Completely re-engineered just last year with new EFI engine, and entirely new frame, minimized body work and new suspension components providing for excellent mass centralization and class leading 450 power with 250-style handling. The critics agree: the YZ450F is the one to beat. Standard 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, as well as the rotational mass of the valve train, helps achieve superior, nimble handling. The 4-titanium-valve cylinder head is matched to a fuel injection system that provides 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 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. Industry-leading suspension with refinements to internal and external components and settings result in superior handling. Stiffer fork springs, new valving and a new fork outer tube improve performance in the mid-to-end stroke and aid fork bottoming resistance. Quick-release quarter-turn Dzus® air box fasteners for tool-less access to the air filter. New Dunlop® MX52 tires offer excellent traction front and rear, especially on hard surfaces. The high-performance ECU provides great bottom end torque plus delivers a strong feeling of power from 3rd gear up while the gear ratios lengthen the powerband and heighten the feeling of power in 2nd and 3rd gear. 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 layout allows the silencer to be behind the side panel closer to the middle of the bike which centralizes the mass for superior handling. The aluminum muffler is positioned closer to the machine s center of gravity as it is almost completely hidden by the side number plate. The layout allows a s
