Yamaha announced its 2021 YZ motocross lineup, including a redesigned YZ250F, and new Monster Energy Yamaha Racing Edition versions of the YZ250F and YZ450F.
Also returning for 2021 are the two-stroke YZ125 and YZ250, and the YZ85 and YZ65 youth models.
2021 Yamaha YZ250F
The 2021 YZ250F receives a new cylinder head with an updated intake port shape, revised exhaust camshaft profile, a new silencer and an updated ECU. Yamaha claims the changes produce strong mid- to top-end power and more peak power while producing strong low-end torque. The intake is all-new, with intake ducts added to the air box lid for added air flow. Yamaha also added a new high flow air filter and reshaped the air cleaner boot while increasing the diameter of the throttle body joint.
Yamaha revised the chassis, changing the lateral beams and engine cradle tube thickness to fine-tune rigidity balance. The engine mounts, top triple clamp and front axle were also modified for rigidity. Both the front and rear suspension received new damping settings, with Yamaha claiming improved cornering performance, traction and bump absorption. The brakes were also updated, with a more rigid front caliper, a more compact rear caliper, and new discs and pads.
Also receiving changes are the crankcase, cam chain and tensioner, water pump, clutch basket and gears 3, 4 and 5, all to improve overall durability.

New 2021 YZ250F: Tune, Race, Win
The new 2021 Yamaha YZ250F has been redesigned for a more competitive, greater performing motocross experience. The new 250cc, liquid-cooled, four-stroke, electric start engine features an all-new cylinder head with an improved intake port shape and new camshaft profile, as well a new airbox and intake track, a new silencer, and an updated ECU. These modifications, along with other refinements like an updated transmission and shift cam, a revised clutch design and improved water pump impeller, all help to produce stronger mid- to top-end power and increased peak power, while retaining its class-leading low-end torque.
Tuned specifically for the 2021 YZ250F, the updated lightweight aluminum, bilateral beam frame, and new engine mounts have been redesigned with all-new flex characteristics to improve bump absorption, traction, and cornering performance. The industry-leading, fully adjustable KYB® coil spring-type fork, with enhanced speed-sensitive damping, provides an exceptional balance between comfort and bottoming resistance while the link-type rear suspension features a KYB shock with revised damping characteristics to match the updated chassis. Other chassis components such as the top triple clamp, handlebar mounts, and front axle were also redesigned to complement the new frame. Improved braking performance is achieved with newly engineered lighter weight front and rear brake calipers, larger surface area brake pads, and redesigned front (270mm) and rear (240mm) discs.
The 2021 YZ250F gives racers the edge right out of the gate. Standard equipment includes electric start, a lightweight lithium battery, advanced fuel injection, a front-positioned intake, and rear-positioned exhaust layout to deliver the widest spread of power with reliable performance while balancing the weight for excellent mass-centralization. Racers can adjust their engine performance straight from their phone using the onboard wireless connectivity through the industry’s only free-of-charge complete tuning system, which is highlighted by the Yamaha Power Tuner App. Once settings are dialed in, racers can then choose between two user-defined ECU maps on the fly via the handlebar mounted dual-mode engine map switch. Complemented by new next-generation Team Yamaha Blue color and graphics, the 2021 YZ250F showcases Yamaha’s race-winning pedigree.
