YZ450F Featuring a "reversed" rear slanted engine design for mass centralization, minimal bodywork and a proven KYB "SSS" suspension system, the YZ450F offers class leading power in a 250 sized chassis. The YZ450F balances the three essential elements of an ultimate motocrosser: easy cornering, lightweight and compactness and a deep, useable power band. Key Improvements for 2017 Revised air filter cover & fasteners Revised rear wave-style brake rotor New tire tread pattern front & rear Key Features Revolutionary reversed engine design with front mounted FI system & rear exiting exhaust Mass centralizing rearward-slanted-cylinder helps keeps weight centred in the chassis Launch Control System "Battery-less" 44 mm throttle body FI & easy access airbox Compact aluminum Bilateral Beam frame & aluminum swingarm Industry-leading, fully adjustable KYB® "SSS" fork & Monocross rear suspension Large 270 mm front disc brake & twin piston caliper GYTR® Power Tuner Ready Engine Design goals for the YZ450F are a balance of easy cornering, a lightweight & compact feeling due to excellent mass centralization and a deep power band tuned for excellent "ride-ability & controllability". "Reversed" liquid-cooled, 450 cc, DOHC, 4-valve (titanium), 4-stroke, single with fuel injection. Rearward slanted, reversed cylinder design. Rearward slant moves a significant amount of rotating weight toward the centre of the chassis Rearward slanted design centralizes mass for excellent handling & a light feel "Reversed" engine design (FI system is front mounted, exhaust exits from rear of cylinder). FI throttle body & air box are front mounted, providing a straight intake path Straight intake path into the cylinder, provides optimum fuel / air flow for excellent power Front mounted intake keeps fuel cooler since engine heat has less effect on incoming fuel (cooler fuel is more dense & increases power) Design centralizes mass for light, agile handling Compact 4-valve cylinder head features a 12.5:1 compression ratio. 37 mm titanium intake valves & 30.5 mm titanium exhaust valves 4-valve design offers optimum flow for excellent power & torque Compact combustion chamber design Lightweight, hollow intake & exhaust cams. Excellent power & controllability in the low to mid rpm range Strong high rpm power Lightweight titanium valves use load-reduced oval valve springs. Titanium reduces reciprocating weight & allows for a higher rpm limit (40% lighter than steel valves) Reduced friction (load reduced) valve springs Automatic cam chain tensioner. Reduces maintenance & mechanical engine noise Special cam chain "sliders" reduce internal frictional losses Lightweight, ceramic composite plated aluminum cylinder. Reduced weight... No sleeve or heavy liner... Plating is sprayed directly on the aluminum block Ceramic coating insures faster, more uniform heat dissipation Coating enhances the thin film of oil between the cylin
