2021 Yamaha YZ450FTUNE IN TO VICTORYClass-leading performance and suspension and the smartphone Power Tuner app make the YZ450F the bike of choice for race winners.Features may include:ENGINEMore Compact Rearward-Slanted CylinderThe YZ450F’s distinct rearward-slanted cylinder light and compact design are ideally positioned in the frame for optimized weight distribution. Inside, the head features steep valve angles to allow for an even straighter down-draft intake port, as well as more aggressive cam profiles and larger diameter exhaust header joint that work together with a higher compression bridge-box design piston, DLC-coated piston pin, and longer connecting rod to give YZ450F riders the best balance of class-leading power with an outstanding level of control.Yamaha Power Tuner AppThe free of charge and industry-exclusive Yamaha-created Power Tuner app brings the power of the GYTR Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.Adjustable Fuel MappingA handlebar-mounted map switch allows the rider to quickly select between preloaded engine maps—loaded and configured in the Power Tuner app—to account for changing track and weather conditions.CHASSIS/SUSPENSIONBilateral Beam Aluminum FrameThe YZ450F’s compact aluminum frame further refines the instinctive handling that makes this Yamaha one of the sharpest machines in its class. Every aspect has been carefully retuned, with thinner main spar construction, thicker down tubes, revised top triple clamp, and all-new motor mounts that work together to optimize overall rigidity balance for excellent handling, especially in fast, bumpy conditions.Compact Body and Seat DesignThe YZ450F features stylish bodywork from tip to tail, including a compact fuel tank specifically designed for motocross demands. The lower, forward-positioned handlebar position and the firmer seat assist the rider in keeping their weight forward during aggressive riding.Revised Class-Leading SuspensionIndustry-leading, fully adjustable KYB® coil spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption. The linkage-type rear suspension features a KYB® shock with damping characteristics to match the YZ450F chassis.ADDITIONALTriple Clamp with Adjustable Handlebar MountsThe top triple clamp design balances rigidity for improved steering feel while the 4-position adjustable handlebar clamp is rubber-mounted for comfort, reduced handlebar vibration and easily tunable bar position.Embedded GraphicsYamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.Race-Winning DetailsThe YZ450F includes top-spec details, including 1-1/8” aluminum tapered handlebars, wider yet lighter foot pegs, a quick-adjust clutch perch, stylish blue rims and gold chain.
