The YZ450FX is a cutting edge weapon specially honed for the bush. It shares the revolutionary rearward-slanted cylinder design of our YZF/WR range and delivers a controllable, torquey power character with strong top-end power tuned specifically for enduro racing.

A YZ450F Bilateral Beam aluminium frame combines with industry-leading, KYB® twin chamber suspension to provide a shorter wheelbase and quicker steering experience to get through the trees – fast.

This model sports a powerful 270mm front brake for outstanding machine control, a model specific clutch system and new switch-free electric start.

All this plus an 18-inch rear wheel and XC racing tyres means the YZ450FX is ready to win straight from the crate.

Product Description

All new 2021 YZ450FX
In the world of competition enduro models, the 2021 YZ450FX has been reworked to remain at the top of its class. The new 449cc, liquid-cooled, four-stroke, electric start engine features an all-new compact cylinder head with redesigned combustion chamber shape, and steeper valve angles. The rearward-slanted cylinder houses a higher compression piston with low friction rings attached to a longer connecting rod. The transmission has been refined to provide smoother shifting, and a more efficient crank breather system has been adopted to decrease pumping losses. In all, the lighter, more compact engine produces increased power across the entire RPM range for stronger and more linear pulling power.

The latest evolution of Yamaha’s lightweight aluminium bilateral beam frame has been redesigned with all-new flex characteristics that provide improved cornering performance, traction and bump reaction to give the rider more confidence to push harder in any off-road condition. Other chassis components such as engine mounts, top triple clamp and front axle, as well as the class-leading KYB® suspension with enhanced compression and rebound characteristics were carefully refined to reduce weight while improving handling and performance.

To bring the new package to a stop, the 2021 YZ450FX features a newly designed front brake caliper, brake pads and front and rear disc. The combined changes to the new 2021 YZ450FX deliver increased power output with more controllable, linear acceleration and lightweight handling characteristics that mimics the YZ250FX.

To further showcase the YZ450FX’s cross country edge, electric start, a lightweight lithium battery, and advanced fuel injection are all standard features. The front-positioned intake and rear-positioned exhaust layout deliver the widest spread of reliable power while balancing the weight for excellent mass-centralisation.

This enduro racer also continues to feature Yamaha’s advanced racing technology. The dual-mode switchable engine mapping and wireless connectivity is handled through the industry’s only free of charge complete tuning system, which is highlighted by the Yamaha Power Tuner App. This system allow racers to adjust their engine performance using their smartphone, while the Yamaha Launch Control System helps to achieve quicker, smoother race starts. With new next generation Team Yamaha Blue colours and graphics, the 2021 YZ450FX showcases Yamaha’s cross-country competitive edge.

In Australia, both YZ250FX and 450FX come with a rec rego kit – that includes a headlight – to enable these models to be registered in applicable states such as VIC.
The otherwise unchanged YZ125X, YZ250X and YZ250FX are also available in the new trick blue/black plastics combo and all come with the rec rego kits in Australia.

YAMAHA POWER TUNER APP
Yamaha’s exclusive power tuner app puts the flexibility and precision tunability of the GYTR power tuner into your smartphone. Making fueling and ignition timing changes instantly and uploading them to the bike via the onboard WiFi system. This allows ultimate track side tuning.

COMPACT BODY AND SEAT DESIGN
The YZ450FX features stylish body work for tip to tail. Including a large 8.2 litre, mass-centralised fuel tank, the body design is narrow for more comfortable knee grips amd a feeling of solid control. As the seat is lower and narrower the rider has more room to move aboard the machine.

POTENT FUEL-INJECTED ENGINE
A high-compression cylinder head, forged piston, aggressive cam profiles, cylinder geometry and much more work together to give the YZ450FX riders the ideal power spread in challenging off-road racing conditions.

ADJUSTABLE ENGINE MAPPING
A handlebar-mounted map switch allows the rider to quickly select between preloaded engine maps. these are loaded and configured into the power tuner app- to account for changing track and weather conditions.

BILATERAL BEAM FRAME
