Honda redesigns its Gold Wing from the ground up for 2018
2014 Yamaha® YZ®450FTHE ALL-NEW 2014 YZ®450F
Featuring a new EFI engine, an entirely new frame, minimized body works and new suspension components providing for excellent mass centrlization nad class leading 450 power with 250-style handling.
Key Features May Include:
YZ450F’s revolutionary rearward-slanted-cylinder design is an innovative approach to achieve unmatched mass centralization. Concentrating the motorcycle’s heaviest components (engine mass, fuel tank, exhaust system, and airbox) toward the center of the machine helps achieve superior, nimble handling.
The 4-titanium-valve cylinder head is matched to a newly recalibrated fuel injection system to provide superb power feeling across the rpm range. The adjustable fuel injection system uses a 44mm throttle body fed by a high pressure battery-less electric pump to ensure optimum fuel atomization and air/fuel calibration for excellent readability in a wide range of riding conditions. The YZ450F instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions.
The new aluminum Bilateral Beam frame offers a superb rigidity balance and, with new settings to already class leading front and rear suspension, provides unmatched lightweight handling and cornering. For 2014, the steering head pipe is moved 10mm closer to the rider, making for a more compact chassis dimension and placing more weight bias on the front wheel which translates to an even more precise and instinctive handling character.
Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons.
For 2014, the top-end... Piston, intake and exhaust valves, ports, valve mechanism, ignition timing, and fuel injection mapping have all been meticulously revised, resulting in improved combustion and outstanding engine performance throughout the power band, with a focus on controllability.
The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaust pulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This new layout allows the silencer to be positioned 186mm further forward behind the side panel, closer to the middle of the bike which centralizes the mass for superior handling.
A newly designed aluminum Bilateral Beam frame is adopted in which the head pipe is moved 10mm closer to the rider. The overall dimensions are roughly the same as the frame of the 2013 YZ250F. This gives the YZ450F a new compact chassis that provides the most instinctive handling in the 450 motocross class.
A new layout for the fuel tank and air cleaner box gives the machine a slimmer feeling between the legs as well as positions fuel tank mass closer to the center of the bike which improves handling feel. Furthermore, the air box can now be accessed without removing the fuel tank for easy serviceability of the new larger air cleaner element.
“In-mold graphics” technology is a method in which the graphics are molded into the radiator shrouds for improved decal durability and reduced scratches.
