• More Compact Rearward-Slanted Cylinder

The YZ450F’s distinct rearward-slanted cylinder light and compact design are ideally positioned in the frame for optimized weight distribution. Inside, the head features steep valve angles to allow for an even straighter down-draft intake port, as well as more aggressive cam profiles and larger diameter exhaust header joint that work together with a higher compression bridge-box design piston, DLC-coated piston pin, and longer connecting rod to give YZ450F riders the best balance of class-leading power with an outstanding level of control.

• Yamaha Power Tuner App

The free of charge and industry-exclusive Yamaha Power Tuner app 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

• Bilateral Beam Aluminum Frame

The YZ450F’s compact aluminum frame further refines the instinctive handling that makes this Yamaha one of the sharpest machines in its class. Every aspect has been carefully retuned, with thinner main spar construction, thicker down tubes, revised top triple clamp, and all-new motor mounts that work together to optimize overall rigidity balance for excellent handling, especially in fast, bumpy conditions.
