeg location enhance a track oriented riding position
• One-piece forged aluminum handlebars
• Ergonomically shaped seat and tank allow rider to mold to bike
• LED taillight is very light, highly compact, very durable and looks exceptionally cool
• Tamper resistant ignition switch
• Quick-detach rear seat allows easy mounting of standard aerodynamic single-seat cover
• Extruded aluminum swingarm with internal ribbing offers strong, torsional rigidity and low weight
• Friction-reducing sealant on the front brake caliper pistons improves brake feel
• Lime green coating added to side plates of X-ring drive chain for cool, racy look
