2008 Kawasaki KX 450F Features
Engine
– 449cc liquid-cooled, DOHC, four-stroke single with lightness, oxidized membrane treated titanium valves
– Top-acceleration assist cam engine rev quickly
– Revised piston oil-jet cooling
– Fifth bolt added to cover oil pump to better seal
– Double overheads, camshafts have a slight soft-nitride surface treatment for the wear and high reliability rpm
– Special coating on the intake ports to improve the effectiveness of admission to all rpm
– Titanium 36mm and 31mm admission of exhaust valves aluminum spring restraint and double valve springs progressive alternative reduce the weight and height of the cylinder and help ensure reliable valve control at high tr / Min
– Maintenance-free screw with automatic adjusting cam chain
– Low-friction coating on the piston skirt
End Lower
– New equipment rod has a difficult surface to reduce friction
– New wedge-shaped crank Web combined and a new heavy flywheel to reduce vibration and increased low-end performance
– Pump oil has revised a gear ratio and 2 mm larger rotor to increase the flow of oil
– Unique respite crankcase ventilation system by balancing shaft located in the crankcase, which allows the engine to rev more freely
From
– Features highly reliable self-decompression system, the double weight decompression centrifuge system mounted on the exhaust came easy start, and its simple construction contributes to ensuring reliability
– System hot start facilitates begins when the engine is hot, and the lever hot start is unitary with the clutch lever
The exhaust
– New joint heat and support thicker chicane help increase reliability
– Grand 41mm top exhaust titanium for even more power
– Lightweight, head tapered pipe with heat shield titanium can increase the effectiveness of exhaust gas on a wide range rpm
– Silencer uses long-fibre packaging low maintenance
Cooling
– High-capacity Denso to provide cooling radiators higher efficiency
– Slim radiators function carefully packaged carrots and fins to enhance the dispersion of heat
Shifting
– The five-speed transmission received a new form of cam and a wider track (5.0 mm to 6.5mm) on the change of battery to enable easier and more consistent gear selection
Brakes
– Front and rear disc brakes petal help reduce unsprung weight
– Disc format helps clean the brake pads for more efficient braking performance
Frame
– New motor 10mm moved farther engine for a slight decrease in torsional rigidity turning framework to accelerate and increase the traction of rear wheels
– All perimeter-aluminum frame is a composite structure comprising forged, extruded and molded components
– The slim profile of the KX450F frame, two-piece radiator shrouds that leave the upper frame spars exposed, and careful design of the body remaining KX450F make the sensation of lightness and reduce under the rider
– Work-style aluminum skid plate and plastic engine guards
Front Suspension
– Kayaba AOS (Air-Oil-Separate) fork keeps oil and air in rooms for amortization of stable performance over long-sleeved
– New reduce friction Kashima Coat treatment added to the inner surface of the tube outside fork
– DLC (Diamond Like Coating) on the fork sliders reduced stiction
Rear Suspension
– UNI-TRAK rear suspension system features revised shock valves to maximize traction for better front / rear balance, acceleration and enhanced controllability
– The shock now has two compression setting, separation of high and low speed setting depreciation
– A single, large port adjustment in the driver improves sensation and setting compared to the previous double-tuning
– New reduce friction Kashima Coat added processing inside of the shell shock
– Oscillating alloy used to cast the tapered spars hydroformed and forged chain Arrache, conical-shaped stringers are to ensure a balance of rigidity and bending necessary aluminum frame.
– Sprocket style roller chain drive reduced whip
Wheels
– 32-spoke rear wheel to reduce unsprung weight
– More lighter and stronger rear hub for increased durability and less unsprung weight
– New Black alumite coated rims for a factory appearance
Gain weight
– Parts of aluminium used instead of steel, including elbow cable clutch, clutch cable nut assembly, mounting fuel tank nuts, seat mounting brackets, front brake clamp and hose ignition stay support
From the cockpit
– Guidon Renthal aluminum are standard
– Light handles short-length feature a special structure to reduce vibrations transmitted through the bars to the rider
– Headquarters uses a slip-resistant top surface for good grip seated and the right side for an excellent rider mobility
