YAMAHA POWER TUNER APP
The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to an iOS® or Android® device, allowing owners to adjust air/fuel mixture and ignition timing, log race set-up information, and monitor a range of data such as maintenance and system diagnosis, engine run time, and more. The newest version of the app has been revised to be more user-friendly, with new features include an intuitive "Simple Tuning" slide bar for engine mapping, Traction Control tuning, lap timer, and helpful engine and suspension tuning guides.
Class Leading Suspension
World renowned suspension performance straight out of the box. High-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional bump absorption, and now features toolless compression clickers for easy adjustment and new fork covers to help prevent debris damage. The linkage-type rear suspension features a KYB® shock with cross-country focused damping characteristics to match the new YZ450FX's refined chassis.
450CC 4-STROKE ENGINE
The new 2024 YZ450FX's advanced four-stroke engine has been completely redesigned to be lighter, more compact, higher revving and more powerful across the entire rev range. Among the changes are new exhaust and intake port shapes, larger diameter titanium intake valves, new piston, cylinder, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. Additionally, ECU settings are tailored to suit the specific needs of cross country and enduro competition.
ADJUSTABLE ENGINE MAPPING
New, lightweight handlebar-mounted switchgear allows the rider to quickly select between preloaded engine maps - loaded and configured in the Power Tuner App - to adjust for changing riding conditions. Map 1 provides more responsive, quicker revving engine characteristics while Map 2 provides smoother response and slower revving characteristics for when traction is limited.
BILATERAL BEAM FRAME
Striking the perfect balance of precise cornering performance and handling stability, the redesigned aluminium bilateral beam frame consists of more than 10 different aluminium components welded together with YZ450FX-specific XC-tuned engine mounts. The result is a better handling machine with lighter feel, improved bump absorption and increased traction, allowing the rider to enter corners with greater confidence and more line choices.
CROSS COUNTRY FEATURES
With the electric starting system, a 7.8L fuel tank, rugged plastic skid plate, 18-inch rear wheel and XC racing tyres, the YZ450FX is ready to win right out of the box.
