2021 Yamaha YZ Lineup First Look: The Dirty Dozen Racers

Yamaha brings 12 YZ models for racing in 2021, running from the neophyte-ready YZ65 to the new supercross-platform YZ450F Monster Energy Yamaha Racing Edition. Let’s go over the 2021 Yamaha YZ lineup—a dirty dozen for racing.

MOTOCROSS

2021 Yamaha YZ450F

The top-end of the motor for the flagship motocrosser gets a new high-compression cylinder head with steeper valve angles, more aggressive cam profiles, a forged piston, and a magnesium valve cover. Feeding that is a higher-flow air filter with improved air intake efficiencies, with the spent charge exiting through a larger exhaust headpipe connector. The bottom end gets a longer connecting rod.

Yamaha has fine-tuned the rigidity distribution of the frame with changes to its lateral beams and the thickness of the engine cradle tubes. The motor mounts, top triple-clamp, and the front axle have also gotten the attention of the Yamaha chassis engineers. To match those changes, the suspension damping has been modified, with Yamaha claiming “improve[d] cornering performance, traction and bump absorption.”

With a faster motor, Yamaha also gives the YZ450F a new braking system, with a focus on improved feel.

2021 Yamaha YZ450F Price: $9399 MSRP. Available: July 2020.

2021 Yamaha YZ450F Monster Energy Yamaha Racing Edition

Unlike the factory editions from Honda, Husqvarna, and KTM, which include functional updates, the YZ450F Monster Energy Yamaha Racing Edition is purely a graphics package.

2021 Yamaha YZ250F

The 2021 Yamaha YZ250F’s power gets the most attention this year. The YZ250F’s top-end has a new cylinder head, and the cams have new profiles. The airbox and intake track are new, as is the silencer. Optimizing those changes is a new ECU, with the Yamaha-stated goal of “stronger mid- to top-end power and increased peak power, while retaining its class-leading low-end torque.”  The clutch and transmission also get updates, along with the water pump impeller.
