Welcome to the VictorYZone - New YZ450F
The new 2020 Yamaha YZ450F has been redesigned to provide a lighter, more powerful, and better handling motocross experience. The new 449cc, liquid-cooled, four-stroke, electric start engine features an all-new compact and lighter cylinder head with redesigned combustion chamber shape, steeper valve angles and more aggressive cam profiles.
The rearward-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 aluminium 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 are 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 discs. The overall changes of the 2020 YZ450F deliver increased power output with more controllable linear acceleration and lightweight handling characteristics that mimic a YZ250F. 2020 YZ450F receives a host of upgrades to keep the new model firmly planted in the VictorYZone.
Featuring Yamaha’s advanced racing technology, the new 2020 YZ450F has been updated to give racers the edge right out of the gate. Standard equipment including electric start, a lightweight lithium battery, advanced fuel injection, and a wrap around rear-positioned exhaust deliver powerful and reliable performance featuring industry leading mass-centralisation.
Racers can achieve quicker, smoother race starts with Yamaha’s Launch Control System, adjust their on-track performance usinga smartphone thanks to the Yamaha Power Tuner App, andchoose between two user defined ECU maps on the fly with the handlebar mounted dual-mode engine map switch.
The new 2020 YZ450F will be available from dealers next month in Team Yamaha Blue and Grey – pricing and availability are to be announced.
Also returning for 2020 is the championship-winning Yamaha YZ250F, along with Yamaha’s legendary two-stroke lineup featuring the YZ250, YZ125, YZ85 and YZ65.
