New 2020 YZ450F: Tune in to Victory
The new 2020 Yamaha YZ450F has been redesigned to provide a lighter, more powerful, and better handlingmotocross experience. The new 449cc, liquid-cooled, four-stroke, electric start engine features an all-new compact cylinder head with redesigned combustion chamber shape, steeper valve angles and more aggressive cam profiles. The reward-slanted cylinder houses a higher compression piston with low friction rings attached to a longer connecting rod. The transmission has been refined to provide smoother shifting, and a more efficient crank breather system has been adopted to decrease pumping losses. In all, the lighter, more compact engine produces increased power across the entire RPM range for stronger and more linear pulling power.
The new motor is housed in the latest evolution of Yamaha’s lightweight aluminum bilateral beam frame, which has been redesigned with all-new flex characteristics and provides improved cornering performance, traction and bump reaction to give the rider more confidence to push harder. Other chassis components such as engine mounts, top triple clamp and front axle, as well as the class-leading KYB® suspension with enhanced compression and rebound characteristics were carefully refined to reduce weight while improving handling and performance. To bring the new package to a stop, the 2020 YZ450F features a newly designed front brake caliper, brake pads and front and rear disc. The overall changes of the 2020 YZ450F deliver increased power output with more controllable linear acceleration and lightweight handling characteristics that mimic a YZ250F.
