The Yamaha YZ450F is proof that the dyno doesn’t tell the whole story in terms of how powerful a motorcycle is. Although it makes less horsepower and torque than the Honda CRF450R, Husqvarna FC 450, and KTM 450 SX-F from 6,400 rpm until peak on our in-house dyno, the bLU cRU’s flagship motocrosser is the most aggressive and torquey machine in the 450cc category. Luckily, for those who want to tame the YZ450F’s fire-breathing capability in stock trim, the free Power Tuner app can do just that by wirelessly connecting to the bike’s onboard Wi-Fi system, at which point EFI tuning adjustments can be made. As far as peak figures, the YZ450F cranks out 53.1 hp at 9,700 rpm and 32.7 pound-feet of torque at 7,400 rpm.
“Delivering the most hit from the bottom-end to midrange out of all the 450 motocross bikes, the 2021 Yamaha YZ450F actually has too much hit for my liking with the stock map setting. I prefer the Magic (Controlled Acceleration) Map as it works good for all track conditions (morning and afternoon). Still, if you have bad throttle control, you will tire your arms holding onto this powerful bike.” —Cody Johnston
