The 2020 Yamaha YZ450F has a starting suggested retail price of $9,399 and is available in Team Yamaha Blue and Gray. Powering this Japanese motorcycle is a liquid-cooled, DOHC, four-valve, 449cc four-stroke engine.
We ran the YZ450F on our rear-wheel dyno to determine peak output from Yamaha’s flagship motocross bike. We documented 48.9 hp at 9,700 rpm and 29.3 pound-feet of torque at 7,100 rpm.
“The new and improved engine on the YZ450F still has an insane amount of power like the 2018 and 2019 model, but it is now more controlled. You can crack the throttle out of a turn and it just pulls so hard, but not so much that it is difficult to keep the front end down.” —Tanner Basso
