Connected as One

This is the most complete motocross package we’ve ever created. And it’s also the first production bike that allows you to connect wirelessly and dial in your own customized engine settings – and maximize your winning potential.

The new lightweight electric start saves vital seconds when you’re under pressure – and the reverse head engine gets a new high compression top end and optimized ECU for even stronger race winning power.

With its new lightweight frame and refined suspension, this YZ450F gives you improved stability and agility over whoops and through corners. And its slim and compact new bodywork delivers total rider agility combined with factory bike looks.

New reverse head engine

With its newly developed high-tech reverse head engine, this YZ450F gives you a wide spread of power for maximum race-winning potential. Featuring a new higher compression head, piston, cam profiles, cylinder geometry, air intake, ECU and much more – this MXGP-bred design gives you the factory performance you need to power into the victorYZone!

Power Tuner smartphone app

Connect with your dirt bike like never before with the world’s first smartphone app for our Power Tuner! Using your device’s touch screen, you can instantly fine-tune your fuelling and ignition settings to achieve optimum performance. And the sharing function also allows you to compare your settings and race logs with other YZ450F riders!

Lightweight electric starter

The fitment of an ultra-light and extremely compact electric starter gets you up and running at the push of a button. Weight is kept low by the use of a lithium-ion battery, and the electric start’s unique design means that the new engine’s compact external dimensions are the same size as before.

Slim and compact body

As soon as you get on this cutting-edge race bike it feels slimmer and more compact. The smaller 6.2-litre fuel tank and redesigned airbox permit the use of new concave shrouds featuring a larger knee grip area that gives added controllability. As well as reducing weight, this new slimline bodywork also underlines the feeling of lightness and agility.

Newly designed lightweight frame

We’ve developed a new bilateral beam frame that gives increased longitudinal, lateral and torsional rigidity for sharper handling, giving you a real advantage on every corner. And for greater stability and controllability, the electric start engine is repositioned in the new lightweight frame, and new aluminium brackets are used.

Advanced suspension

The YZ450F is the most complete racing package, and as well as its advanced engine and frame, this MXGP-bred winner runs with trick suspension systems. The class-leading AOS forks feature new internals and settings that result in even better damping performance – and the rear shock comes with a lighter spring and increased reservoir capacity.

Dynamic MXGP-bred design

The YZ450F projects a dynamic and coordinated look that complements its advanced engine and chassis technology. A lower and flatter seat gives improved rider mobility, while the front fender as well as the slimmer shrouds and smoother sidepanels reinforce its athletic MXGP-bred factory bike styling.

Lower, slimmer and flatter seat

As well as the smaller tank and slimmer shrouds, the YZ450F benefits from a newly designed seat that is around 20mm lower at its rear section and 8mm lower at the front – as well as being 9mm slimmer. This gives a much flatter seating position, giving you increased front/rear mobility when shifting your weight forwards or backwards.
