Yamaha draws 12 YZ models for racing 2021, ranging from YZ65 neophyte ready to the new YZ450F Monster Energy Yamaha Racing Edition supercross. Let's go over the line 2021 de Yamaha YZ, a dozen to compete.



Yamaha YZ450F 2021

The top end of the engine for the flagship motocrosser has a new high compression stock with steeper valve angles, more aggressive cam profiles, a forged piston and a magnesium valve cover. Power that is a higher flow air filter with improved air intake efficiencies, with the spent charge coming out through a larger exhaust pipe connector. The lower end gets a longer connecting rod.

Yamaha has adjusted the stiffness distribution of the frame with changes in its side beams and the thickness of the tubes of the engine base. Engine mounts, triple top clamp and front axle have also caught the eye of Yamaha chassis engineers. To match those changes, suspension damping changed, and Yamaha claimed “improve cornering performance, traction and shock absorption”.

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

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

Yamaha YZ250F 2021

The power of the Yamaha YZ250F 2021 receives the most attention this year. The upper end of the YZ250F has a new cylinder head, and the cams have new profiles. Airbox and intake route are new, just like the silencer. Optimizing those changes is a new ECU, with the goal set by Yamaha of “higher mid-range to high power and higher maximum power, while retaining its class-leading low-end pair”. The clutch and transmission also receive updates, together with the impeller of the water pump.

Also, the YZ250F gets the same chassis and suspension modifications as the YZ450F.
