Innovation meets acceleration. The 449cc liquid-cooled DOHC 4-stroke YZ450F sports industry-leading suspension; electric start and the smartphone power tuner app - so you can dial in your ride.Features may include:
The YZ450F’s distinct rearward-slanted cylinder design â€“ complete with rear exhaust and forward-mounted intake system â€“ features a cylinder head that works with the frame geometry for optimized front weight distribution. Inside; the engine features a long; straight intake tract; aggressive cam profiles; high-compression “box bridge” 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 â€“ again â€“ Yamaha created the Power Tuner app; which brings the power of the GYTR Power Tuner to your iOS® or Android® device. Using WiFi to connect 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.
The YZ450F’s compact frame further refines the instinctive handling that makes this Yamaha one of the sharpest machines in the class. Large upper frame bracing provides rigidity and durability; while rear frame spars and tuned engine mounts centralize mass for the best possible balance of bump absorption; stiffness and rider feeling.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.
The 4-position adjustable handlebar mounts are rubber mounted to improve comfort; reduce handlebar vibration and allow riders to adjust the bar position; while the handlebar itself is strong but lightweight to centralize overall mass.Embedded Graphics
Yamaha’s unique embedded graphics are built into the bodywork for extended durability; resisting both peeling and damage.
