The Main Functions

YZ450FX is all new products for 2019, based on Yamaha’s flagship off-road motorcycle model YZ450F, with many additional features and unique settings, making YZ450FX the ultimate GNCC /Woods racer. High compression cylinder heads, forged pistons, aggressive cam profiles, cylinder geometry, and many other features together provide YZ450FX drivers with the ideal power distribution under challenging GNCC racing conditions.

Yamaha’s extraordinary Power Tuner application brings the adaptability and exact customizability of GYTR Power Tuner to your cell phone. Immediately change the fueling and ignition timing and upload it to the bike via the onboard Wi-Fi system to achieve excellent trackside adjustments.

The Yamaha YZ450FX 2019 Powerful Dirt Bike uses a compact starter motor and ultra-light lithium battery, which maintains the convenience of the button start, can be quickly restarted under pressure, and comfortable ride without the clock. Yamaha uses KYB spring-loaded front forks on all of our YZ models. It has industry-leading features and is easy to install on the track-these front forks can be used directly on the podium.

Yamaha’s double-sided beam aluminum frame has a central beam, an engine bracket dedicated to FX, and an engine mounting location that concentrates mass. It achieves an ideal balance between turning feel and straight-line confidence.

New for 2019

For 2009, the new YZ450FX captures all of the improvements found on the YZ450F motocrosser, including the advanced graphics, suspension, engine, and electronics – including Yamaha’s exclusive Power Tuner smartphone app – with adjustments tailored according to the needs of the national competition.


The YZ450FX’s unique rear-mounted cylinder design – complete with rear exhaust and upper-mounted drinking system – features a cylinder head that works well with this aerodynamic weight distribution. Inside, the engine showcases a specific dining tract, with aggressive cam profiles, high-compression “box bridge” piston designs and DLC-locked piston pins, and more. Finally, the Yamaha YZ450FX 2019 Powerful Dirt Bike shows the exact ECU settings to suit the needs of cross-country riders.

The YZ450FX contains a compact electric Starter system for slow restoration on track and easy addition of anywhere else. Sturdy with high-weight and Ultra-lightweight four-cell lithium-ion batteries, the system adds less weight. The advanced map-activated map allows the rider to quickly choose between engine maps that are pre-loaded and optimized in the Power Tuner app – to be responsive to changing track and weather conditions.

Breaking new ground in the motorcycle industry – again – Yamaha has developed the Power Tuner app that brings the power of the GYTR Power Tuner to your iOS or Android device. Using Wi-Fi connectivity to the bike on-board on-the-bus network, the app allows owners to configure air/fuel mixture and fire time maps to capture engine performance of track status, record step information, and track data types such as configuration and system diagnostics, engine running time, and more.

The engine breathes from the 44mm Mikuni throttle body fed with a high voltage pump to detect optimum fuel atomization and power across different riding conditions. YZF450FX’s wide-ratio five transmission speed guarantees cross-country to make the most comfortable gearing choices in open areas.

Chassis / Suspension

The top frame brace provides ruggedness and durability, and the rear frame spar and cross-country tuning engine mounts centralize the mass for a maximum balance of bump absorption, stiffness and driver feel.

The Yamaha YZ450FX 2019 Powerful Dirt Bike features a sleek body from end to end, including a large 2.15-gallon, bulk-focused fuel tank, and the body design is narrower for a more comfortable knee grip and feel of control, and the closer and lower seats allow occupants to board.

The industry’s best fully adjustable KYB coil spring-type fork with speed-sensitive damping provides an excellent balance between handling and bump absorption for outstanding handling performance in races. The linkage-type rear suspension has a KYB shock with damping characteristics specially tailored to the YZ450FX chassis. Also, in 2019, settings were modified for optimal GNCC® performance for both front and rear systems.

An all-new large 270 mm front disc brake combined with the aggressive pad material that offers excellent braking performance and control, providing outstanding braking performance and machine control. The YZ450FX features an Enduro-only tire for an ideal balance of traction and durability with an 18-inch rear wheel. The new cross-sectional profile of each wheel is a computer designed to diminish valuable weight without compromising strength.

Additional Features
