2020 YAMAHA YZ450F

TUNE IN TO VICTORY

Class leading performance and suspension along with the smartphone power tuner app make this the bike of choice for race winners.

Features may include:

ENGINE

• More Compact Rearward-Slanted Cylinder

The YZ450F’s distinct rearward-slanted cylinder design is now even lighter and more compact than before, ideally positioned in the frame for optimized weight distribution. Inside, the engine features a long, straight intake tract, aggressive cam profiles, a new high-compression, bridge-box piston design with DLC-coated piston pin, and more. Together, these details give the rider an ideal balance of open-class power with exceptional controllability.

• Yamaha Power Tuner App

Breaking new ground in the industry – again – Yamaha created the Power Tuner app, which 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 Mapping

A 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/SUSPENSION

• Aluminum Frame

The YZ450F’s compact frame further refines the instinctive handling that makes this Yamaha one of the sharpest machines in the class. Every aspect has been carefully retuned, with thinner main spars, thicker down tubes and all-new motor mounts that work together to shed weight and boost handling feel at the limit.

• Compact Body and Seat Design

The YZ450F features stylish bodywork from tip to tail, including a compact fuel tank specifically designed for motocross demands. In addition to shaving weight, the body design is narrow for more comfortable knee grip and control feeling, while the narrow seat gives the rider additional room to move aboard the machine.

• Class-Leading Suspension

Industry-leading, fully adjustable KYB® coil spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption, for race-winning handling performance. The linkage type rear suspension features a KYB® shock with specially-tuned damping characteristics to match the YZ450F chassis.

ADDITIONAL

• Adjustable Handlebar Mounts

The 4-position adjustable handlebar clamp is rubber mounted to improve comfort, reduce handlebar vibration and allow riders to adjust the bar position, with reshaped mounts that trim weight down even further.

• Embedded Graphics

Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.

NEW FOR 2020

• Ultimate Open Class YZ

Lighter. More Powerful. Better Handling. To meet these essential targets, the 2020 YZ450F was examined under a microscope. A ultra-compact motor was developed, housed in the latest evolution of Yamaha’s aluminum Bilateral Beam frame. Chassis components and suspension settings were carefully refined for excellent handling feel. And weight was shaved everywhere, from the footrests to the electrical system.
