2020 Yamaha YZ250F

One of 2020’s best 250cc four-stroke motocross bikes.

Yamaha completely overhauled the YZ250F in 2019 with a new electric-start DOHC engine and twin-spar aluminum frame, updated KYB Speed-Sensitive System (SSS) coil-spring fork and KYB shock, as well as revised bodywork. So, for 2020, this middleweight motocrosser returns unchanged except for a fresh graphics package. Despite ranking fifth among the six 250cc four-stroke MXers in terms of peak horsepower and torque, the 250F’s engine remains one of the best around with the most low-end-to-midrange performance and strong, torquey feel. The engine also makes competitive top-end power, even if it doesn’t carry a gear as long as the KTM 250 SX-F or Husqvarna FC 250.

Suspension is the plushest in class and requires few, if any, changes for a broad spectrum of riders, regardless of their ability or weight. In fact, the YZ250F is the most stable bike in the category with an incredibly planted and predictable feel. As a result, the Yamaha may not be the most nimble or lightest-feeling bike, but it nevertheless corners and handles well. Given that it is such a well-rounded package, the YZ250F remains a highly competitive option in the popular quarter-liter MX segment.

Cycle World’s Annual Ten Best Bikes

In 2014, Yamaha significantly improved the YZ250F with a new reversed-cylinder-head, rearward-slanted, fuel-injected engine. A 450cc motocross bike won the Best Motocrosser award that year, but Yamaha roared back in 2015 with even more updates, which enabled it to claim the coveted honor that year.
